Embodiment Construction

[0018] The present invention will be further described in detail below with reference to the drawings and specific embodiments, but the present invention is not limited to these embodiments.

[0019] The present invention provides a metal additive manufacturing method, which includes constructing a part structure and a support structure layer by layer; when constructing the support structure, the support structure is not formed by the traditional high-energy beam molten metal powder method, but by adhesion The support structure is constructed by bonding the metal powder material with the cement; after the parts are formed, the binder is melted or dissolved by high temperature heating or organic solvent dissolution to remove the support structure.

[0020] In order to realize this method, the present invention provides a metal additive manufacturing device, which adds a glue spraying device 4 in the existing forming chamber. Such as figure 1 Shown is a structure of the device. The d...

Abstract

The invention discloses a metal additive manufacturing method, which includes building a part structure and a support structure layer by layer. When constructing the support structure, the support structure is constructed by using an adhesive to bond metal powder materials; after the part is formed, The adhesive is melted or dissolved by heating at high temperature or dissolved in an organic solvent to remove the supporting structure. The invention also discloses a metal additive manufacturing device used in the method, including a high-energy beam source, an optical unit, a forming chamber, a forming cylinder located in the forming chamber, and a powder spreading device. The forming chamber is also equipped with a glue spraying device, and the glue spraying device Used to provide the adhesive required to build the support structure in the above method. With the support structure constructed by the method and device of the present invention, after the part is formed, it only needs to be heated at high temperature or dissolved in an organic solvent to melt or dissolve the binder, and then the support can be removed without subsequent processing, saving Reduce the cost of post-processing and improve the forming efficiency.

Description

Technical field [0001] The invention belongs to the technical field of metal additive manufacturing, in particular to a metal additive manufacturing method, and also to a metal additive manufacturing device used in the method. Background technique [0002] Additive manufacturing technology, born in the late 1980s, is a rapid prototyping process based on the principle of material accumulation. It is a kind of digital model file based on the use of powdered metal or plastic and other non-metal bonding materials through layer-by-layer accumulation The technology of constructing objects in a different way is not limited by the complexity of parts, and is fully digitally controlled. [0003] As an important part of additive manufacturing technology, metal additive manufacturing mainly uses metal powder, particles or metal wires as raw materials, pre-layered through CAD models, and uses high-power laser beams to melt and build three-dimensional objects. This technology has changed the p...
