Abstract

The invention discloses a 3D printing device and method. The device comprises a printing chamber, a feeding device, a moving support, a printing spray head, a heating body, a pneumatic controller, a printing platform, a mechanical arm and a repairing tool bit. 3D printing is conducted in a melt extrusion condensing mode, the temperature difference of a material sprayed by the printing spray head and a workpiece is strictly controlled, the consistence and quality of the printed and condensed material are guaranteed, the requirement for the material is low, and most of the material can achieve 3D printing. In addition, the printing chamber is provided with the mechanical arm and the repairing tool bit which are used for printing and repairing on the workpiece at the same time, and the 3D printing technology is finally achieved. The 3D printing device and method have the advantages that precision is high, and the range of materials which can be machined is large.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and more specifically relates to a 3D printing device and method. Background technique [0002] 3D printing is currently a popular additive processing technology. At present, the mainstream 3D printing process types on the market include selective laser sintering (SLS), stereolithography (SLA), filament melt extrusion molding (FDM), liquid jet printing molding (3DP), and layered entity manufacturing (LOM). And the corresponding subdivision and derivative technologies of the above types. However, due to the bottleneck of temperature and environment control in the 3D printing process, the existing 3D printing devices have high requirements for printing materials, and the printing materials are relatively simple. There is no universal 3D printing device that can meet the 3D printing of most materials. Moreover, the environmental control of 3D printing is not strict and precise enoug...
