3Dresyn OD FRV Flexible Removable Veneer Resin (Vita Colors)

Product description

3Dresyn® OD FRV is a flexible colored dental photopolymer developed for professional laboratory fabrication workflows of aesthetic dental components and colored appliance elements.

The material combines controlled flexibility, dimensional stability and optimized optical performance for shade-matching applications.

It is available in multiple tooth-inspired shades and supports both rigid and flexible configurations depending on processing and workflow requirements.

Available shades: A1, A2, A3, A3.5, A4, B1, B2, B3, B4, C1, C2, C3, C4, D2, D3, D4 and BL1. Final shade appearance may vary depending on printing and post-processing conditions.

Application framework

Designed for use in vat photopolymerization (SLA, DLP and LCD) systems within controlled professional laboratory environments.

Final suitability and regulatory compliance of printed parts must be validated by the user according to the specific device design, workflow validation and applicable regulatory requirements.
