TM 79 is the material of choice for the application of high toughness and durability parts. TM 79 performance is analogous to PA 12, with excellent low shrinkage and high impact strength. It is an ideal material for rapid prototyping and small batch test parts processing such as wind tunnel testing, electrical enclosures, tooling fixtures and automotive interior and exterior trim. Based on LEAPTM nano- release technology, the components are formed quickly, post-processing is easy, and it has excellent dimensional accuracy and detail resolution.
