Abstract

The invention belongs to the technical field of a paraffin-type moulding material used for 3D printing, and more specifically provides a paraffin-type moulding material used for 3D printing, and a preparation method thereof. The paraffin-type moulding material used for 3D printing comprises 5 to 55% of a thermoplastic resin, 2 to 40% of a high hardness polymer, 6 to 25% of a long-chain alkane, 10 to 55% of a long-chain acid, 0 to 55% of paraffin, 2 to 20% of a viscosity conditioning agent, and 0.1 to 5% of an anti-oxidant; wherein the long-chain alkane contains 28 or more carbon atoms; the long-chain acid contains 20 or more carbon atoms. The printing precision and printing effect of the paraffin-type moulding material are similar to that of routine materials; needle penetration ranges from 0.9 to 1.3 1 / 10mm; melting point ranges from 70 to 75 DEG C; softening point ranges from 55 to 70 DEG C; viscosity ranges from 25 to 35mpa.s; and the cost is reduced to be about 50% of that of routine materials.

Description

technical field [0001] The invention belongs to the technical field of paraffin wax molding materials for 3D printing, and in particular relates to a paraffin wax molding material for 3D printing and a preparation method thereof. Background technique [0002] In recent years, 3D printers that add ink or molding materials and support materials by stacking them by heating the nozzles of the printer have been commercially available. For example, the 3510 series printers developed by the American 3D system company have been widely used in the jewelry market, and the 3D printing wax spray machines produced by the American Silidscape company have also been used in universities, cultural relics repair, aerospace and other fields. Compared with traditional manual wax carving and wax carving machines, this technology has the advantages of high automation, high efficiency, rich patterns and shapes, low carbon and environmental protection. [0003] The supporting materials used by the...
