Since it was developed in the 1980s, selective laser sintering (also known as SLS) has been recognized for its ability to print polymer parts with high-quality finishes and good mechanical and isotropic properties. However, the technology’s associations have not all been so positive: SLS 3D printing is also known to be expensive—often prohibitively so.

 .

In recent years, one company in particular has attempted and succeeded to turn this notion on its head. Poland-based Sinterit has showed the additive world that SLS need not be a high-cost process: it is possible to make it accessible. But how? Why the high cost? Traditionally, the cost of SLS 3D printing has been cost-intensive for a number of reasons. First, the 3D printers themselves are expensive because of the integration of high-quality lasers and complex configurations. Most systems have also been costly to use and maintain because they require highly trained operators. Added […]
