Description

technical field [0001] The invention belongs to the field of building materials, in particular to a 3D printing building material. Background technique [0002] In the traditional construction method, the labor intensity and labor consumption are high, the amount of construction waste and dust is large, and the pollution is serious. Problems such as the inability to reserve circuit channels, ventilation channels, and functional openings have brought great inconvenience and trouble to construction operations. With the rapid development of emerging technology 3D printing in the manufacturing industry, it has brought subversion to traditional construction models. change. However, the current 3D printing materials are generally polymer materials or metal materials, polymer materials such as ABS, PLA, PVA, etc., and metal materials such as aluminum materials, titanium alloys, stainless steel, silver-plated materials, etc. The above materials are used for When printing architect...
