AISI H13 tool steel structures were fabricated by selective laser melting which is one of the metal additive manufacturing process. Scanning speed of laser was controlled in the ranging of 100-1000 mm/s to optimize the process parameter to fabricate the highly densified structure. Laser power, hatch...
