Material
Ultrasint TPU 90A-01
Ultrasint TPU 90A-01, a thermoplastic polyurethane, combines durable elasticity with good wear and abrasion resistance, making it ideal for prototypes and end-use applications that require good shock absorption. Developed for Multi Jet Fusion printers, this fully functional material has high elongation at break, excellent surface quality, and offers a high level of detail.

Finishing degrees
The right finish can transform your print into a product. Explore the post-production finishes we offer for this material. If you have any questions or special requests, get in touch with us.
Normal
- Loose powder removed
- Sandblasted
Extra smooth
- Loose powder removed
- Sandblasted
- Parts are chemically smoothed by being placed in a chamber with a vaporized solvent
- This process mainly smooths the outside of your part; the inside may be less smooth
- As the polishing process removes material from your part, you should foresee a minimum wall thickness of 2 mm
- Thinner walls (1 mm) could deform and small surface details may disappear
- Edges will be rounded and your part will become less ’crisp’ once smoothed
- Parts need to be hung up for this process; holes in the design can be used or a hook which is cut away after smoothing
- As residue from the smoothing process can accumulate in sharp inside corners (i.e. bridging effect), we advise adding chamfers to all corners
- This finish is possible for parts with maximum dimensions of 360 x 274 x 375 mm
Color dyed
- Loose powder removed
- Sandblasted
- Parts color dyed by being submerged in a bath containing black pigment
- Due to the unique nature of the production process, e.g. in terms of parameters, build position, and light deflection, as well as differences caused by post-processing, color intensity may vary
- This finish is possible for parts with maximum dimensions of 150 x 150 x 150 mm
Spray paint A-side/2-side (dead matte, 10% gloss) Black
- Loose powder removed
- Sandblasted
- Dead matte paint (10% gloss) sprayed on the A-side/both sides. Painted according to RAL specifications
