Abstract

The invention discloses a high-toughness 3D printing paraffin forming material. The high-toughness 3D printing paraffin forming material is prepared from components of raw materials in percentage by mass as follows: 30%-50% of paraffin, 2%-5% of bee wax, 5%-10% of epoxy resin, 2%-3% of a curing agent, 2%-20% of a viscosity modifier, 20%-30% of a toughening polymer, 6%-25% of a high-hardness polymer, 2%-4% of a filling material, 0.1%-0.3% of dyes and 2%-4% of a phase transferring agent. The bee wax is added to physically modify a paraffin support material, and the impact toughness of the paraffin support material is effectively improved; meanwhile, epoxy resin and the corresponding curing agent are added, and the adding quantity of the epoxy resin and the adding quantity of the corresponding curing agent are adjusted, so that the bonding strength of the paraffin support material and a 3D printing product interface is moderate while the hardness and the strength of the paraffin support material are improved and the shrinkage is reduced, and the paraffin support material is easy to peel off, doesn't deform and doesn't affect the support function on the 3D printing product in the printing process when removed in the later period. The toughening polymer and the high-hardness polymer are added to the paraffin support material, the needle penetration of the material can be effectively reduced, the toughness of the material is improved, and the high-toughness 3D printing paraffin forming material has excellent overall properties.

Description

technical field [0001] The invention relates to a paraffin support material, in particular to a high-toughness 3D printing paraffin molding material and a preparation method thereof. Background technique [0002] Fused Deposition Modeling (FDM—Fused Deposition Modeling) method is one of the 3D printing rapid prototyping technologies. This method uses filamentous materials (paraffin, metal, plastic, low melting point alloy wire) The material is heated to slightly higher than the melting temperature (about 1°C higher than the melting point), under the control of the computer, the nozzle moves in the x-y plane, and the molten material is coated on the workbench, and a layer of cross-section of the workpiece is formed after cooling. After the layer is formed, the nozzle moves up to the height of the layer to coat the next layer, so that the three-dimensional workpiece is formed layer by layer. It can directly accept product design (CAD) data without preparing any molds, cutting...
