3Dresyn CD Bio D Clear Bio-Based Clear Prototyping Resin

3Dresyn CD Bio D Clear is a bio-based Conceptual Design photopolymer resin developed for fast proof-of-concept printing and early-stage model fabrication. The formulation is designed to provide rapid curing, good print definition and cost-effective workflow simplicity for conceptual validation applications.

This plant-based resin incorporates renewable-source content and is intended for users requiring a low-cost material for rapid design iteration before transition to more specialized engineering or application-specific photopolymers. The material is supplied in a natural bio-red color that becomes clear after UV exposure, providing a visual indicator of curing progress during printing and post-curing.

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within professional and laboratory environments for proof-of-concept printing, concept validation and general model fabrication workflows.

Material properties are measured under controlled laboratory conditions and may vary depending on printer type, wavelength, layer thickness, build orientation, washing procedure, post-curing conditions and specimen preparation. Performance must be validated by the user under the intended workflow conditions.

This material is supplied as a professional manufacturing material for proof-of-concept and model fabrication workflows. It is not marketed as a finished medical device. The regulatory classification and compliance of any final part manufactured using this material remain the responsibility of the user or legal manufacturer according to the intended application and applicable regulations.
