Laser operating machine for additive manufacturing by laser sintering and corresponding method

摘要

Laser operating machine for additive manufacturing of objects by laser sintering, comprising a transport structure (11), which is movable in a work space (100), operating according to a first system of movement axes (X, Y, Z) and configured to support one or more nozzles (34) for lid emitting sintering powder jets to be sintered on a work substrate (100, 110) and an optical laser assembly (20) for conveying a laser beam (L) in a laser spot (S) focused on said work substrate (100, 110) to sinter said powders, According to the invention, said optical laser assembly (20) is integrally associated with said transport structure (11) and a movable element (12) is also integrally associated with said transport structure (11) operating according to a second system of movement axes (u, v), said movable element (12) comprising a tool-carrier frame (30), on which one or more nozzles (34) for emitting sintering powder jets are arranged, associated with said second system of movement axes (u,v) and movable with respect to said optical laser assembly (20).
