Plastic was a very important invention of material science. Any material that is made of synthetic or semi-synthetic compounds and has a property named malleability can be termed as Plastic.
After being useful in a wide range of applications, during traditional manufacturing methods, Plastic was then tried and tested for making products using 3D printing technology.
Coincidentally, Plastics were found to be very useful in making parts and functional prototypes using 3D printing technology. Just as they were in manufacturing with traditional techniques.
In this article, we are going to share information about 3D printing plastic costs.
Amongst the synthetic or semi-synthetic compounds, the use of former ones is more in the market than the later ones.
The use of plastic is almost in every kind of 3D printing technology.
You may get to see the use of plastic a lot in filaments that are used to print parts or functional prototypes using FDM 3D printing technology.
Plastics are also found to be used in powdered form with Material Jetting 3D printing technology as well as Multi Jet Fusion 3D printing technology.
We are going to start listing down one by one of the most popular plastics that are converted into the material and are used for making parts and functional prototypes using one of the above mentioned 3D printing technologies.
With that, we are also going to share with you the 3D printing plastic cost.
So that you can get an idea about one of the most important factors while planning a budget for a 3D printing project i.e. The material cost.
Popular 3D Printing plastic Cost
By merely changing its form, the same plastic can be used in printing parts or functional prototypes using different 3D printing technologies.
In its solid form, plastic is used to make products using FDM 3D printing technology.
The liquid form of plastic is employed with SLA or SLS 3D printing technology for making high-quality parts and functional prototypes.
Whereas the powdered form of plastic can be used to make products using powder bed fusion 3D printing technology.
Undoubtedly, ABS is one of the most popular plastics finding a wide range of applications due to its properties.
It is one of those materials that is used for producing bodywork of cars, as well as mobile phone cases.
This thermoplastic contains a base of elastomers that are based on polybutadiene, which makes it even more flexible than other options of plastics.
Along with making ABS more flexible, polybutadiene also makes it shock resistant, and hence its use is seen in the bodywork of cars.
Apart from FDM 3D printing technology, ABS finds its use with powder bed fusion technology and SLA which makes it a versatile plastic compared to others which can only find their use in not more than one technology.
While 3D printing ABS one needs to take care of the temperature range 230 to 280 degrees Celsius, which is known as the best temperature range for printing this material.
The toughness of this material makes it capable to withstand a temperature range from -20 to 80 degrees Celsius easily.
The criticism that this material has faced is in recent times with the increasing awareness of biodegradable materials in search of a more sustainable material.
ABS contracts with air so it is recommended that the printing platform must be heated for preventing warping.
ABS is known to print easily in closed environments and for the same reason, it is recommended to use ABS with a closed chamber 3D printer.
The average price of ABS is around $15 to $20 per kilogram. While purchasing ABS do look for tolerances, the lesser the tolerance of the material, the more should be the price.back to menu ↑
ABS and PLA can be called the Santa and Banta of the 3D printing industry. The 3D printing plastic cost of ABS and PLA is as competitive as their use is in the industry.
PLA is an abbreviation for polylactic acid. There is an inherent benefit that PLA has over ABS and this point has to do with the point that ABS faces criticism for, from the 3D printing market.
PLA is biodegradable and also the easiest material to 3D print with. There will hardly be a 3D printer that is not compatible with PLA 3D printing.
Although PLA’s limitation is that it shrinks after it is 3D printed into a part or functional prototype.
Unlike ABS, PLA does not require any 3D printing platform for printing the material.
Also, PLA prints at a much lower temperature range than ABS. The temperature range which is considered a comfortable one for PLA ranges from 190 to 230 degrees Celsius.
Because of its high cooling and solidification speed, PLA becomes a difficult material to manipulate into some shapes which has more curves. But, because of its availability in various colors, PLA is a very suitable material in FDM 3D printing.
PLA would probably be the least expensive product on this list.
Although the average price of the material falls in the same range as ABS, the lowest price option available for this filament may even fall beyond $15.
But overall standard brands are known to fall between 3D printing plastic costs of $15 to $20 per kilogram.back to menu ↑
Also known as glycolized polyester, PETG is a thermoplastic that is widely used in the additive manufacturing market and it should be because chemically it is a hybrid developed out of the two most popular materials in the 3D printing market i.e. ABS and PLA.
PETG is an amorphous plastic that can be 100 percent recycled. Colloquially this material is also known as PET.
If it were not a glycolized polyester, it would have been a more brittle and fragile material.
Adding glycol to this material gave it a sort of flexibility that it currently possesses.
PETG replaces ABS in applications that need the material to have more strength and temperature resistance than ABS.
Although having more sincere characteristics than ABS, its price does not change much from the price range of ABS.
The 3D printing plastic cost average price range of PETG is $16 to $19 per kilogram.
Mainly PETG finds its application when employed with FDM 3D printing technology to make parts and functional prototypes.back to menu ↑
Usually, the parts and functional prototypes made from Nylon are made using SLS 3D printing technology.
They are created by putting into the process a fine, white, granular powder.
Although when it comes to FDM 3D printing technology, Nylon shows some compatibility with its variants.
Chemically polyamides are the only material to show an immense amount of compatibility when it comes to making products that come in direct contact with food.
The semi-crystalline structures of polyamides make sure they have a good balance of chemical and mechanical characteristics hence offering a good amount of stability, rigidity, flexibility, as well as shock resistance.
High quality of polyamides finds them application in the field of making gears, parts for the automotive industry, robotics, as well as the medical industry and injection molds.
Cable ties are areas where Nylon is regularly employed.
The 3D printing plastic cost average price of Nylon ranges from $50 to $73 per kilogram.back to menu ↑
PEEK, PEKK, Ultem
The evolution of 3D printing technology from a perspective of thinking to practical application finding technology that can compete with the traditional forms of manufacturing has enabled the growth of 3D printing materials such as PEEK, PEKK, and Ultem.
These are high-performance filaments that resemble the characteristics of metals.
They are distinguished from one another because of families such as polyaryletherketones (PAEK) or polyetherimides (PEI).
They have high mechanical and thermal resistance which let them comfortably being used for making parts that metals are used, but they steal the show by being lighter in weight.
So, you might often find these materials in the aerospace, automotive as well as medical sectors.
Indeed, you would need a 3D printer that is capable of withstanding temperature ranging in the range of 350 degrees Celsius.
Whereas a heated build plate that can withstand at least 230 degrees Celsius.
But when you look at the outcome of parts or functional prototypes, it is worth it.
And slowly with the development of materials, these three are also finding application with SLA 3D printing technology.
A typical Ultem filament’s 3D printing plastic cost of the spool is $80 per kilogram.
The price is not different for 1.75 mm, from 2.85 mm.back to menu ↑
Because of its good resistance to temperature, Polycarbonate finds application in many engineering products. It is able to resist undergoing any physical resistance up to 150 degrees Celsius. The only limitation that makes polycarbonate a little less favorable than ABS, PLA is its ability to absorb moisture from the surroundings, because of which when you buy a filament of polycarbonate you need to pay strong attention to the storage part of the filament. It should be stored in airtight containers.
The additive manufacturing industry is in debt to polycarbonate for giving its customers strength and transparency. Polycarbonate has a much lower density than glass, which makes it particularly interesting for designing optical parts such as protective screens or decorative objects.
The 3D printing plastic cost average price of polycarbonate filament ranges from $30 to $93 per kilogram. And it is known that most of the 3D printers that allow printing with polycarbonate use 1.75 mm filament which is fifty percent more than standard PLA.back to menu ↑
Here is a material that has similar properties to ASA, but even greater resistance to ultraviolet rays.
And for this reason, it finds application in places where ABS cannot be used because of not having such strong resistance, such as the exterior of homes.
The problem of warping which is evident in ABS is also evident in ASA and hence when you are printing using ASA, you are advised to print parts and functional prototypes using a heating bed that is able to provide you with uniform heating.
Extra care, however, must be taken while printing this material due to styrene emissions which are not a matter of concern when one prints using ABS.
ASA is majorly used for outdoor applications not only because it has UV resistance, but also because of being moisture resistant and electrically insulating.
The 3D printing plastic cost on average for an ASA spool is found to be ranging from $30 to $50 per kilogram.
There is no difference in price when you choose a spool that has a diameter of 1.75 mm and 3mm, which is interesting, isn’t it?
The 3D printing industry majorly operates on FDM 3D printers and FDM 3D printing technology which needs a filament for producing a part or functional prototype. A
lthough the situation is changing and now even SLA 3D printing is growing, but it will take time.
Till then, filament remains the main source of material required for 3D printing a part or functional prototype.
Hence you might notice the use of plastics more in making filament spools, than in making liquid resins or powdered form material which are a source of 3D printing a part or functional prototype using SLA or powder bed fusion 3D printing technologies respectively.
The 3D printing plastic cost of the materials mentioned above are subject to change from brand to brand based on the raw materials used for constructing a filament or a resin.
You might have noticed that for the same reason we have mentioned the price range and not the exact price of that material.
This is to give you an idea of material costs which is one of the most important parameters while calculating the cost of the complete 3D printing project for printing a part or functional prototype.
Material costs, along with operating and labor costs constitute the final cost of 3D printing a project.
