Production technology of ABS/carbon fiber composite material for FDM printing

Abstract

The invention discloses a preparation technology of an ABS / carbon fiber composite material for FDM printing, and relates to the technical field of 3D printing technology treatment. The preparation technology of the ABS / carbon fiber composite material for FDM printing comprises the following steps: a, raw material preparation; b, drying and mixing; c, proportioning and mixing; and d, material preparation. A carbon fiber is a common material for enhancing the performances of a composite material, so the 3D printing composite material obtained by improving the materials of an ABS material with the carbon fiber has better strength and specific rigidity than the pure ABS material, the ABS / carbon fiber composite material has light weight, good fatigue resistance and good fracture resistance, andthe ABS / carbon fiber composite material is applied to a single-screw FDM wire extruder to extrude and print a wire in order to improve the bending strength, the compressive strength and the hardnessof the wire, enhance the mechanical properties, reduce the surface roughness of the wire and enhance the material properties.

Description

Technical field [0001] The invention relates to the technical field of 3D printing process processing, in particular to a production process of an ABS / carbon fiber composite material for FDM printing. Background technique [0002] As a rapid prototyping technology, 3D printing technology is also called additive manufacturing technology or multilayer manufacturing. It is a definition relative to subtractive manufacturing. It is based on a digital model file and can almost directly manufacture anything The principle of the three-dimensional entity technology of the shape is a molding technology in which materials are added in layers through physical, chemical and other means. [0003] 3D printing also has new information, intelligent manufacturing, and material technology. It will change the traditional manufacturing and production methods. Its market scale will be further expanded with the development and maturity of technology. At present, 3D printing ABS materials for FDM are curr...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a production process of ABS / carbon fiber composite material for FDM printing, which solves the above-mentioned background technology. At present, the technical means for preparing 3D printing ABS materials for FDM on the market are mainly through fillers, polymerization The way of blending materials is used to change, improve the printing performance of its part or give it new properties. When the composite material prepared by blending filler and ABS is difficult to form, the toughness is relatively poor, and the surface after forming is relatively rough. The problem of high printing temperature and difficult preparation
