3Dresyn Nylon-like Polyamide Tough Engineering Resin

3Dresyn® Nylon-like is a high-performance photopolymer engineered to replicate the mechanical behaviour of polyamide (nylon), combining toughness, moderate flexibility and high impact resistance while eliminating the typical water absorption associated with conventional nylons. The material exhibits semi-rigid behaviour with pliability at low thicknesses and good shape recovery. It also provides excellent adhesion to a wide range of substrates and incorporates bio-based content from renewable sources. It is available in HV (higher mechanical performance) and LV (lower viscosity) versions for compatibility with SLA, DLP and LCD systems.

Intended for professional use in vat photopolymerization (SLA, DLP and LCD) additive manufacturing.
Final suitability of printed parts must be validated by the user according to the specific application, processing conditions and applicable regulatory requirements.
