Silicon carbide particles for photocuring 3D printing as well as preparation method and application of silicon carbide particles
The invention belongs to the technical field of 3D printing, and particularly relates to silicon carbide particles for photocuring 3D printing and a preparation method and application of the silicon carbide particles. In order to obtain spheroidic silicon carbide primary powder and improve the stacking density of the spheroidic silicon carbide primary powder, the invention provides the preparation method of the silicon carbide particles for photocuring 3D printing, and the preparation method comprises the following steps: mixing silicon carbide powder and a corrosive liquid, firstly heating and reacting for 1-5 minutes at 50-70 DEG C, and then centrifuging, washing and drying to obtain the silicon carbide particles for photocuring 3D printing. According to the method disclosed by the invention, the silicon carbide raw powder is infiltrated in the corrosive liquid, so that sharp corners of the powder are eliminated, the shape of silicon carbide particles gradually becomes spheroidized, and the sphericity degree of the prepared silicon carbide can reach 0.8 or above.
本发明属于3D打印技术领域，具体涉及一种光固化3D打印用碳化硅颗粒及其制备方法和应用。为了获得类球形的碳化硅一次粉末提高其堆积密度，本发明提供了一种光固化3D打印用碳化硅颗粒的制备方法，包括：将碳化硅粉末和腐蚀液混合，先在50～70℃下加热反应1～5分钟min，再经离心、洗涤和干燥，得到所述光固化3D打印用碳化硅颗粒。本发明方法通过将碳化硅原粉浸润在腐蚀液中，消除了粉体的尖角，使碳化硅颗粒形状逐渐变得球形化，制备的碳化硅球形度可达0.8以上。
