Abstract

The invention discloses an ultra violet radiation cross-linking polymeric material for 3D printing and a preparation method and a product thereof. Main components of the material contain, by weight, 100 parts of unsaturated resin and 0.5-5 parts of an UV cross-linking agent. In addition, the material also contains, by weight, 0.1-0.5 part of an antioxidant, 1-20 parts of a powder, 0-10 parts of a pigment and 0-5 parts of other auxiliary agents, which help enhance a printing effect of the material. With the addition of the UV cross-linking agent and by the utilization of ultraviolet irradiation, unsaturated resin is subjected to crosslinking after 3D printing extrusion so as to form a three-dimensional net structure. Heat resistance, resistance to chemical corrosion and mechanical strength of a moulding material are all raised to a large extent. Thus, unsaturated resin has a wider application prospect in 3D printing materials.

Description

technical field [0001] The invention relates to a material for 3D printing, a preparation method and a product thereof, in particular to an ultraviolet radiation crosslinked polymer material for 3D printing, a preparation method and a product thereof. Background technique [0002] 3D printing is a new rapid prototyping technology, based on the computer three-dimensional design model, using laser sintering, heating and melting, etc., materials such as metals, ceramic powders or polymers are controlled by computer digital software programs to accumulate and bond them layer by layer. Shaped to create a physical product. In simple terms, 3D printing can be regarded as the superposition of 2D printing technology in space. Using materials such as solid powder or polymer melt as printing "ink", through computer modeling and design, the precision and size of the product can be precisely controlled. Compared with the traditional molding technology, this printing technology does not...
