3Dresyn PC-like Polycarbonate Impact-Resistant Engineering Resin

3Dresyn® PC-like is a high-performance photopolymer engineered to replicate the mechanical behaviour of polycarbonate, offering high impact resistance, toughness and good stiffness. The material provides excellent optical clarity with minimal yellowing and incorporates bio-based content from renewable sources. Compared to conventional polycarbonate, it presents a lower glass transition temperature while maintaining strong mechanical performance. 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.

• Follow 3Dresyns IFU for exposure, washing and post-curing to achieve target properties

• Biocompatible formulation platform
• Biocompatibility must be evaluated on the final printed and post-processed device according to ISO 10993
• 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.

• Polycarbonate-like high impact resistance and toughness
• Good stiffness with controlled flexibility
• Bio-based content from renewable sources
• Ultra low water absorption (ULWA) and hydrophobic behaviour
• Very low shrinkage and good dimensional stability
• Available in LV and HV versions for broader processing flexibility
• Open-system compatibility (385–405 nm) across SLA/DLP/LCD workflows

For polycarbonate-like 3D printing applications, compare other rigid engineering resin routes when the required balance shifts between impact resistance, optical clarity and low-friction behaviour.
