Investigation into spatter behavior during selective laser ...
The experiments were carried out on an SLM machine DiMetal-100, as shown in Fig. 1.A 200 W fiber laser (ytterbium-doped, continuous mode, TEM 00 profile and M 2 < 1.1, wavelength 1090 nm) was used. The building envelop is 100 × 100 × 120 mm.The scanning system used was a dual axis mirror positioning system and a galvanometer optical scanner, which direct the laser beam in the X- …
