Selective laser melting (SLM) is one of many proprietary names [1] for a metal additive manufacturing (AM) technology that uses a bed of powder with a source of heat to create metal parts. Also known as direct metal laser sintering (DMLS), …

2019年8月1日 · Selective laser melting (SLM) is a common AM technique that is based on powder-bed fusion (PBF) to process metals; however, it is currently focused only on the fabrication of macroscale and mesoscale components. This paper reviews the state of the art of the SLM of metallic materials at the microscale level.

2021年1月1日 · Selective laser melting (SLM) is a powder-bed-fusion AM process whereby a high-density-focused laser beam selectively scans a powder bed and those scanned and solidified layers are stacked upon each other to build a fully functional three …

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。 在高激光能量密度作用下，金属粉末完全熔化，经散热冷却后可实现与固体金属冶金焊合成型。 SLM 技术正是通过此过程，层层累积成型出三维实体的快速成型技术。 LM 125 可选配成型尺寸 50ⅹ50ⅹ50 mm3 的加工小平台，可减少 80% 的粉末使用量。 设备结构紧凑、经济性较佳，适用于研发领域以及工业生产小尺寸零件.

SLM: Selective laser melting（选择性激光熔化）,是金属材料增材制造中的一种主要技术途径。 该技术选用激光作为能量源，按照三维CAD 切片模型中规划好的路径在金属粉末床层进行逐层扫描，扫描过的金属粉末通过熔化、凝固从而达到冶金结合的效果，最终获得模型 ...
