Abstract

The invention belongs to the technical field of polymeric materials and particularly relates to a nylon wire for 3D printing and a preparation method thereof. The nylon wire for 3D printing is made from 50-90 parts of nylon 12 granules, 10-30 parts of talcum powder masterbatch, 5-25 parts of a maleic anhydride grafted polymer, 2-10 parts of a coupling agent, 0.5-2 parts of an antioxidant, 0.2-1.5parts of a lubricant, and 1-5 parts of color masterbatch. The preparation method herein includes the steps of drying materials, mixing at high speed, blending and extruding for granulating, drying forthe second time, and extruding a wire. The nylon wire for 3D printing provided herein has low cost, good processing convenience, low shrinkage, good stability and high mechanical strength; a printedarticle is free of evident warping and has high precision.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a nylon wire for 3D printing and a preparation method thereof. Background technique [0002] 3D printing (3DP) is a technology based on digital model files, using bondable materials such as powdered metal or plastic, to construct objects by layer-by-layer printing. High efficiency, convenient and easy to operate and so on. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and others. [0003] Fused deposition type (FDM) is one of the most widely used 3D printing processes at present. It has the characteristics of simple system structure, convenient operation, low cost, wide variety of printing materials, and high utilization rate. The forming principle of FDM i...
