Problems solved by technology

However, during the printing and molding process of 3D printing wax models, a large number of support structures will be produced, and the removal of support structures will directly affect the appearance and post-processing of the wax models
The world patent WO2010132392A2 mixes alcohol wax and rosin resin to obtain 3D printing support wax for MJP 3D printers, but the support wax is insoluble in water and only soluble in alcohol solvents. Wax will also have problems such as slight dissolution
In order to improve the safety of removing the solvent of the support wax and prevent the micro-dissolution of the wax pattern, Chinese patent CN103476570B adopts ethoxylated fatty alcohol and a water-soluble tackifier to prepare a water-dispersible support wax, but the water-dispersibility is different from the water-solubility, Not only is it difficult to remove the support wax, which makes the post-processing more complicated, but also the residual support wax will affect the printing accuracy and casting accuracy of the wax model

Abstract

The invention discloses a water-soluble 3D-printing supporting wax. The water-soluble 3D-printing supporting wax comprises the following components in parts by weight: 20-90 parts of polyethylene glycol wax, 5-50 parts of a water-soluble tackifier, 0.1-1 part of a nucleating agent, and 0.1-0.5 part of an antioxidant. The invention further provides a preparation method of the supporting wax. The supporting wax has the characteristics of being fast in dissolving speed in water, high in printing accuracy, simple in removing processes, safe, environmentally friendly, and suitable for massive application; meanwhile, a printing wax die cannot be damaged, so that the wax die printing accuracy and the casting accuracy are improved.

Description

technical field [0001] The invention relates to the field of preparation of 3D printing materials, in particular to a water-soluble 3D printing support wax and a preparation method thereof. Background technique [0002] Compared with traditional technologies, 3D printing wax molds have the advantages of cost saving, high intelligence, high complexity, and no need for molds. Therefore, the lost foam casting process can be widely used in precision casting industries such as jewelry. At present, 3D printing wax is divided into three types: wire, powder and block. 3D printing wax wire is used for FDM (Fused Deposition) 3D printers, 3D printing wax powder is used for SLS (Selective Laser Sintering) 3D printers, 3D printing wax The blocks are used in MJP (multi-jet inkjet) 3D printers, where the printing accuracy of MJP 3D printers can reach 16 μm, the printing speed is fast, and it has the incomparable advantages of FDM and SLS 3D, so it has great application prospects. However,...
