Selective laser sintering (SLS) is one of the prominent methods polymer additive manufacturing (AM). A low-power source used to directly melt and sinter material into desired shape. This study focuses on utilization SLS system successfully manufacture metallic components through development a metal–polymer composite material. In this study, 17-4 PH stainless powders are mixed with polyoxymethylene (POM) high-density polyethylene (HDPE) prepare powder The polymeric mixture removed during thermal degreasing process subsequent results in solid component. Sinterit Lisa 5 W, 808 nm fabricate green part. For printing parameters 140 °C, power 35.87 mJ/mm2, layer thickness 100 μm, printed samples achieved maximum density 3.61 g/cm3 complete After at 1310 °C for 180 min, tensile strength shrunk sample 605.64 MPa, hardness HRC 14.8, average shrinkage rate 22%, 7.57 g/cm3, which can reach 97% theoretical density. allows use wide range particle sizes that usual AM technologies have, making it low-cost, low-energy-consumption, high-speed technology.
