3Dresyn HIPS-like High-Impact Polystyrene Rigid Engineering Resin

3Dresyn® HIPS-like is a high-performance engineering photopolymer designed to replicate the mechanical behaviour of high impact polystyrene (HIPS), combining rigidity, toughness and impact resistance.

The formulation provides excellent optical clarity with minimal yellowing and incorporates bio-based content from renewable sources. It is available in HV (higher mechanical performance) and LV (lower viscosity) versions to ensure compatibility across a wide range of SLA, DLP and LCD systems.

Designed for functional engineering and biomedical applications requiring rigidity, impact resistance and reliable processing.

Material properties are measured under controlled laboratory conditions and may vary depending on printer type, exposure conditions, layer thickness, build orientation and post-processing workflow.

This material is supplied as a professional engineering material. Final part performance and suitability must be validated by the user according to the intended application and regulatory requirements.

For HIPS-like engineering applications, compare adjacent resin routes when impact behaviour, toughness or flexibility requirements change.
