3Dresyn Bio Corn Corn-Based Resin (88% Bio)

3Dresyn Bio Corn is a bio-based photopolymer formulation developed for environmentally conscious SLA, DLP and LCD 3D printing workflows. The material incorporates approximately 88% total bio-based content derived from renewable sources, including corn-based and other plant-derived constituents functionalized for photopolymerization.

This material is designed to support sustainable additive manufacturing practices while maintaining high resolution and reliable mechanical performance. Under appropriate conditions, the material can undergo partial biological degradation into simpler substances through enzymatic activity.

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within professional, educational and laboratory environments for prototyping, model fabrication and applications where reduced environmental impact is desired.
