3Dresyn HIPS-like, High Impact Polystyrene like

Rigid biocompatible 3D printing resin with HIPS-like mechanical behaviour, combining stiffness, impact resistance and good processability

Product description

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.
