Product
FP3D Dark Veined; Model/Catalog Number: 4220442 Product Description: The FP3D is designed for additive manufacturing on Carbon 3D printers (wavelength = 385 nm). FP3D is intended to be used within a computer-aided design and manufacturing (CAD/CAM) digital dentistry system that includes a 3D scanner, design software, 3D printer, post-cure unit (wavelength = 385-405 nm), and post-cure oven for the fabrication of flexible partial dentures for partially edentulous patients. The device is manufactured using dual-cure technology. The resin consists of two parts (Part A and Part B) that are mixed just before printing. Part A is a UV-curable resin, and Part B is a cross-linking diamine agent. When mixed, the resin undergoes free radical polymerization initiated by a photo-initiator in the presence of a UV light source during the 3D printing process. After printing, the device is then thermally cured in an oven to complete polymerization.
