Precision casting powder material for 3D printing and preparation method thereof
The invention relates to a precision casting powder material for 3D printing and a preparation method thereof. The casting powder material is composed of the following components in parts by mass: 82-94 parts of a refractory material, 1-5 parts of a fluxing agent, 1-5 parts of a toughening agent, 2-4 parts of a plasticizer and 2-4 parts of a dispersion enhancer. In view of the problems of variousprocesses, complex material use, poor comprehensive performance, low production efficiency, low shell strength, long manufacturing period and the like in the prior art, based on the precision castingpowder material for 3D printing and the preparation method thereof, successful application of the powder material in the precision casting direction of 3D printing is achieved, only one composite material with excellent heat dissipation performance is needed for the material from many previous materials to now, and intelligent casting, short period, high efficiency and large-scale production are achieved. The powder can be used for directly printing a complex precisely-cast shell through a 3D printer.
本发明涉及一种3D打印用精密铸造粉末材料及其制备方法。所述铸造粉末材料按质量份由以下组分组成，包括耐火材料82～94份、助熔剂1～5份、增韧剂1～5份、增塑剂2～4份和分散增强剂2～4份。本发明针对现有技术中工艺繁多、材料使用复杂、综合性能较差、生产效率低、型壳强度较低、制造周期长等问题，提出一种3D打印用精密铸造粉末材料及其制备方法，实现了粉末材料在3D打印精密铸造方向的成功应用，材料由以前材料众多到现在的只需要一种散热性优良的复合型材料，实现铸造智能化、周期短、效率高、规模化生产。所述粉末可以通过3D打印机直接打印出复杂精密铸造的型壳。
