Problems solved by technology

[0004] In the process of additive manufacturing, STL format and two-dimensional layering technology are mostly used in the data discretization process, which will inevitably cause size errors and step effects
The smaller the thickness of the layer, the higher the accuracy, but also the longer the time required, which increases the cost and reduces the forming efficiency

Abstract

The invention discloses a composite forming device of molten coating added and decreased materials. The composite forming device comprises a coating added material forming part and a decreased material machining part arranged on the same one motion platform; the coating added material forming part includes an atmosphere protecting device; the atmosphere protecting device is connected with the top of a smelting device; a coating head and a laser are arranged at the bottom of the smelting device; a coating forming platform is arranged below the laser and the coating head; the decreased material part includes a main shaft; a cutter clamping device is arranged at the bottom of the main shaft; the main shaft drives the cutter clamping device to rotate; and the main shaft is connected with a cooling unit. The added material manufacturing and the decreased material manufacturing are combined; and after the coating added material forming is performed, the decreased material machining is used, the workpiece precision is improved, and the workpiece machining speed is accelerated.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and relates to a forming device for coating adding and subtracting materials, in particular to a composite forming device for melting and coating adding and subtracting materials. Background technique [0002] Additive manufacturing technology, also known as "3D printing", is rapidly changing traditional production and lifestyles. Its core idea is to discretize three-dimensional parts in two dimensions to form layered data. According to the layering of the three-dimensional CAD model of the part Data, the discrete forming materials are gradually combined to form layered cross-sections, and then piled up layer by layer to form solid parts. The parts can be directly manufactured without molds, which can greatly reduce costs and shorten the development cycle. At present, relatively mature metal parts additive manufacturing technologies mainly include laser rapid prototyping, such as selective la...
