Abstract

The invention provides a low-melting-point resin material for a three-dimensional printer. The material comprises the following components in percentage by weight: 30-60% of styrene-acrylic resin, 10-50% of first polyester resin, 0-10% of second polyester resin, 1-15% of additives, 0.5-6% of wax, and 0.1-2% of fumed silica, wherein the glass transition temperature Tg of the styrene-acrylic resin is 55-65 DEG C and the softening point temperature T1 / 2 is 120-130 DEG C; the glass transition temperature Tg of the first polyester resin is 43-48 DEG C and the softening point temperature T1 / 2 is 80-85 DEG C; the glass transition temperature Tg of the second polyester resin is 45-65 DEG C and the softening point temperature T1 / 2 is 80-110 DEG C. By adopting the scheme, the glass transition temperature Tg of the low-melting-point resin material for the three-dimensional printer is 48-65 DEG C and the softening point temperature T1 / 2 is 85-110 DEG C. Therefore, the melting temperature of an FDM three-dimensional printer material is remarkably reduced, and the scald risk of an operator is correspondingly reduced while the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the field of consumables for three-dimensional printers, and in particular relates to a low-melting resin material and a manufacturing method for a three-dimensional printer of fusion deposition molding (FDM). Background technique [0002] Rapid prototyping technology can be used in the forming process of three-dimensional (3D) printing to realize the manufacture of three-dimensional objects through the conversion process of computer data. Generally, 3D printing rapid prototyping technologies mainly include three types: Stereolithography, Laminated Object Manufacturing and Selective Deposition Modeling (SDM). Fused deposition modeling (FDM) is a technical process belonging to selective deposition modeling (SDM). At this stage, FDM 3D printers usually use thermoplastic polymer materials to be extruded from the nozzle in a molten state, solidified to form a thin layer of contour shape, and then stacked layer by layer to form a f...
