3D print materials
Below you will find all the materials we offer.
They are arranged according to the possible printing technologies: SLS, FDM and SLA.
Quickly see which material seems interesting to you and find more information under each section separately.
SLS
PA-11
Polyamide-11, PA11 or also called nylon-11, is made from the oil of the castor tree. So it is a completely organic product.
This material is impact resistant and strong, but also very flexible if you take this into account during the design.
A big advantage is that it does not splinter when broken. This way you don't have to worry about damaging other parts during a test.
The resistance to harsh environments is also a major asset for nylon-11. The impact resistance remains almost identical down to -40°C and the material can be used in temperatures up to 150°C without any problems.
Most acids, salts and bases have no effect on it.
Are you unsure about the choice of materials for your project and do you have high requirements? Chances are, PA11 will work for you.
Not only is PA11 organic, it is also biocompatible. This means that it can be used to be in direct contact with the skin. In addition, it can be sterilized in an autoclave, which makes it increasingly popular in the medical sector.
This material already has a foothold in the automotive industry. Its high impact resistance and resistance to mechanical stress make it very suitable for moving parts in important places. Due to its chemical resistance, you don't have to worry about deterioration over time in a demanding situation like a car.

FLEX TPU
TPU is like no other material we offer. It is extremely flexible, only breaking at an extension of more than 30 times!
This is possible in temperatures between -40°C and 70°C. And all this while it is also resistant to all kinds of chemicals such as gasoline, butane, carbon monoxide and ethyl alcohol.
In addition, it is also an excellent electrical insulator.
Flex TPU can be found as insulation around cables, because of its extreme flexibility and electrically insulating properties.
This material is also extremely suitable as a sealing ring. Its chemical resistance allows it to come into contact with your application and its high elongation allows you to apply enough tension that nothing escapes.
A flexible interface is also always interesting for robots. For example, you can use TPU for the suction cups on an industrial line or for the grippers of a robot arm.
- Tensile strength: 9.94 MPa
- Elongation at break: 3319%

PETG
PETG is a variant of PET, which you have undoubtedly heard of. PET is used in PET bottles, fleece and the vast majority of food packaging. The success of this material is no mystery, it is strong, light and impact resistant.
PETG builds on this with a glycol group. This ensures that the material is less brittle and therefore also has a greater tensile strength. In addition, this plastic is resistant to oil, fats, acids, salts, solvents, etc., so that it can be used in harsh environments. PETG also has little effect from UV light.
In 2016 and 2020, research was published about an enzyme that can completely break down PET, making it even more interesting to recycle. Something that is already a major advantage of PET.
Due to its extremely good tensile strength compared to, for example, ABS, this material is better suited for industrial tools and parts. Certainly when they are used in an environment where many chemicals are present, as is the case with many machine installations. In addition, PETG is self-extinguishing, which can be very useful in the same situations.
This is also a very good choice for prototypes of packaging material that will later be manufactured in PET. The properties of both materials are close to each other and the advantages of 3D printing for prototyping are immense compared to having custom tooling made.

SLA
Gray Resin
Our gray resin material is the go-to material if you are looking to print SLA. The gray color shows details very nicely and because of the super fine layer structure you can hardly see that it is 3d printed. It has a better tensile strength than most FDM materials, because it has a better adhesion in 3 dimensions due to the printing process. Where FDM materials adhere layer by layer and fail more frequently between layers, SLA parts do not have a preferred orientation after their post-treatment.
However, this material is not a thermoplastic and can therefore no longer be heated for deformation. It is also more brittle than most FDM materials, making it easier to scratch and break in the event of a fall.
The best everyday comparison in terms of strength and behavior of this material is plexiglass.
The best applications for a material like this are objects that will experience little force in their day-to-day use. Due to its fragility, it is not immediately suitable for mechanical pieces or moving parts.
Gray resin, however, shows its strengths when it comes to displaying very small details such as in miniatures. If you are thinking of making a mold, this can also be an excellent choice as a master mould. The mechanical properties of the material are not essential here, but it mainly concerns the appearance of your piece.
- Tensile strength: 65 MPa
- Elongation at break: 6.2%
- Heat deflection temperature: 73°C
Clear Resin
Clear resin is a beautiful material where you can hardly see that it is 3d printed due to the super fine layer structure. It has a better tensile strength than most FDM materials, because it has a better adhesion in 3 dimensions due to the printing process. Where FDM materials adhere layer by layer and fail more frequently between layers, SLA parts do not have a preferred orientation after their post-treatment.
However, this material is not a thermoplastic and can therefore no longer be heated for deformation. It is also more brittle than most FDM materials, making it easier to scratch and break in the event of a fall.
Gray and clear resin are identical in terms of mechanical properties, but where gray resin shows the details very well, clear resin has the advantage of transparency. If you choose clear resin with an order, you get the choice to add an extra transparent post-processing. The piece always remains slightly yellowish, but exchanges its translucency for transparency.
The best everyday comparison in terms of strength and behavior of this material is plexiglass. The degree of transparency depends on the geometry.
The best applications for a material like this are objects that will experience little force in their day-to-day use. Due to its fragility, it is not immediately suitable for mechanical pieces or moving parts.
If you are looking for a piece that is a real feast for the eyes, then clear resin is a clear choice. The transparency of this material has something enchanting to look at. Because it is printed with SLA technology, layer lines are also almost invisible, as you can see in the image above.
- Tensile strength: 65 MPa
- Elongation at break: 6.2%
- Heat deflection temperature: 73°C
High-temperature plastic Resin
This high temp resin has its greatest asset in the name; this plastic can withstand temperatures up to 238 °C without any problems. This number is obtained by a standardized test in which a pressure of 0.45MPa is applied. The temperature that we measure when the piece yields 0.25mm is the 'heat deflection temperature'. Pieces made of this material will therefore not deform quickly under a high temperature.
Furthermore, it has similar properties to the other resins that we 3d print. Quite a high tensile strength, which makes it very strong in all directions, but it is also brittle and does not have a great elongation before breaking. This means that a part in this high-temperature plastic will break with a nice fracture if it falls sufficiently high.
The applications for this plastic are quite obvious. If you need a custom piece that will keep working (without melting) in a kiln, this high temperature plastic is the obvious choice.
Think of a process in which something has to be baked in an oven, but must not touch the bottom of the oven. A part that lifts your product and does not experience a problem with the temperatures itself is a perfect solution.
The properties of this material do not immediately appeal to other applications. It is also more expensive than other options when it comes to temperature.
- Tensile strength: 51.1 MPa
- Elongation at break: 2.4%
- Heat deflection temperature: 238°C
