Composite particle material for laser sintering, preparation method of composite particle material and corresponding three-dimensional printing method
The invention discloses a composite particle material for laser sintering, a preparation method of the composite particle material and a corresponding three-dimensional printing method. The provided composite particle material for laser sintering is formed by coating inorganic powder with a binder, the composite particle material for laser sintering is formed by mixing the inorganic powder and the binder, and the binder can be directly coated on the outer surface of the inorganic powder. And moreover, the inorganic powder coated in the material can be powder with smaller particle size and larger particle size range, so that the cost can be greatly reduced, the problem of oxidation of the inorganic powder does not need to be considered due to the fact that the adhesive is coated on the outer layer of the inorganic powder, and the preparation process only needs to be carried out in a general atmospheric environment, so that the cost is greatly reduced. And the used powder material has recoverability.
本发明公开激光烧结用复合颗粒材、其制备方法及相应的三维打印方法。提供的激光烧结用复合颗粒材，是由粘合剂包覆无机粉体所构成，所述激光烧结用复合颗粒材是利用无机粉体与粘合剂混炼而成，使粘合剂能够直接包覆于无机粉体的外表面。又，包覆其中的无机粉体可使用粒径更小且粒径范围更大的粉体，因此成本可大幅下降，加上有粘合剂包覆在无机粉体的外层，所以不需要考虑无机粉体氧化的问题，在制造过程中只需在一般大气环境下进行即可，且使用过后的粉末材料具有可回收性。
