3Dresyn OD RDB MF Monomer-Free Rigid Denture Base Resin

3Dresyn® OD RDB MF is a rigid monomer-free gingiva-colored dental photopolymer formulation developed for professional laboratory fabrication workflows of denture-base-type dental components requiring high mechanical strength, dimensional stability and reduced residual monomer architecture.

Available in three natural gingiva-inspired shades. Final color outcome may vary depending on printing and post-processing parameters.

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within controlled professional laboratory environments. Final suitability, validation and regulatory compliance of printed parts must be assessed by the user according to the specific device design, workflow validation and applicable regulatory requirements.
