3Dresyn PMMA-like Acrylic High-Stiffness Transparent Engineering Resin

3Dresyn® PMMA-like is a high-performance photopolymer engineered to replicate and exceed the properties of polymethyl methacrylate (PMMA), combining high stiffness, optical clarity and improved toughness. The material provides transparent to light orange finishes depending on formulation, printing and post-curing conditions, while maintaining excellent dimensional stability and ultra low water absorption. It is available in HV (higher mechanical performance) and LV (lower viscosity) versions for compatibility with SLA, DLP and LCD printing 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.

• Manufacturing aligned with ISO 13485 quality management systems
• Organo-tin free formulation

Material properties are measured on printed and post-processed specimens and may vary depending on the selected material version, printer type, printing parameters, build orientation, post-curing conditions and test specimen preparation. Reported values are indicative and provided for reference only.
