Carbon RPU 70
A tough all-purpose engineering grade material that comes in black.
What is Carbon RPU 70?
RPU 70 Rigid Polyurethane is manufactured through Carbon’s DLS (digital light synthesis) process. It is a tough all-purpose engineering grade material that comes in black and can be categorized as an ABS-like materials. Ideal part sizes for Carbon materials are 5 in. x 5 in. x 5 in. or less.
Applications
- Complex designs that are challenging to mold
- Production parts
- Durable end-use components
Key Benefits
- Toughness
- UL 94 HB flame resistance classification
Related Materials
- Carbon FPU 50

Carbon DLS Finishing Options
Unfinished
With unfinished, you get varying aesthetics based on build orientation. Dots or standing nibs remain evident on the bottom of the part from the support structure remnants.
Natural Finish
With natural finishing, you get varying aesthetics based on build orientation. Standing nibs are sanded flat.
