With such a great variety of 3D printing materials to choose from, it can be difficult and confusing to find the right one. But don’t worry — in this post, we’ll discuss all major 3D printing materials and provide you with small previews and links to learn more about each.
We’ll talk about all 21 materials and more than 100 finishes that we offer here on i.materialise now! To make things easier, we’ll split this article into the following three sections:
- Plastic 3D printing materials
- Metal 3D printing materials
- 3D printing in other materials
Plastic 3D printing materials
For plastic 3D Printing, the most popular choice is Polyamide — a strong and flexible nylon plastic. Its Natural color is white, but it can be dyed in several colors. Its surface is somewhat rough, but it can be smoothed out. The printing option — laser sintering and Multi Jet Fusion — use powdered polyamide, enabling designers to use it for interlocking and moving parts (i.e., creating a chain).

Polypropylene
3D-printed Polypropylene has properties similar to the injection-molded kind, and the natural finish has a sandy, granular look in a translucent off-white color.
Another popular plastic choice is based on resin. Resin 3D prints are made from a liquid photopolymer cured with UV light during the stereolithography 3D printing process and feature a smooth surface. Resin printers can be huge — our biggest printers can print up to 2,100 millimeters! With five different resin options, you’ll find what you’re looking for, whether that’s prints with an extremely high level of detail or our more affordable option: Gray Resin.

Mammoth Resin
Our Mammoth Resin prints are available with a natural finish or spray painted in the following colors:
Standard Resin
Natural, basic
Natural with support
By opting for this finish, you’ll receive your part with the support structures still attached. You can remove them yourself with tools and sanding paper.
Transparent Resin
Natural
Color
By adding a small amount of paint to the varnish, we can create a colorful look in white, yellow, red, green, blue, gray, and black.
ABS
Our final plastic material is ABS. This material will give you a print that is strong and accurate. ABS is very useful for functional applications because it matches 80% of the properties of real injected production material. However, the surface quality of the models produced with this material is rough in comparison with other materials.
Metal 3D printing
All of our metal materials are printed from their powdered forms. While Titanium is laser-sintered directly, Steel prints are created with the use of a binding agent and curing oven.
Aluminum
Aluminum is a great option for strong, lightweight parts. You’ll notice a subtle sparkle caused by the presence of silicon in the alloy.
High-Detail Stainless Steel
If you’re looking for an extreme level of detail, High-Detail Stainless Steel is probably what you’re looking for.

Titanium
Titanium is the strongest 3D printing material out there. It has a matte look and comes with an upscale price.

Our precious metal models come in silver, gold, brass, bronze, and copper. Most of these metals have several finishing options.

Bronze

Copper
Although we polish copper models magnetically and by hand, the material is very sensitive to oxidation. By nature, copper has a reddish color but it will tarnish and turn green (verdigris) when it starts to corrode.
Gold
Gold objects can be created in 14k and 18k and in yellow, red, or white gold.

Silver comes in five different finishes, including our ‘antique finish’.

3D printing in other materials
Multicolor
Multicolor is the only material that enables you to print models in more than one color. Models made of multicolor are constructed from a fine, white, granular sandstone powder. The interior of the model stays white while coloring print heads ‘paint’ the exterior of your model.
Rubber-like
3D prints in Rubber-like are highly flexible and printed in Multi Jet Fusion machines. The surface of this material is fine and granular. Technically, Rubber-like is a plastic material; however, we put it in the ‘other’ category to highlight its extraordinary material characteristics.
