SLM vs DMLS: Terms are frequently used interchangeably as both are laser powder bed fusion processes that fully melt powder. SLM emphasizes complete melting for maximum density. SLM vs EBM: SLM offers superior surface finish and finer resolution; EBM excels in larger parts with lower residual stress due to high build temperatures.
