Multidimensional laser printing device and method capable of manufacturing large-angle cantilever structure workpiece

Abstract

The invention relates to a multidimensional laser printing device and method capable of manufacturing a large-angle cantilever structure workpiece. The multidimensional laser printing device comprises a support frame, an X-axis transmission device, a Y-axis transmission device, a Z-axis transmission device, a laser printing device and a working platform, and is characterized by further comprising a mechanism rotating around an X axis and arranged at the connecting part of the working platform and the Z-axis transmission device, and a mechanism rotating around an Z axis and arranged in the center of the working platform; a forming platform is further arranged between the working platform and a forming bottom plate; the forming bottom plate is fixed on the forming platform through bolts. The multidimensional laser printing method comprises the steps of three-dimensional plotting, image processing, code generation, device adjustment, workpiece printing and device reset. The multidimensional laser printing device and the multidimensional laser printing method have the benefit that a software technology is utilized to distinguish a main body part and a cantilever part of a workpiece, the main body part and the cantilever part are respectively arranged on a horizontal plane to perform two-dimensional scanning and the Z axis is gradually changed, so that the three-dimensional formation is completed, and a large-angle cantilever structure workpiece which is manufactured by direct laser cladding without any support is obtained eventually.

Description

technical field [0001] The invention relates to the field of laser multi-dimensional printing devices, in particular to a laser multi-dimensional printing device and method capable of manufacturing large-angle cantilever structural parts. Background technique [0002] At present, laser multi-dimensional printing printing technology (3D printing technology) is a kind of forming method based on the principle of discrete-stacking for direct personalized manufacturing of workpieces with arbitrary complex shapes, mainly including photocuring, melt extrusion technology, layered entity manufacturing, laser Selective sintering / melting, laser cladding rapid manufacturing, electron beam selective melting forming, 3DP technology, etc. [0003] Since 3D printing technology is manufactured in layers, the support structure needs to be considered in the manufacture of workpieces with large-angle cantilever structures. The support of photocuring molding and melt extrusion manufacturing is ...
