Problems solved by technology

[0005] However, the gypsum-based 3D printing materials currently on the market not only have a cumbersome preparation process, but also have the disadvantages of low early strength and long hardening time. Therefore, it is necessary to study a 3D printing material with desulfurized gypsum as the main raw material.

Abstract

The invention discloses a three-dimensional printing material taking desulfurized gypsum as a main raw material. The three-dimensional printing material is prepared from the following components by weight percentage: 5-8% of sodium alginate, 0.5-1.2% of urea resin, 0.5-1.2% of an anti-sticking agent, 0.2-0.5% of a water reducing agent, 2-5% of a thickening agent and the balance desulfurized gypsumpowder. According to the three-dimensional printing material, low-price desulfurized gypsum powder (industrial by-product gypsum) instead of high-price alpha-calcium sulfate hemihydrate is adopted asthe main raw material, sodium alginate and urea resin are added as the binder, and the anti-sticking agent, the water reducing agent and the thickening agent are added, so that the technical effectsof high early strength and short hardening time are achieved.

Description

technical field [0001] The invention relates to the technical field of gypsum materials, in particular to a three-dimensional printing material with desulfurized gypsum as the main raw material. Background technique [0002] With the rapid development of modern science and technology, the society pays more and more attention to production efficiency. Manufacturing enterprises must design products that meet more requirements and have higher cost performance within the shortest possible research and development cycle, in order to seize the opportunity in the fierce market competition. The development and trial production of new products using traditional manufacturing techniques requires a number of high-level skilled workers to use a variety of machining equipment and tools, which is not only costly but also long-term, and it is difficult to adapt to the rapidly developing market requirements. [0003] 3D printing rapid prototyping (Three Dimension Printing, 3DP) process is b...
