覆膜砂选区激光烧结后处理试验研究

Experimental Study on Post-treatment of Resin Sand by Selective Laser Sintering

摘要: 通过在激光烧结成型的覆膜砂试块上粘贴热电偶测温的方式，测量玻璃珠中试块的实际温度随时间的变化曲线，并测试分析相应的试块强度差异，对进一步优化激光烧结砂芯的性能具有实际参考意义。

Abstract: By sticking thermocouples on selective laser sintering coated sand specimens,the actual temperature and strength of specimens in glass beads were tested and analyzed. It has practical significance to optimize the performance of laser sintered sand cores.
