Problems solved by technology

At present, the PLA modified materials sold in the market are basically linear materials for desktop-level 3D printers, and there are very few granular large-scale industrial-grade PLA modified materials; moreover, the products printed by these modified materials are currently There are many disadvantages, such as warping, cracking, poor adhesion, late deformation, etc.
[0007] At present, printing materials have seriously hindered the further development of the 3D printing industry; therefore, it is necessary to develop a low-cost, green and low-carbon environmental protection, good dimensional stability, high strength, non-blocking holes, continuous filaments, and no warping during processing. FDM 3D printed PLA modified material with advantages such as bending deformation

Abstract

The invention discloses a granular PLA modified material for FDM printing and a preparation method of the granular PLA modified material for the FDM printing, and in particular relates to a novel environmental protection PLA modified material of the FDM printing for large industry and the preparation method of the novel environmental protection PLA modified material for the FDM printing. The granular PLA modified material for the FDM printing comprises the following components in parts by weight: 100 parts of polylactic resin, 10 to 30 parts of inorganic fillers, 5 to 30 parts of polymer elastomers and 1 to 10 parts of other additives. The PLA modified material is manufactured by granulating the components through a mixing extrusion process. The product disclosed by the invention is easy to degrade, environment-friendly and non-toxic, smooth in printing, free of smells and pollution and high in safety coefficients, the printed product has the good characteristics of smooth surface, beautiful appearance, symmetry, stable dimension, difficult shrinkage and the like and is very suitable for use in an FDM 3D printer. Furthermore, waste materials in the production process can be fully recovered and recycled. According to the invention, the polymer elastomers are added, so that the durability of the product printed by using the PLA material is further better than that of the conventional PLA material, and the product further can withstand more pressure and wear.

Description

technical field [0001] The invention relates to the technical field of polymer materials and 3D printing technology, in particular to a novel environmentally friendly PLA modified material and a preparation method for large-scale industrial FDM printing. Background technique [0002] FDM technology is the most widely used and most vital 3D printing technology. It is a fast, safe and cheap rapid prototyping process. It is easy to operate, low in equipment cost, and simple in process. Printing materials are the main technical bottleneck for the further development of 3D printing. The consumables suitable for FDM 3D printers must not only meet the requirements of high mechanical strength, low shrinkage, and suitable melting temperature, but also meet the requirements of safety, non-toxic, non-irritating, etc. Environmental requirements. [0003] At present, the consumables suitable for FDM printing technology mainly include acrylonitrile-butadiene-styrene copolymer (ABS), poly...
