UMA 90

Urethane Methacrylate


UMA 90 is a one-part rigid resin similar to conventional SLA resins it can be printed quickly and cheaply to prove out designs or to make production parts for applications with less-demanding requirements. It is well suited for producing manufacturing jigs, fixtures, and general-purpose prototypes.
