SLM: Selective laser melting(选择性激光熔化) SLM技术是利用金属粉末在激光束的热作用下完全熔化、经冷却凝固而成型的一种技术。为了完全熔化金属粉末,要求激光能量密度超过106W/Cm2。目前用SLM技术的激光器主要有Nd-YAG激光器、Co2激光器、光纤激光器。这些激光器产生的激光波长分别为1064nm、10640nm、1090nm。金...
Selective Laser Melting, SLM) technology was first proposed by Froounholfer Institute in Germany in 1995, and its working principle is similar to SLS. SLM converts the laser energy into heat energy to mold metal powder. The main difference is that the metal powder is not completely melted dur...
