Russia’s 3D Printed Home

Russia’s 3D Printed Home

The house built by Apis cor in Russia occupies 400 square feet of space and is very well designed. You can locate the house sitting to the south of Moscow. This project was completed in 2017 and has been one of the most popular additions to the 3D printed building.

There is something different about this project that isn’t found usually. The entire project was completed onsite. The construction was done using concrete material. Because there was no involvement in transportation and installation, the project cost much less than expected.

Not just that, the complete house was printed in about 24 hours. In addition, mixing some solid elements with the liquid polyurethane, the company constructed heating insulation. And, this was also accomplished on-site.

The house was designed from the exterior and interior to provide it the finishing touch. Painted yellow from outside and flaunting the contemporary style design inside, the house did make us all go crazy.

It has wooden flooring. And, as stated by the company, the total cost for building the house was not more than $10,134.

The Conclusion

We invest a lot in buying houses. And, it is not very often that we are able to customize the design of the house as per our will. But 3D printing provides us with more flexibility, not only with the style of house you would prefer but the budget as well.

There is already so much going around construction using 3D printers, it will be soon when we would be staying in 3D printed buildings. Although that still would take some time, we do know it is possible.

Digital Light Processing (DLP) 3D Printing – Simply Explained https://pick3dprinter.com/dlp-3d-printing/ Sat, 04 Jul 2020 21:18:45 +0000 https://pick3dprinter.com/?p=6154 Table of Contents

DLP is an abbreviation for Digital Light Processing. Amongst the very many types of categories in which additive manufacturing is classified, DLP 3D printing falls under Vat polymerization.

In this category, a liquid photopolymer resin is used to solidify under a light source. The other type of technology that also falls under the family of VAT polymerization is known as SLA.

SLA is an abbreviation for Stereolithography. In SLA 3D printing a build platform, an elevator platform, a tank filled with resin, and a light source are used with galvanometers to produce parts.

Printers based on the SLA technique start by lowering the build platform into the resin tank. Here the galvanometers are used to monitor the laser beam.

If the laser beam does not reach the bottom of the tank, the print is not accurate. Galvanometers operate with G codes, ensuring the laser beam reaches the bottom of the tank.

The laser solidifies the layer which is printed using the resin. As soon as one layer is solidified, the build platform moves one layer about that. This process is repeated until all the layers of the part are completely solidified.

Now that you have known how SLA 3D printing works in general, you’d be able to learn by comparing it with working with DLP printing. But before that let’s have a little brief about how DLP 3D printing was invented.

How was DLP 3D printing invented?

The man credited for the technology’s invention is Larry Hornbeck. He is the creator of Texas instruments and is said to have created DLP 3D printing in 1987.

In DLP, digital micromirrors are used. Each mirror that is used actually represents a pixel in the image that allows display.

Now, let’s see how the technology actually works.

back to menu ↑

Working of a Printer Based on Digital Light Processing

As you have already read that a laser is used in SLA 3D printing, to solidify the resin. Here in DLP 3D printing, a light source does the same work.

This is the primary difference between both technologies. However, an in-depth working style would help you if you are a designer who is using other technologies for 3D printing, or a newbie in additive manufacturing.

So, let’s look at the working step by step:

  1. The build platform of a 3D printer is positioned inside the tank that is filled with liquid photopolymer. The height between the build platform and the tank is approximately one layer long.
  2. After having the build platform correctly positioned, a ray of light from the light source is allowed to pass. This ray of light creates the next layer by selectively curing and solidifying the photopolymer resin. The light ray has a predetermined path on which it travels. Here is where galvanometers play a huge part. Since the path is predetermined galvanometers are placed at intervals to monitor this path. After solidifying one layer, the same process is repeated for the other layer.
  3. The build platform moves at a safer distance as soon as the solidifying of one layer is finished. Alongside the movement of the build platform, the sweeper blade is constantly re-coating the surface.
  4. For parts that demand very high thermal and mechanical properties, post-processing under light rays is required. That is done in the fourth step which is optional sometimes.

The basic diagram of a DLP 3D printer would let you know better about this process. So here you go:

DLP 3d printing technologyCredit: bitfab.io

The solidifying of liquid resin is a process that is called photopolymerization. During this solidification, the monomer carbon chains that compose the liquid resin are activated by a ray of light.

This activation creates solidification and unbreakable bonds between each other.

Because this process is irreversible, it is not possible to convert parts that are manufactured by DLP 3D printing, back to the liquid phase. DLP 3D printing using thermoset polymers and not the usual thermoplastic polymers.

General characteristics of DLP 3D printing:

Like other techniques, DLP 3D printing has some characteristics that should be known before printing is done using this technique. Here is our attempt to list some of them:

back to menu ↑

Parameters that are related to Printer

Most parameters cannot be changed as they are already fixed in DLP printers. The only inputs that are to be given by the user are the layer height and orientation.

The typical layer height in DLP ranges between 25 and 100 microns. The lower heights capture curved geometries more accurately than the upper ones. DLP printers come with two orientations namely: bottom-up and top-down.

The top-down DLP printers have the light source placed above the resin tank. The build platform begins its journey from the very top of the resin vat and moves downwards layer by layer.

While in the bottom-up DLP printers, the light source is placed under the resin tank. After every layer, the solidified resin is detached from the bottom of the tank and the build platform starts to move upwards.

One should know about these orientations of printers before putting his/her step in DLP printing.

Support Structure

3d printing support structure

The orientation of the DLP 3D printer would determine the amount and location of support. These structures are printed in the same material and should be taken out manually after the printing is completed.

In top-down DLP printers, the support part can be printed in any position. However, they are generally printed flat to minimize the amount of support and a total number of layers.

While in bottom-up printers support structures are more complicated. The forces that are attached after the resin is solidified can cause these structures to detach themselves from the build platform.

So extra care needs to be taken. For this reason, the support structures are oriented in angle in which reduction of support is not a primary concern.

After reading about printer parameters and support structures, one must know as a DLM designer about a problem called curling.

Curling

curling-and-warping

As in FDM, there is a problem of warping, in Digital Light Processing there is curling. This problem occurs during the solidifying of resins.

The shrinkage in resin, while they are exposed to light, causes internal stresses inside the material. Whenever there is a new layer developed above the already solidified layer, this shrinkage takes place.

This is a natural problem that occurs in the material due to the inherent nature of technology so it cannot be avoided. Let’s take a look at a problem that occurs in every technology i.e. Layer Adhesion.

Layer Adhesion

Parts that are printed with DLP printers have isotropic mechanical properties. The nature of this DLP printed parts is given to the ray of light which passes through the liquid resin.

Later this ray of light is used to solidify layers and fuse them together to a very high degree. In DLP printing, solidifying continues even after the completion of the printing process.

This improves the hardness and temperature resistance of the material that is produced by DLP printing and it also makes it brittle.

With Layer Adhesion, we complete the list of characteristics that are seen and needed to be taken care of in DLP printing. Now it is time to take a look at a comparison between DLP and SLA.

Comparison Between DLP and SLA

SLA & DLP (Stereolithography & Digital Light Processing)

There is a benefit when you are using the DLP 3D printer over the SLA printer. The difference between them is speed. DLP printers are speedier to operate and produce a print faster than SLA 3D printers.

However one should such an idea after reading this that DLP printing does not have a limitation.

A DLP 3D printer uses a digital projection screen so the resolution of your print directly depends on the resolution of your projector.

The greater resolution your ray of light has, the greater resolution your product will have. While in the SLA technique, this is not the case. Even cheaper devices can produce higher resolutions.

The reason behind the expensive range of DLP printers is this only. SLA printers are available in every range, whereas DLP printers are not that widely available, especially to small businesses because they are expensive.

DLP 3D printers produce the boxy surface finish. The voxels of these printers are rectangular, so curved sections of a print does not tend to have a very smooth finish compared to SLA printers. But this problem can be solved by sanding after the part is printed.

A similarity between DLP and SLA printers is that both use resins. So mostly they can be used interchangeably. However, one needs to decide whether he/she wants to manufacture parts with a light source or a laser beam.

After seeing the comparison between DLP and SLA printing, let’s take a look at a few DLP printers which are the most recommended.

Limitations of DLP 3D printing

  • Because the parts produced by DLP 3D printing are brittle, they are less suitable for functional prototypes.
  • The mechanical properties of the parts that are produced with the printing often degrade with time when exposed to sunlight.
  • Support structures are always required in this process and on post-processing while they are removed, they leave a mark on the product.
back to menu ↑

The Conclusion:

DLP printing can produce parts with high dimensional accuracy and intricate detailing. The parts that are produced using this 3D printing have a smooth surface finish and are ideal for visual prototypes.

Industrial DLP printing can produce parts of bigger build volume such as 1500 mm * 700 mm * 500 mm.

Because of these characteristics, DLP printing has always been a top choice of designers and engineers who require higher accuracy and intricate detailing in their objects.

Above all the advantages it offers, this 3D printing technique is also faster than SLA and other 3D printing techniques. So, if one wishes to produce parts, wherein the print time is quick, he/she can go for DLP.

However, apart from speed, one must take into consideration the different limitations of the technology.

For example, if you wish to produce a functional prototype that needs to go through some amount of stress, this technology may not be a suitable one. This is because it produces brittle parts.

Moreover, you must be ready to invest time in post-processing when working with DLP 3D printing. Apart from that, the technology is still growing and we hope to see better prospects in the future.

There are a plethora of factors to consider when weighing up the 3D print online services and bureaus out there. Hence, you must select the one that complies with your needs. Here are a few criteria that may help you decide better along with a few popular recommendations.

Criteria for Choosing the Right 3D Print Online Service

Here are the things that matter when choosing the need to create an online 3d print design.

back to menu ↑

Time

You needed your part yesterday, and the closest thing to a time machine is an additively manufactured piece on the express train to tomorrow. Fortunately, some 3D printing service providers offer rushes on jobs should you not be too picky about the material it prints in.

back to menu ↑

Privacy

It’s a natural assumption that most 3D printing services operate with the intent to foster trust with their users — who are uploading potentially sensitive models. Most of these are quick to declare that in uploading your file for manufacture, you are granting a non-exclusive license giving the company the provision to fabricate your model. However, there are occasions where you, as the user, need airtight confidentiality regarding the files you are uploading.

back to menu ↑

Material Choice

There is a surprisingly diverse array of materials available to 3D printing technologies, making even the most discerningly specific of jobs a possibility. From difficult gold parts created using 3D printed molds for investment wax casting to flame-retardant casings printed in impossible shapes — the limitations become less by the day.

back to menu ↑

Cost

The factors affecting the final cost of a 3D printed part are myriad. You have some little power to influence the cost of the parts you order, be it through using a 3D print service that is local to where you need the printed piece to be and being flexible with the materials you use.

Let’s look at the recommendations and then at the other two criteria in the conclusion of the article.

3D Print Heat Sink – How to Make a Heat Sink (DIY Guide) https://pick3dprinter.com/3d-print-heat-sink/ Mon, 29 Jun 2020 16:19:38 +0000 https://pick3dprinter.com/?p=6072 Table of Contents

Heat sinks are a very important component for keeping hot components cool. It can either include a fan or with the help of different other means, heat sinks ensure that the heating parts can go for long without burning out.

So, where we can employ the use of these components? Heat sinks are widely used in laptops, computers, lighting devices, airplanes, and many other devices.

We have already been engaging in a lot of traditional heat sink manufacturing process. However, the good news is that we can also 3D print a heat sink.

Doing so would help in optimizing the design of these components for better results. And, at the same time, these could be made lighter and smaller.

3D printing has become a great alternative for so many applications. There are niches, where 3D printing has replaced conventional methods with better outputs.

And, it is growing faster to make more changes to the already existing workflows within different industries. When talking about the small parts, such as heat sinks, the design specifications are very precise.

And, 3D printing excels are accomplishing parts that need accuracy and precision.

This is the reason why a lot of institutions and experts are researching ways to improve the overall output of heat sinks for making these even more efficient and reliable.

Let us find out how to 3D print heat sink and what are the various considerations one must take to achieve the desired outcome.

Types of Heat Sink

types of heat sinks

There are two standard types of heat sinks. One is the Active heat sink and the other is the Passive heat sink. The active heat sinks work with a power supply and often include a fan of their design.

On the contrary, passive heat sinks do not possess mechanical components. Usually, these are made of metals such as aluminum to utilize the concept of the convention for dissipation of heat.

back to menu ↑

Devices that Utilize Heat Sinks

Now that you have got an idea of what heat sinks are, lets progress to their usage. These components are widely available for varying applications.

Only within a computer, different parts make use of heat sink to stay cool and working. For example, CPU, video card, memory, hard drive, power supply, and many others.

Apart from that, heat sinks are commonly used for lighting devices, aircraft, etc.

back to menu ↑

Few Recent Studies to 3D Print Heat Sink

Heat sinks guarantee longer life for various devices including light fixture. Usually, these are crafted with the help of materials having high thermal conductivity.

For instance, copper, aluminum, etc. The role of these components is to conduct heat from the heated devices and divert it to their extremes. After the heat touches the extremes, it finally reaches the air flowing overhead.

The entire process is extremely crucial for the longevity of the devices that heat up on continual use. And, it is pretty evident that heat sinks are not just a spare part, but contributes hugely to the entire internal design of these devices.

Hence, researchers tried to find the potential of 3D printing in designing the better version of heat sinks that we already have.

In a recent study from two different contributors, a lot of facts were analyzed. Bringing the gist of all: can we 3D print heat sink? The answer is yes. But, what would it entail and how can we do that?

Experts from the USA, along with the researchers from Europe tested few designs to conclude that the 3D printed heatsinks aren’t just lighter and smaller but way more successful. The conventional heatsinks cannot have such benefits at all.

There are two projects working for the same cause, jointly proves that one can easily 3D print heat sink. One project was done at the Oak Ridge National Laboratory and the other was accomplished by the University of Tennessee in Knoxville.

One of the studies deems that the 3D printed aluminum heat sinks can not only match but can even supersede the thermal conductivity belonging to the standard heatsink made with aluminum.

The later has come up with genetic algorithms using the freedom of complex shapes possible with 3D printing for designing heat sinks. These are sure to perform better than their conventional counterparts.

3D Print Heat Sink: Benefits and Limitations

We do know that 3D printing has its own advantages and disadvantages, especially when printing with metals.

And, when it comes to heat sinks, where the performance depends a lot on the design of the component, we must look for the pros and cons of establishing a connection between 3D printing and manufacturing of heat sinks.

 

back to menu ↑

Benefits

As we know that 3D printing is an additive manufacturing technology that means that the material is added and not subtracted. Hence, when working with metals, and employing 3D printing, one could highly reduce the wastage of materials.

Another important reason for bringing 3D printing for manufacturing heat sinks is that it could help create complex designs that aren’t possible otherwise.

Not just that, it could also reduce the overall weight of these components making them lighter yet stronger and more efficient.

One can 3D print heat sink with fully dense parts and allowing the highest precision of internal features. This is not possible with traditional manufacturing.

In addition, 3D printing is a highly reliable choice. It may take the maker to fine-tune the design a few several times to get the right model in place.

However, once done, there remains almost no room for error. The 3D printer will design the component without any changes all the time.

This is a huge pro of 3D printing. And, in need of slighter change, one just has to change the 3D design and the parts would be enhanced as desired.

back to menu ↑

Limitations

We already talked a lot about the benefits. However, there are a few limitations as well. And, you must not ignore them.

Did we ever think why the lighting industry is still far behind when accepting 3D printing for heat sink manufacturing compared to the early adopters, aerospace, and automotive niche?

This is because 3D printing does provide better precision and offer lightweight results, but lacks speed.

Build times can be very high for printing with metals than it takes to build parts with plastic polymers. Plus, you may have to test multiple designs to finally find the one that suits your needs.

This would again complex the entire process, making the workflow tedious and time taking.

The other constraint is the cost of metal 3D printing. Not every industry can afford a 3D print heat sink. And, the mass production is also a question mark as of now.

How to 3D Print Heat Sink?

Before you decide to get a 3D print heat sink, you must come up with a suitable 3D design. And, there are certain tips you can always keep up your sleeves when working with metal 3D printing (discussed later).

Let us take an example of a DIY laptop heatsink to understand the 3D printing process.

Choose a Design or Build Yourself: There are various designs available on the internet for laptop heatsink. Laptop Stand by merthancioglu, 3D Printed Portable Laptop Cooler Pad and many other 3D designs are available online. You can either use any of these or create your own. You can also make changes to these designs for a few modifications.

Slice the Design: Use the 3D printer slicer software to create G-Code for the 3D printer. Using the slicer software, you must slice the layers for printing.

3D Print Heat Sink: You can feed the G-code to the 3D printer to start printing. If there are any settings that need to be done such as bed leveling or calibration, you must complete those prior to starting the print. After the printing completes, you can check the working of the DIY laptop heatsink all by yourself.

back to menu ↑

Points to Consider When Printing with Metal

As mentioned before, you must expect a fair amount of failures before you can perfect design, in case you are working from scratch to model a heat sink.

In the midst of all these, there are few usual pitfalls that turn designs into a nightmare. And, these can easily be excluded from your 3D printing process. Taking special consideration of these constraints, one can easily overcome a few of the common mistakes.

back to menu ↑

The Correct Wall thicknesses

Even if its metal, you cannot expect thinner walls to stay strong for long. These will collapse when printing under their very own weight.

Hence, one must ensure that the walls aren’t thinner than 0.5 mm. When doing so, a huge percentage of the battle against failed attempts will already fall in your favor.

back to menu ↑

Hollows

Every 3D printer is different with varying constraints. Hence, the limitations levied for holes may also differ. Apart from that, the limitation will also vary depending on the metals used, as well as the design of the parts.

If you go by the books, you must not include gaps under 0.5 mm. In case the holes and gaps are smaller, they may become susceptible to merging together with the sides and filling into the empty spaces.

Moreover, if you plan to design gaps greater than 10mm, you must use support to successfully accomplish the task.

back to menu ↑

Designing Overhangs

Once again, overhangs are tricky. And, if you include these in your design, you must not exceed a maximum of the maximum length of 0.5 mm. In addition, the structures facing downward must have chamfer having a concave shape (convex shape will also do the job).

back to menu ↑

Use of Support Materials

Usually, support structures serve two purposes. The first reason is to provide a base for hanging parts of the 3D design to the build plate. And, also for heat dissipation.

Hence, if there are any areas in your design that are below 45 deg. from a horizontal surface, it would need a support structure. This is the same along with all the metals you choose.

back to menu ↑

Working with Part orientation

You must know that with 3D printing, the parts created will have varying mechanical properties alongside different orientations. For instance, if you consider, the X and Y plane, the parts will showcase higher tensile strength compared to the Z direction.

This is why one must take extra caution when deciding the part orientation of the 3D model. It becomes even more important if you are printing a part that has to go through varying degrees of tension and pressure.

Not just that, the orientation also affects the surface finish of the parts. The face attached to the surface will end up with poorer surface finish when compared to the open surfaces, not in contact with the print surface.

Hence, if you are printing an object that needs to be impressive in certain areas, you must not forget to consider the part orientation. Moreover, the supports will also end up affecting the surface finish of the objects after removed. So, you must take care of that too.

back to menu ↑

The Conclusion

3D printing has proved every now and then that it is not going to stop. It will keep changing the way we work and design parts.

From medical to aerospace, technology has widened its application and will continue to grow further. There is no way, one can ignore the various perks that the niche has to offer.

This is why bringing 3D printing for enhancing the performance of heat sinks does not feel very surprising. Does it?

As we know that heat sinks are also a common component utilized widely for saving electronics and heated parts from failing.

In such a case, finding an apt design that could not only increase the efficiency of the overall device but could also be easy to design is the need of the hour.

Many researchers are already working on it. And, hopefully, we would find more industries, like aerospace and automobile, connecting with the cause sooner.

Until then, you can try to design and 3D print heat sink and explore the onset of a new future-ready to embark soon.

Who knows you may need to print something right away? This is when you would hate waiting for the manufacturer to ship the material to your address.

Also, the possibility of failed prints is even common among experts. Hence, the material that may look enough would not last long to complete the desired print with few failed attempts.

So, you must decide with your experience how much filament you must keep handy. Depending on your regular use, this could be an easy guess, isn’t it?

Right after you find yourself with an excess of filament that you may not be used in a week or so, you start worrying about the storage part.

Almost every filament can spoil because of the absorption of excess moisture. And, the problem is evident in the print results as well. So, ensuring enough space for your filaments is again very important.

When makers ignore the urgency of wrapping the filaments inside an airtight container, they often have to face issues such as poor layer adhesion, nozzle clogging, warping, and many others.

You can find various types of containers and can choose the one you like. Just ensure you do not leave your 3D printer material lying anywhere.

If you have been struggling to master the first layer adhesion, you must have tried masking tape. A lot of users turn to this option when not able to find that sweet spot on the build platform.

Not just that, it also makes it easier to remove parts from the build surface. On top of that, the masking tape protects the printer’s build plate from scratches and marks.

And, if you do know how much it helps, you must understand not having it around when you needed it. With all that said, you must know where we are pointing. Masking tape is the most common and crucial accessory that every user must keep in excess.

Alternatively, you can also use Kapton tape. This tape is even better with those materials that are highly susceptible to warping. Just remember to use the one with greater width. In this case, you would not need too many strips to cover the platform.

Increase Adhesion with Glue Sticks and Hair Sprays

One more accessory that we usually include in the list for improving bed adhesion is the PVA glue stick.

Although the option may fail to work with materials prone to excess warping, it contributes greatly to PLA, PETG, and other materials. Also, it is very easy to wipe off with water, when cleaning the bed to get rid of it.

You can directly apply the glue to the print bed and take it off using a wipe when done printing. Because of its ease of use, the product is popular among makers and 3D printing users.

Above all, it is cheap and very reasonable in its pricing. So, there aren’t any issues when keeping three or four more aside.

The hair sprays also work in a similar fashion. You just spray the product on the top of the print bed. This enhances the bed adhesion and it is easy to remove as well.

However, regular use of hairsprays without extra care for cleaning would eventually harm the print bed. One more tip, using hair spray with Kapton tape is a very effective solution for perfect bed adhesion for tricky materials.

You must be wondering, why? 3D printers already have build plates. Otherwise, how would 3D printing take place? However, not every print bed offers the desired first layer adhesion.

As mentioned above, budget printers often come with this limitation. But there is always another way out of every problem.

By choosing a glass plated print beds, you can astonishingly enhance the first layer adhesion. Some materials may not have problems with a simple one that came along with your 3D printer.

So, you can keep using it. And, swap it with the updated build plate when needed. This way, you can also increase the self-life of these platforms. Also, glass plates provide a better surface finish. Hence, you can ultimately achieve better print quality.

Mask for Preventing Dust

Flexible Masks 3D Printed Face Mask

Are we not always advised to work in a well-ventilated room when 3D printing? There is a reason for this. When you heat plastic-based materials, it emits noxious and irritating fumes.

Depending on which filament you use, the emission differs. Some release excess of these gases and others may not do so at all.

These gases could be highly dangerous if inhaled with prolonged exposure. Those filaments that are free from the emission of harmful gases do release microparticles when heated which may pose a threat to the respiratory system.

Looking at all these challenges, and understanding that not every 3D printer comes with an enclosed compartment, it is important to include the dust mask in the list of essentials.

These dust masks are a huge requirement for those working very closely around the 3D printers. Even with a ventilated room, you must take extra precautions to keep yourself safe.

You can take these off when leave the room where printing is in progress. However, do not forget to put it on again when you re-enter the workshop.

Build Plate Sticker

Build Plate Sticker

Need extra adhesion? The build plate stickers are yet again a very awesome alternative for 3D printing users. The best part is that the stickers could accommodate almost every filament available.

Hence, you do not have to work in different directions when printing materials with varying properties.

To use the stickers, you just have to stick these directly over the print platform. And, after a 3D printing project is over, you can take it off just like that.

Post-processing to perfect the finishing of the parts would definitely help enhance the looks of your models. And, if you are already putting so much effort into 3D Print an object, why not work a little more to perfect it completely.

The sandpaper is the first step before you plan to polish or paint your printed part. So, keeping them in stock is not just an option but essentially important.

Super Glue and Acetone

3d printing acetone

You can only go on counting when thinking about the usage of super glue when 3D printing. It can repair parts that are broken, fill gaps, connect two 3D parts together, etc.

It is very effective and must be on the list of must-haves. The 3D printer supplies aren’t complete without including it in the list.

Similarly, acetone is also a bonding agent that works best with ABS. It not only provides amazing bond strength but could help remove the difference at sites where the parts connect together. Hence, it also provides a better finish to the parts.

Varying nozzle diameter creates a huge difference in the print quality of the parts. For instance, the smaller diameter offers high precision and a negligible layer difference.

However, the bigger one would not be that great with hiding the layer difference. On the other hand, the bigger ones can create models faster than the smaller ones.

So, depending on the need for the 3D printing project, you may have to swap these nozzles from time to time. Now you know why these are important to include in the 3D printer supplies.

Cleaning Tools

3d printing cleaning tools

You must ensure that the nozzle and extruders are free from clogging. Or, the problem could take a difficult shape. You may find the filament struggling to leave the print head.

Or, they may not come out at all. And, this will create a problem when printing. Would you like that to happen?

After every print, you must clean your nozzle. This is why the nozzle cleaning tools are necessary.

Tool Set for Carving the Printed Parts

3d printing carving tools

There are certain parts that have finer details and uses a lot of support to stay up when printing. Hence, these parts may not turn out to be as smoother as those without fine details. Hence, you must keep carving tools along with you to give these parts the necessary makeup.

The first layer adhesion could become messy when trying to remove 3D parts from the print bed. And, you will need a set of tools to get these out of the build plate.

The most popular and easy to use option is the set of spatulas. These are simple to work with and cannot be ignored when working with FDM 3D printers. These are the most essential. So, never forget to include these with the 3D printer supplies.

The Conclusion

Why do we need to stress so much on the 3D printing accessories? Don’t you want to create flawless parts without looking for supplies that may not be available when needed? We all want that, isn’t it?

Hence, one must take an extra case when choosing among the different 3D printer supplies and selecting the ones that are very much needed. Or else, you may never know how far your objects can go in terms of perfection.

Wax 3D Printer – How They Work & Which to Choose? https://pick3dprinter.com/wax-3d-printer/ Sun, 28 Jun 2020 01:12:52 +0000 https://pick3dprinter.com/?p=6042 Table of Contents

Amongst the many names that come under the title “3D printing technologies”, a few offer an option of wax 3D printing. One can print models by selecting wax as a material.

Although they call it wax, the material is not particularly natural wax, when in use. The material which is used with a wax 3D printer differs in terms of properties owned by the natural wax.

Fused Deposition Melting, Stereolithography, selective laser sintering is not as popular with wax 3D printing, as much as material jetting is.

This technology is not only the most popular one with wax 3D printing but also is the most optimal way in which one can print using wax.

It is to be noted that wax 3D printing is a very associated term with jewelry products. Having said that, you might have some curiosity bulbs lit in your head when you would have come across some terms.

Material jetting, wax 3D printing, and its association with jewelry products and how do wax 3D printers work? Are the topics that we would be covering in this article one by one.

We would also find out a few of the most trending 3D wax printers that have been able to impress users with its efficiency and accuracy of results.

Outline of a Basic 3D Wax Printing Process:

A 3D wax printer has a similar workflow as any of the other 3D printing processes. Starting with the 3D design, it goes for a layer to layer production.

And, in the midst of it, what brings a difference in the working of these processes is the selection of material, the technology used for creating each layer, and few others.

So, let’s find out how the 3D wax printing works. And, what are the different steps involved in this process while a few of the standard ones remaining the same?

  • In the first and foremost step, we must create a 3D model of the object we wish to 3D print.
  • Once the 3D model is created with the help of the CAD software, its printing process starts layer by layer. In the case of 3D wax printing the process that is optimal and used the most, is material jetting, about which we will learn in the section below this one.
  • After the model is ready, it progresses towards investment casting. In the first step of investment casting, we create a mold around the model.
  • Later, the 3D printing object melts and leaves a space in the mold that corresponds to the final object.
  • Lastly, space is filled with molten metal. Once it sets, the mold is broken to achieve the desired part.

Now that you have a basic outline of how 3D wax printing process, the next step that you should read about is material jetting. Wax 3D printers are based on material jetting.

What is Material Jetting?

Like other printing processes, this one too starts by pouring resin into the material container. Like in SLA 3D printing, in material jetting too, thermoset photopolymer resin is heated to attain particular viscosity.

The main components of a printer that works using material jetting are a) print heads. 2) UV light sources. 3) build platform and 4) material container.

Here the arrangement is that the UV light sources and print heads are suspended along a carriage which is on the X-axis.

As the carriage along this axis starts its journey across the build platform, the print head begins to particularly pour out or, so to say, jet tiny resin droplets.

With the print heads, the UV light sources follow. The picture below depicts material jetting in 3 parts i.e. a) initiation, b) at the midst and c) when a product is completed.

The process involving the creation of the first layer is repeated for other layers until the product is completed. Material jetting is eccentric in the way that it offers line-wise deposition.

This is something that’s not offered in FDM, SLA, and SLS as all the three offer point-wise deposition. Now that you have an idea of the technology, based on which 3D wax printers work, let’s get to know why this is so popular and associated with jewelry products.

Why are Wax 3D Printers Used to Make Jewellery Products?

The manufacturing of jewelry products is a very detailed topic for obvious reasons. The cost of raw material is very high than others makes this technology a bit expensive than others.

Because of the involvement of high-end precision, material jetting based 3D wax printers are used to produce jewelry products like no other.

The secret lies in the detailed mold that is produced by using material jetting. Unlike other techniques, the resin here is poured drop by drop, constituting the complete line.

To produce a gold ring, jewelers must design a mold where the liquid material is poured that then solidifies to take the desired shape of the ring.

This high-end detailing is only possible by material jetting. As you have already seen the basic outline of 3D wax printing, you have an idea about how the printing process works inside a 3D wax printer.

Once the model is created inside the 3D printer, wax 3D printers can be used to produce a wax model of the ring. After the completion of this process, those models are placed into a liquid solution and the soluble part dissolves.

After this the material solidifies, the mold heats to the point where the wax model starts melting and leaves the space for gold, silver, or platinum, whatever the choice is.

The final step is to inject the material, jewelry of which you wish to make. This is how a 3D wax printer works based on material jetting to produce jewelry items.

If you have read about other 3D printing processes such as FDM, SLS, SLA, you’d be able to differentiate material jetting from them quite easily.

By now, you certainly are now quite familiar with the process that goes inside a 3D wax printer that produces some of the most beautiful jewelry that you have seen.

Hence, now it’s time for the recommendation of some of the names of those wax 3d printers that work in practical terms to give shape to the most beautiful imaginations of the users.
