3Dresyn OD FDB Flexible Denture Base Resin

Product description

3Dresyn® OD FDB Flexible is a gingiva-colored flexible dental photopolymer formulation developed for professional laboratory fabrication workflows of flexible denture-base-type dental components requiring controlled elasticity, dimensional stability and mechanical durability.

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

Application framework

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.
