LASER OPERATING MACHINE FOR ADDITIVE MANUFACTURING BY LASER THERMAL TREATMENT, IN PARTICULAR BY FUSION, AND CORRESPONDING METHOD
First Claim
1. A laser operating machine for additive manufacture of objects, via a process of laser thermal treatment of metal powders, in particular via fusion, comprising a movement structure, which is mobile in a working space that comprises a working surface, said machine operating according to a first cartesian system of axes of movement and being configured for supporting a moving element that comprises one or more nozzles for emitting jets of powder to be thermally treated, a working substrate, and an optical laser assembly for conveying a laser beam to form a laser spot focused on said working substrate in order to carry out thermal treatment on said powders,said machine being characterized in that said moving element comprises:
- an upper portion fixedly associated to said movement structure, said optical laser assembly being set in said upper portion;
a lower portion, set in which is a tool-carrier frame arranged on which are said one or more nozzles for emitting jets of powder, said lower portion being configured for rotating said frame about a frame axis parallel to a vertical axis of said first system of cartesian,said optical laser assembly being set in the moving element so as to send the laser beam onto the working surface passing within a perimeter defined by said plurality of nozzles for emitting jets of powder.

Abstract
A laser operating machine for additive manufacture of objects, via a process of laser thermal treatment of metal powders, in particular via fusion, comprising a movement structure, which is mobile in a working space that comprises a working surface, said machine operating according to a first cartesian system of axes of movement and being configured for supporting a moving element comprising one or more nozzles for emitting jets of powder to be treated thermally onto a working substrate, and an optical laser assembly for conveying a laser beam to form a laser spot focused on said working substrate in order to carry out thermal treatment of said powders. According to the invention, said moving element comprises:
an upper portion fixedly associated to said movement structure, said optical laser assembly being set in said upper portion; and
a lower portion, rotatable about an axis parallel to a vertical axis of said first system of cartesian axes, set in which is a tool-carrier frame, arranged on which are said one or more nozzles for emitting jets of powder,
said optical laser assembly being set in the moving element so as to send the laser beam onto the working surface, passing within a perimeter defined by said plurality of nozzles for emitting jets of powder.
