Selective laser sintering (SLS) allows for rapid creation of molds and prototypes directly in wax, enabling highly complex geometries. However, SLS faces challenges including slow build times, a lack of skilled designers, high material costs, and public misconceptions about its capabilities. Looking forward, SLS may enable more personalized and locally-produced manufactured goods through decentralized production networks and parametric design tools.
