3Dresyn BioDeg Corn E Elastic Biodegradable Compostable Corn Resin (85% Bio)

3Dresyn BioDeg Corn E is a bio-based, biodegradable and compostable elastic photopolymer formulation developed for environmentally conscious SLA, DLP and LCD 3D printing workflows. The material incorporates approximately 85% 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 by enabling the fabrication of highly flexible parts with reduced environmental persistence. Under appropriate conditions and processing, the material can undergo biological degradation into simpler substances.

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within professional and laboratory environments for flexible components, prototyping and applications where environmental impact and end-of-life 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, post-processing and degradation conditions. Biodegradation performance depends on environmental conditions and validated processing protocols.

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