Abstract

The invention provides a modified 3D printing material and a preparation method thereof. The modified 3D printing material comprises the following components in parts by weight: 60-100 parts of polyamide, 30-80 parts of epoxy resin, 20-30 parts of rosin resin, 20-60 parts of monocrystal sapphire whiskers, 1-10 parts of a coupling agent, 0.1-5 parts of a flatting agent, 0.1-5 parts of a degassing agent and 1-10 parts of a dispersion lubricant. Compared with the traditional polyamide material, the modified 3D printing material provided by the invention is relatively high in flexural modulus, tensile strength, size stability and heat distortion temperature and can be used at high temperature.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a preparation method of a modified 3D printing material. Background technique [0002] The principle of 3D printing technology is stacked manufacturing, which is a technology that increases materials layer by layer to generate three-dimensional entities, so it is also called additive manufacturing technology. This technology is used in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), Dental and medical industries, education, geographic information systems, civil engineering, automotive, aerospace, firearms, and other fields have applications. Since the birth of 3D printing, it has transformed from industrial and architectural model printing to functional and service products. In the context of future intelligent manufacturing, 3D printing technology will integrate with other advanced technologies such as the Internet, cloud co...
