Abstract Scope |
Diode Area Melting (DAM) is a new additive manufacturing technology which contains low optical power (~3.5W) output and lower wavelength (450 nm) lasers compared to traditional laser powder bed fusion (LPBF) with 1064 nm. DAM enables processing with independently addressable 450 nm blue diode lasers via connects to multiple fiber-coupled outputs in a single head which contains multiple spots. DAM helps to increase power absorptivity of metals in additive manufacturing process by using a shorter wavelength laser. In previous, DAM studies were held with 450 and 808 nm lasers with Ti-6Al-4V. This paper proposes a particular data set to literature as a combination of DAM and stainless steel 316L (SS316L). Besides, this work demonstrates an optimum process parameter window for single layer SS316L structures. Different laser process parameters such as scanning speed (from 50 to 500 mm/min), and hatch distance (0.2, 0.3, and 0.4 mm) are successfully optimized to obtain fully melt single track and single layer samples. |
