Abstract

The invention discloses a wheat straw powder composite wire for fused deposition modeling and a preparation method and a 3D (Three-dimensional) printing method thereof, and belongs to the technical field of a preparation technology and application of composite materials. At present, a 3D printing technology is in rapid development, but materials suitable for 3D printing are in slow development. The wheat straw powder composite wire for the fused deposition modeling is prepared from the following raw materials in parts by weight: 1 to 5 parts of wheat straw powder, 95 to 99 parts of polylactic acid, 0.02 to 0.4 part of a coupler, 0.5 to 1.5 parts of a compatilizer and 0.2 to 1 part of a lubricant. A product printed by the wheat straw powder composite wire for the fused deposition modeling, disclosed by the invention, has a woodiness feeling, the raw materials of the wheat straw powder and the polylactic acid are completely biodegradable, and any pollution to an environment cannot be caused.

Description

technical field [0001] The invention belongs to the field of preparation technology and application technology of composite materials, and in particular relates to a wheat straw powder composite wire for fused deposition molding, a preparation method thereof, and a 3D printing method. Background technique [0002] At present, 3D printing technology is developing rapidly, but the materials suitable for 3D printing are developing slowly. The existing special metal powder and other materials are mainly suitable for industrial-grade 3D printing and are expensive. The 3D printing materials that can be used for household use are limited to gypsum, resin, plastic, etc., which are far from meeting the market demand. Obviously, proposing more new composite materials that can be used for 3D printing has great market prospects and is of great value for solving the material bottleneck of 3D printing. As the country puts forward more and more requirements for green environmental protect...
