ADDITIVE MANUFACTURING APPARATUS COMPRISING GANTRY DEVICE USING REFLECTING ELEMENTS TO DIRECT LASER BEAM TO MOVABLE SCANNER

摘要

We disclose herein an apparatus for an additive manufacturing process, the apparatus comprising:a structure for providing a target area for producing a3D part; a gantry device located on top of the target area of the structure, wherein the gantry device comprises: a first primary reflecting element for receiving a collimated beam from a light source; a first secondary reflecting element for receiving at least a portion of said collimated beam from the first primary reflecting element; a first scanner comprising a focal element for directing the at least a portion of said collimated beam to the target area, wherein the apparatus further comprises a controller configured to move the first scanner of the gantry device over the target area in a first direction along a longitude of the apparatus and in a second direction transverse to the first direction.
