When one needs a material to build durable concept & show models, prototypes, tooling & fixtures, and low-volume production parts, then the resilient and high-performance Fused Deposition Material (FDM) material, ULTEM , is a good candidate.
The ULTEM material allows one to work more iteratively, test more thoroughly, and move confidently and efficiently from prototype to production.
ULTEM is a flame retardant high performance thermoplastic material. This FDM material is ideal for functional and end-use parts that require high strength-to-weight ratio and its FST (flame, smoke, and toxicity) rating. ULTEM widely used in the aerospace, defense and automotive industries.
