Abstract

The invention discloses a polyvinyl alcohol water-soluble 3D (Three-dimensional) printing support consumable item and a preparation method thereof. The polyvinyl alcohol water-soluble 3D printing support consumable item is prepared from the following components:60 to 90 parts of polyvinyl alcohol, 10 to 40 parts of plasticizer, 0.1 to 1 part of antioxidant, 0.1 to 5 parts of heat stabilizer, 0.5 to 2 parts of fluidity modifier, and 0.1 to 1 part of melt bonding enhancer. The preparation process comprises the steps of (1) adding the polyvinyl alcohol and the plasticizer into a mixer, and aftermixing and stirring, putting into a drying box; (2) adding the mixture, the antioxidant, the heat stabilizer, the fluidity modifier and the melt bonding enhancer into the mixture, and uniformly stirring; (3) after drying the mixture, adding to a pelletizer for extruding and pelletizing, and obtaining polyvinyl alcohol modified particles through co-mixing, pulling, air-cooling and dicing; (4) extruding the particles through the 3D printing consumable item so as to form threads, and rolling. The polyvinyl alcohol water-soluble 3D printing support consumable item and the preparation method thereof provided by the invention effectively solve the problem of poor bonding, the supportability is improved, the water solution speed is improved, and meanwhile, the requirement on water solution temperature is reduced.

Description

technical field [0001] The invention relates to the technical field of 3D printing consumables, in particular to a polyvinyl alcohol water-soluble 3D printing support consumable and a preparation method thereof. Background technique [0002] 3D printing technology, also known as additive manufacturing technology, is a type of rapid prototyping technology. It is based on digital model files and uses bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. technology. At the end of the 20th century, the rapid development of computer technology and material technology promoted the sudden emergence of 3D printing technology in the manufacturing industry. With the rapid development of material science, rapid prototyping technology is constantly developing in all walks of life. At present, 3D printing has been widely used in aerospace, automobile industry, medical supplies, electronic appliances, art design, daily necessities and other...
