Abstract
The invention discloses an additive manufacturing method for powder printing and sintering laser composite processing. For sinterable powder materials, powder printing and follow-up heating are used to rapidly sinter and shape the powder, and a powder sintering that is one circle larger than the model is obtained. Layer, laser scanning is used to precisely modify the powder printing and sintering layer to realize the layer-by-layer printing of the model. The technical effect of the present invention is: the present invention proposes a powder sintering molding method, adopts the strategy of multi-material printing and sintering to complete rough processing, powder printing and sintering realizes both printing efficiency and format, introduces laser processing, and sinters the area of molding Precise processing and removal of residual materials have the characteristics of short processing time and high processing accuracy. In combination, the invention can realize a low-cost, high-efficiency, large-format, and high-precision additive manufacturing process.
Description
An additive manufacturing method for powder printing and sintering laser composite processing technical field The present invention relates to the field of additive manufacturing, namely 3D printing, in particular to a kind of additive manufacturing of powder printing sintering laser composite processing. material manufacturing method. Background technique Additive manufacturing (AM), also known as solid freeform manufacturing or 3D printing, refers to the creation of three-dimensional objects from raw materials (usually A manufacturing process that builds up in a series of two-dimensional layers or cross-sections as powders, liquids, suspensions or molten solids. [0003] The traditional additive manufacturing method for constructing a printed entity based on powder materials is mainly divided into the following methods: SLS (Selective Laser Sintering) method, selective laser melting SLM (Selective Laser Sintering) method Laser Melting) method, binder injection mold...
