The problem with current selective laser sintering (SLS) printers on the market is that they cost over $10,000. Our goal is to create an affordable SLS printer marketed for hobbyists. SLS printers work by scanning a laser over a bed of powder and fusing the powder particles together. A new layer of powder is added to the previously sintered layer and the process continues to create a three-dimensional object. SLS printing allows for higher complexity and higher tensile strength prints compared to the conventional FDM printer. Our prototype will prove that affordable SLS printing is possible which will help broaden the world of additive manufacturing.
