| 摘 要： | 通过一种新型3D打印方法——3D凝胶打印,打印出不锈钢零件,并且对金属料浆的流变性能进行了分析研究。结果表明:固含量为61.5%(体积分数)的金属料浆具有较好的流变特性,适合3D凝胶打印技术;打印出的坯体表面质量较好,没有明显的分层现象;打印的不锈钢坯体在1 350℃保温1 h烧结后,相对密度可达95.7%。

Study on the 3D gel-printing method for stainless steel |

| Abstract: | A new 3D printing process,3D gel-printing (3DGP),was used to prepare stainless steel parts. The rheo-logical properties of metal slurry for 3D printing were analyzed. Results show that the metal slurry with solid con-tent of 61.5%(volume percent) has good rheological properties,which is suitable for 3D gel-printing. The green body prepared by 3D printing has good surface quality,and with no obvious stratification phenomenon. The stain-less steel body with relative density of 95.7%was achieved after sintered at 1 350℃for 1 h. |
