Method for preparing and printing thermoplastic carbon fiber composite building 3D printing material
The invention discloses a method for preparing and printing a thermoplastic carbon fiber composite building 3D printing material, which comprises the following steps: in the process of mixing dry powder of the building 3D printing material, doping 2-5% by volume of thermoplastic chopped carbon fiber, and fully and uniformly stirring; the preparation method comprises the following steps: adding 5%-10% of water according to the mass percentage, carrying out wet material mixing preparation of a 3D printing material, pumping the wet material into a stock bin of building 3D printing equipment, carrying out stirring and extrusion again, and carrying out 3D forming printing by the building 3D printing equipment according to a designed component printing path; after the component is formed and before hardening, a power line is inserted into a design position of the component according to the requirement of a subsequent use scene of the component, and wiring heating is performed during subsequent use. According to the method, the thermoplastic carbon fiber material is adopted as a blend of a printing material and is applied to building 3D printing, by designing a proper printing construction method, high strength and high toughness of a printed component are guaranteed, and the printed component further has certain conductivity.
本发明公开了一种热塑性碳纤维复合型建筑3D打印材料制备与打印的方法，包括步骤：在建筑3D打印材料干粉混合过程中，按体积掺量2％～5％掺入热塑性短切碳纤维，充分搅拌均匀；按质量百分比掺入5％～10％的水，进行3D打印材料的湿料混合制备，并将湿料泵送至建筑3D打印设备的料仓中，进行再次搅拌及挤出，建筑3D打印设备按照设计好的构件打印路径，进行3D成型打印；构件成型后，在硬化前，根据构件后续使用场景需要，将通电线插入构件设计位置，待后续使用时接线加热。本发明方法采用热塑性碳纤维材料作为打印材料的掺合物，在建筑3D打印中得到应用，通过设计合适的打印施工方法，保证打印构件的高强度和高韧性，还具有一定的导电性。
