Check out our buyer’s guide for the best industrial and desktop SLS 3D printers. Includes SLS 3D printing services, technology overview, applications, materials, and more. Back in the 1980s, at the University of Texas in Austin, Dr. Carl Deckard and Dr. Joe Beaman developed and patented a manufacturing process called selective laser sintering (SLS). This was one of the first 3D printing technologies ever created, and over 30 years later, the technique is still being refined and advanced in a number of ways. SLS 3D printing uses a high-powered laser to fuse powdered material together into a desired 3D shape. This professional-grade technology is ideal for both functional prototyping and small production runs, as it offers a high degree of design freedom, high accuracy, and exceptional mechanical properties. Although SLS 3D printing was previously restricted to bulky and expensive machines, recent advancements have led to the development of more affordable and compact SLS machines. There are now a handful of desktop SLS 3D printers on the market, and even industrial-sized machines have become relatively inexpensive compared to traditional digital fabrication techniques. The ...
