METHODS OF PRODUCING POLYURETHANE THREE-DIMENSIONAL OBJECTS FROM MATERIALS HAVING MULTIPLE MECHANISMS OF HARDENING |
摘要 |
A method of forming a three-dimensional object comprised of polyurethane, polyurea, or copolymer thereof is carried out by: (a) providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween; (b) filling the build region with a polymerizable liquid; (c) irradiating the build region with light through the optically transparent member to form a solid blocked polymer scaffold and advancing the carrier away from the build surface to form a three-dimensional intermediate having the same shape as, or a shape to be imparted to, the three-dimensional object, with the intermediate containing the chain extender; and then (d) heating or microwave irradiating the three-dimensional intermediate sufficiently to form from the three-dimensional intermediate the three-dimensional object comprised of polyurethane, polyurea, or copolymer thereof. |
