Description

technical field [0001] The invention relates to the technical field of 3D printing materials, in particular to a high-strength and high-toughness 3D printing material for construction. Background technique [0002] 3D printing has created a new principle of additive forming. In the early stage of its development, due to the unqualified material technology, it can only be used for rapid prototyping, making this new technology once famous all over the world as "rapid prototyping" technology. With the development of material technology, 3D printing has entered a new stage of direct manufacturing of high-performance components, thus opening the prelude to the revolutionary development of manufacturing. 3D printing technology has penetrated into most areas of people's lives, and when printing technology is used in the construction field, the strength and toughness of the 3D printing materials used in the printing cannot meet the needs of actual production. Therefore, it is neces...
