Building an SLS system is more complicated than most realize. This is what SLS system manufacturers have been saying for years, five years to be exact, since the first SLS patent expired in February 2014. Then a few companies set out to change that myth and only one of them – so far – has succeeded: Krakow, Poland-based Sinterit. Its Lisa and latest Lisa Pro systems are real, reliable products. We had the chance to test and review their technology first-hand, after visiting the company in Krakow for a hands-on training session.
