Visiting Sinterit, the leader in compact SLS 3D printers, is always fun. Cracow, where the company is based, is a beautiful city and even the recent global tensions can ruin the welcoming atmosphere. It had been two years since we last visited to test and review their Lisa Pro machine. Then COVID came, just as the company began moving into the new, much larger facility. In the meantime, Formlabs, the market leader in the affordable SLA segment and Sinterit’s most credible competitor in the compact SLS segment, launched its machine after almost four years of announcements. The Polish company, founded by ex-Google developers and led by CEO Maxime Polesello could have been overwhelmed. Instead, the entire management team decided to focus on new product development and training for its employees. The result is that now, two years later, Sinterit is settled in a large new facility, with a highly organized assembly line, one ambitious product, Lisa X, hitting the market and one more, perhaps even more ambitious, NILS, getting ready to do so soon. When the opportunity came to do another test, this time with the Lisa X, I jumped and I was not disappointed.
