Abstract

The invention provides a plant-based biodegradable 3D printing material. The 3D printing material is characterized by comprising the following raw materials in parts by weight: 20 to 45 parts of hot chromium polylactic acid ester containing straw fiber, 10 to 40 parts of polylactic acid ester containing bamboo fiber, 20 to 50 parts of biological rubber, 10 to 25 parts of nylon 11, 2 to 4 parts of hydroxy acrylic resin, 5 to 15 parts of ultra-fine fillers, 1.2 to 3.6 parts of a coupling agent, 1 to 5 parts of photosensitive resin, and 2 to 6 parts of an antioxidant. By performing the simulation of the biological decomposition process in natural environment containing water and microorganism on the 3D printing material according to a GB / T19276.1-2003 standard, the highest biological decomposition rate measured can reach 98 percent, the highest photodegradation rate can reach 92 percent, the highest tensile strength measured can reach 15 MPa, and the highest bending strength can reach 12 MPa.

Description

technical field [0001] The invention belongs to the technical field of 3D printing consumables, and in particular relates to a plant-based degradable 3D printing material. Background technique [0002] 3D printing is a rapid prototyping technology, known as the core technology of the "third industrial revolution". The complex forging process can get the final product, which can realize structural optimization, material saving and energy saving in production. [0003] Materials are the material basis of 3D printing, and they are also the bottleneck restricting the development of 3D printing. At present, the materials used in 3D printing are all from industrial synthetic materials. After the printed products are discarded, the industrial chemically synthesized materials are difficult to photodegrade or biodegrade. The environment has caused a lot of pressure, making the development of 3D printing technology encounter bottlenecks. Contents of the invention [0004] In order...
