3Dresyn OD-Clear F Flexible – Flexible Clear Dental Photopolymer for Professional Laboratory Fabrication Workflows

Product description

3Dresyn® OD-Clear F Flexible is a transparent flexible dental photopolymer formulation developed for professional laboratory fabrication workflows of resilient guard-type dental components and flexible appliance elements requiring elasticity, dimensional stability and optical clarity.

Application framework

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) 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, processing protocol and applicable regulatory requirements.
