When you land on the homepage of the manufacturer’s website you get to know that Union Tech is not just into manufacturing 3D printers, but also into materials as well as software solutions.

In this article, we are going to look at the industrial 3D printer that currently offers the highest build volume amongst other 3D printers manufactured by Union Tech.

Features

ADVERTISEMENT

Apart from offering a huge build volume, there are some other points which also you must lay your focus on while buying this 3D printer.

Because these are the features that stand out not only in the price range that the printer falls into but generally in the list of 3D printers, which are based on the same 3D printing technology that the 3D printer belongs to.

So, what good section to begin our journey of knowing in-depth about the printer than its Features?

Convenient assembly and disassembly of the platform

The build platform is a part of the printer which is supposed to be maintained with complete care for ensuring the long term success of the printer.

The manufacturers of this printer have therefore given a convenient assembling and disassembling of the build platform that lets you take away the parts or functional prototype from it while you are doing the post-processing.

You can also clean the complete build platform to ensure that the other part which you will then manufacture on the same build platform can be done easily.

Granite recoater frame for enhanced recoating stability

While the printing process is going on, there are a lot of parts of the printer put to work.

There is the laser source which helps in curing of each layer after it is spread over the build platform, there is the nozzle system which has to move against the gravity after printing the layer, there is the print head controlling the nozzle, and what not!

To control all these parts of the printer safely, during the printing process, you need a solid frame.

Granite is a material that is known for being stable and rigid and because of that very reason; the manufacturer of this printer has made the frame of the printer using it.

So, the users do not have to undergo any difficulty while the printing process is on.

This is also an important point that contributes to the accuracy of part or functional prototype that is manufactured in the printer.

For if the frame of the printer is unstable, so would be the printing and hence leading to the production of parts or functional prototypes that are not dimensionally accurate.

Automatic control of surface level and processing parameters

Sensors inside the printer take care of points wherein without human intervention the message is conveyed to the part of the printer that needs that message.

This includes points such as loading and unloading of the resin, the automatic bed leveling, support structures according to the design file of the part or functional prototype, and more.

When all of these parameters are driven automatically according to the programming done by the manufacture, it increases the efficiency of the complete process.

So you are longer left with the headache of taking too many factors into account, all you are left to manage is the 3D design file.

And hence there is very little chance to make mistakes or flaws in the system because as the golden rule of manufacturing states, the lesser human intervention, the lesser the chances of flaws or decrease inaccuracy.

Closed-loop control strategy

The manufacturers of this printer have made a closed-loop control strategy for parts and functional prototypes such as platform improvement.

This is very useful when you are doing batch production or producing different parts and functional prototypes one after the other.

For laser power also the printer uses a closed-loop control strategy, wherein after a layer of the part or functional prototype is printed, the work of the layer is automatically switched and the layer is cured.

The material level indication is another factor wherein the manufactured has used a closed-loop strategy.

These are areas wherein the manufacturers have fixed indication levels at some level and then when those levels are achieved you are notified to make sure that you change the material when needed for the printing.

Even for temperature as well as vacuum, the manufacturer has used a closed-loop strategy.

First Impression

Uniontech RSPro 800 3D printer

There are photographs of the printer posted online that reveal different sides of the printer based on which our first impression is based.

The front view of the printer makes it look like one of those time machines that you see in the movie.

The front is divided into two parts, the upper and the lower, wherein the upper is transparent enough for you to get a glimpse of what is happening inside from outside.

The lower is again divided into two i.e. the left and the right.

When you have a closer look at the front end of the printer you are able to see the small aisle type body on the right which contains a display screen with some buttons.

The right read end of the printer consists of doors that are typically used for storing 3D printing materials in industrial-grade 3D printers.

Whereas the left rear of the printer contains a window that lets you peek into the print chamber for ensuring whether everything is happening as you intended it to happen and the part or functional prototype is getting printed.

There is a picture that is taken from the top showing you how there are doors on the top of the printer body which can also open up to tell a different story.

Setup

Like most other industrial 3D printers, this one too comes completely assembled.

You need to be an expert in operating SLA 3D printers to operate this one.

However, it is advisable not to directly start printing, rather read the manual and about the parts of this printer for ensuring a safe and secured and intended 3D print.

To help you out with the doubts about parts and first print, there is a product portfolio, a Contact Us tab on the webpage dedicated to the 3D printer on the manufacturer’s website.

Printing Type/Cost

The best way to know how much or less is the cost of printing one part or functional prototype using one 3D printing technology than the other is to print the same part on printers based on two different technologies.

When done so, printers based on SLA 3D printing technology account to be more costly than FDM 3D printers.

The reason being; the use of laser source in curing the part or functional prototypes in the SLA 3D printers.

This printer is also based on SLA 3D printing technology so you would have to use liquid resins instead of filaments as you do in FDM 3D printing technology.

Print Quality
