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.
本发明公开了一种以脱硫石膏为主要原料的三维打印材料，由以下重量百分比的成分组成：海藻酸钠5‑8%、脲醛树脂0.5‑1.2%、抗粘剂0.5‑1.2%、减水剂0.2‑0.5%、增稠剂2‑5%和脱硫石膏粉余量。该三维打印材料采用价格低廉的脱硫石膏粉（工业副产石膏）而并非价格较高的α‑半水硫酸钙作为主要原料，通过添加海藻酸钠和脲醛树脂作为粘结剂，并添加抗粘剂、减水剂和增稠剂，从而达到非常好的早期强度高、硬化时间的技术效果。
