3Dresyn Bio Soya1 Soy-Based Resin (82% Bio)

3Dresyn Bio Soya1 is a bio-based photopolymer formulation incorporating renewable plant-derived components, designed for environmentally conscious SLA, DLP and LCD 3D printing workflows. The material contains approximately 82% total bio-based content derived from soya and other vegetable-based constituents functionalised for photopolymerization.

This material is developed to support sustainable additive manufacturing by enabling the production of high-resolution parts with reduced environmental impact compared to conventional photopolymers.

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within professional, educational and laboratory environments for prototyping, model fabrication and general-purpose applications where sustainability is a relevant factor.
