Single track formation in selective laser melting of metal powders
TLDR
In this article, the effects of the processing parameters such as scanning speed and laser power on single tracks formation are explored, and a considerable negative correlation is found between the thermal conductivity of bulk material and the range of optimal scanning speed for the continuous single track sintering.About:
