Embodiment Construction

[0018] In the following description, numerous specific details are provided in order to allow the greatest understanding of the exemplary embodiments. Embodiments may be practiced with or without the specific details, or with other methods, components, materials, and the like. In other instances, well-known material structures or operations have not been shown or described in detail to avoid obscuring aspects of the embodiments. Reference in this specification to "an embodiment" indicates a particular feature, structure, or characteristic described in connection with an embodiment that is included in at least one embodiment. Thus, the use of the phrase "in one embodiment" in various places within this specification does not necessarily refer to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more embodiments.

Abstract

A laser-operated machine for the additive manufacturing of objects by laser sintering, comprising: a transport structure (11), which is movable in a workspace (100), according to a first movement axis (X, Y, Z) system operating, and configured to support one or more nozzles (34) for emitting jets of sintering powder to be sintered on a working substrate (100, 110); and for delivering a laser beam (L) to focus on said working substrate ( 100, 110) on the laser spot (S) to sinter the optical laser component (20) of said powder. According to the invention, said optical laser assembly (20) is integrally associated with said delivery structure (11), and the movable element (12) is also integrally associated with said delivery structure (11), according to the second movement axis (u, v) System operation, said movable element (12) comprising a tool-carrying frame (30) on which one or more nozzles (34) for firing a jet of sintering powder are arranged, the nozzles (34) being connected to The second axis of movement (u,v) is systematically associated and movable relative to the optical laser assembly (20).

Description

technical field [0001] The present description relates to a laser-operated machine for the additive manufacturing of objects by laser sintering comprising one or more nozzles having a first movement axis system and configured to support one or more nozzles for emitting a jet of sintering powder onto a working substrate A delivery mechanism, and a laser device for delivering a laser beam (L) focused in a laser spot (S) on the working substrate to sinter the powder. [0002] Various embodiments can be applied to sinter larger volume objects starting from thermoplastic or metallic sintering powders (stainless steel, aluminum, titanium, cobalt chrome, nickel superalloys, noble alloys) and any combination thereof. Background technique [0003] The manufacturing additive process for laser sintering consists of depositing successive layers of sintering powder to form complex geometries. Several fields of manufacturing production, such as the automotive and aerospace fields, consid...
