Abstract

Laser powder bed fusion (LPBF) can rapidly manufacture the metal products with complex structures, but the high surface roughness and low dimensional accuracy limit the mechanical properties and application scenarios of powder bed process parts. Because in recent years, the ultrafast laser micromachining has shown great potential in the field of precision machining, it was combined with laser powder bed manufacturing. It means that after additive manufacturing samples, those were micromachined using ultrafast laser. In current study, a laser powder bed fusion device, equipped with a picosecond laser, is described, and a preliminary realization of additive and subtractive manufacturing based on pulsed laser processing using this device is presented. The side surface roughness of the samples fabricated by hybrid additive manufacturing process was lower than that of samples built LPBF technology. This study may provide a new way to manufacture parts with high dimension accuracy and low surface roughness by LPBF technology.
