3Dresyn Bio D Bio-Based Soy Resin with Photo-Oxidative Catalysts (81% Bio)

3Dresyn Bio D is a bio-based photopolymer formulation designed for environmentally conscious SLA, DLP and LCD 3D printing workflows. The material incorporates 3Dresyn Bio Soya1 as a primary bio-based component, combined with enzymatic and photo-oxidative catalyst systems to promote accelerated degradation pathways under appropriate conditions.

This formulation includes bio-catalysts and pro-degradant additives engineered to support both biological and photo-oxidative degradation mechanisms, enabling reduced environmental persistence 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 applications where environmental degradation and lifecycle considerations are relevant.

Material properties are measured under controlled laboratory conditions and may vary depending on printer type, wavelength, formulation tuning, layer thickness, build orientation and post-processing conditions. Degradation performance depends on environmental exposure conditions and workflow validation.

This material is supplied as a professional manufacturing material for prototyping and model fabrication workflows. It is not marketed as a finished medical device. Environmental behaviour and degradation performance of final parts must be evaluated by the user under intended conditions of use and disposal.
