MACHINE AND METHOD FOR POWDER-BASED ADDITIVE MANUFACTURING

摘要

Machine for the additive manufacture of a three-dimensional object by sintering or melting powder using a beam of energy acting on a layer of powder in a working zone, the said working zone being defined in the upper part
of a build sleeve fixedly mounted in a chassis, in which sleeve the said object is manufactured, the said object being supported bya build plate which slides inside the said build sleeve when driven in vertical translation bythe head of an actuating cylinder placed along the central axis of the said sleeve. The build plate is positioned inside a transport container which is arranged removably between the said sleeve and the said actuating cylinder,the machine comprises means for moving the transport container (60) vertically into contact with the build sleeve andthe container is open at its top and at its bottom so that, when the actuating cylinder is actuated, the head thereof can transfer the said plate between the said transport container and the said build sleeve which forms a build envelope around the said plate.

1. A machine for the additive manufacture of a three-dimensional object by sintering or melting powder using a beam of energy acting on a layer of powder comprising:
a working zone, wherein the working zone is defined in an upper part of a build sleeve in which the three-dimensional object is manufactured; a chassis, in which the build sleeve is fixedly mounted; a build plate which supports the three-dimensional object, and which slides inside the build sleeve when driven in vertical translation; the a head of an actuating cylinder placed along the central axis of the build sleeve, and which drives the build plate in vertical translation; wherein the build plate is positioned inside a transport container is arranged removably between the build sleeve and the actuating cylinder, means for moving the transport container vertically into contact with the build sleeve and wherein the container is open at its top and at its bottom so that, when the actuating cylinder is actuated, the head thereof can transfer the plate between the transport container and the build sleeve, which forms a build envelope around the build plate.
