Problems solved by technology

[0007] However, since the printing platform moves up and down in the resin tank, on the one hand, due to the contact between the liquid photosensitive resin and the printing platform, the upward force of the printing platform is very large, which may easily cause damage to the bottom material of the liquid resin tank of the printing device
On the other hand, there will be errors due to the movement of the platform, resulting in certain errors in the position of the printed object and the printing accuracy.
At the same time, because the general imaging light is used to irradiate and cure liquid light-curable materials such as resins, its energy is small, so it cannot be used to print and shape metal materials, and there are limitations in use.
And the photo-curing imaging method usually causes a lot of waste of molding materials due to the lack of recycling structure of the molding materials

Abstract

The invention provides a metal three-dimensional printing device and a printing method thereof. Metal powder is used as a binder through a liquid state photocuring material for position three-dimensional curing, then metal three-dimensional primary molding can be achieved, or a molding material containing a metal material is subjected to printing imaging through fused deposition molding, meanwhile, a cutting device is used for planing, cutting or shape polishing during layer-by-layer molding, the photocuring material can be removed subsequently through high-temperature curing sintering, and fusion and connection between metal powder is achieved, and finally three-dimensional printing of a metal model is completed. Due to the fact that DLP photocuring or FDM fused deposition is used for primary molding, the printing molding efficiency and precision are high; and according to the scheme, the metal three-dimensional printing device is low in printing cost, simple in structure and easy to maintain.

Description

technical field [0001] The present invention relates to the field of metal three-dimensional printing, in particular to a light-cured metal three-dimensional printing device, a metal three-dimensional printing device for fused deposition molding, and respective printing methods. Background technique [0002] A 3D printer, also known as a three-dimensional printing device, is a machine that uses rapid prototyping technology. Based on digital model files, it uses molding materials to construct three-dimensional entities by layer-by-layer printing. Before printing, it is necessary to use computer modeling software to model, and then "partition" the built three-dimensional model into layer-by-layer sections, that is, slices, so as to guide the 3D printing device to print layer by layer. 3D printing devices have been widely used in product manufacturing. Specifically, according to the molding method FDM, DLP, SLA, SLS, SLM, 3DP and other 3D molding methods. [0003] Fused depos...
