3D printing environment-friendly material and preparation method thereof

Abstract

The invention provides a 3D printing environment-friendly material and a preparation method thereof. The 3D printing environment-friendly material is characterized by comprising the following components in parts by mass: 50-100 parts of PLA (polylactic acid), 8-15 parts of UHMWPE (ultra high molecular weight polyethylene), 10-12 parts of wood flour, 2-5 parts of a compatilizer, 2-4 parts of a coupling agent, 2-4 parts of a lubricant, 2-3 parts of glass beads and 1-2 parts of white masterbatch. The 3D printing environment-friendly material is low-carbon and environment-friendly, can be completely circulated, recycled and reused, has the natural friendliness of wood, has natural wooden fragrance when being used, is good in size stability, is free of hole blocking or warping and is low in processing condition requirement; in addition, a product made of the material is relatively good in physical mechanical property, acid-base resistance, worm damage prevention and weather resistance such as good ultraviolet ray resistance.

Description

technical field [0001] The invention relates to a 3D printing consumable, in particular prepared from an environment-friendly material for 3D printing. Background technique [0002] 3D printing technology has been in existence for more than 20 years. This technology is based on the principle of discrete accumulation and is an advanced additive manufacturing technology. At present, the existing 3D printing consumables are mainly single PLA, ABS, PVA and other materials, but the above materials have their own limitations. The cost of PLA materials is high, and the materials are easy to deform when the temperature is above 55°C, and it is easy to block the nozzle of the equipment. ;ABS material is sensitive to temperature and shear rate, heavy odor, easy to deform and poor weather resistance during processing; while PVA water-soluble material is mainly used for printing support materials, the amount of use is small, and PVA will produce toxic gas when it decomposes . In short...

Problems solved by technology

At present, the existing 3D printing consumables are mainly single PLA, ABS, PVA and other materials, but the above materials have their own limitations. The cost of PLA materials is high, and the materials are easy to deform when the temperature is above 55°C, and it is easy to block the nozzle of the equipment. ;ABS material is sensitive to temperature and shear rate, heavy odor, easy to deform and poor weather resistance during processing; while PVA water-soluble material is mainly used for printing support materials, the amount of use is small, and PVA will produce toxic gas when it decomposes

In short, the 3D printing consumables widely used in the market currently have disadvantages such as high price, high energy consumption, complex and demanding processing conditions, difficult molding, and easy material breakage.
