Abstract

The invention relates to a thermosetting non-photocureable 3D printing material and a printing method thereof. The 3D printing material is a thermosetting resin, and is composed of a component A and a component B. The component A consists of epoxy resin, a toughening agent, a flame retardant, filler, a defoaming agent and a pigment, and the component B consists of a curing agent, a defoaming agent and other components. The method includes: firstly subjecting the component A to thin layer printing, subjecting the component B to spray deposition to the surface layer of the component A, and performing fast curing; repeating the component A thin layer printing, conducting spray deposition on the component B to the surface layer of the component A until a model is completely printed; and then carrying out medium temperature post-curing so as to obtain a print model with high strength, smooth surface and good toughness.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a thermosetting non-light-curing 3D printing material and a printing method thereof. Background technique [0002] 3D printing is the main form of "Additive Manufacturing". The concept of "additive manufacturing" is different from traditional "removal" manufacturing. Additive manufacturing technology is a technology that uses computer design data to manufacture entities by layer-by-layer accumulation of materials, including stereolithography (SLA), laser selective sintering (SLS), laser selective melting (SLM), and fused deposition modeling. Technology (FDM), laser near-net shape technology (LNSF), layered solid manufacturing technology (LOM) and three-dimensional printing technology (3DP). The printing materials used include ABS resin, polylactic acid (PLA), polyvinyl alcohol (PVA), photosensitive resin, wood-plastic material, polycarbonate (PC), nylon, etc. [0003] Both...
