Dental 3Dresyn IJ OD Clear TF – Inkjet Photopolymer for Professional Orthodontic Laboratory Workflows

3Dresyn IJ OD Clear TF is a clear tough and foldable photopolymer formulation designed for high-performance inkjet 3D printing applications in professional orthodontic laboratory workflows. The material is engineered to deliver controlled flexibility, mechanical strength and durability, enabling direct fabrication of transparent orthodontic devices with high precision and repeatability.

This formulation provides a balance between rigidity and flexibility, allowing the production of transparent parts with accurate fit, controlled force delivery and reliable dimensional stability. The material is suitable for thin-wall applications while maintaining structural integrity and resistance to deformation.

Designed for use in commercial and professional inkjet 3D printing systems within orthodontic laboratories and dental environments for manufacturing direct printed aligners, flexible copings and indirect bonding trays.
