Polish 3D printer manufacturer Sinterit has launched its free online 3D Printing Academy, and the premise will be familiar to anyone who has spent time in the AM industry.
For all the noise around 3D printing, genuinely useful knowledge about specific technologies is surprisingly hard to come by. The Kraków-based manufacturer found that professionals trying to make serious decisions about Selective Laser Sintering (SLS) adoption kept hitting the same wall: plenty of general content, and very little that was rigorous or structured enough to actually act on. Sinterit’s Academy addresses that directly, with three tracks built around where a participant is starting from.
The knowledge is practical by design. Participants gain the ability to choose the right 3D printing technology for their needs, evaluate printers against real business requirements, and approach SLS with greater confidence and technical depth.
“I think this is a fantastic resource for anyone who wants to dive deeper into understanding the complexities of SLS printing and get past the basic operations and functionality.” said Chris, a participant in the Engineers Track of the 3D Printing Academy.
Each lesson arrives by email, one per day, beginning immediately after registration. The materials span e-books, videos, infographics, podcasts, calculators, case studies, and practical guides.

Pick the Track That Fits You
The Fundamentals track is for anyone new to 3D printing, taking them through the history of additive manufacturing, how SLS compares to technologies like Fused Deposition Modeling (FDM) and Stereolithography (SLA). It also explains how the process works from first principles, an introduction to powder materials, and real applications across automotive, medicine, and education.
By the end of it, participants have a thorough understanding of the technology landscape to know where SLS stands and what it is genuinely capable of.
Next up, the Business track is aimed at managers, entrepreneurs, and decision-makers, working through the economic case for SLS, ROI calculation, the logistics of in-house printing versus outsourcing, concrete case studies, and an implementation roadmap. This module gives the participants everything they need to make a sound business case for SLS adoption.
Lastly, the Engineers track is the most technical, covering the physics of the SLS process, design optimisation for powder-based printing, parameters like laser power and scanning speed. The track also includes insights on powder management, post-processing, specialist materials including flexible and ESD powders, and mechanical property testing.
For engineers already working with SLS or planning to, it is a direct route to the kind of operational depth that is difficult to find elsewhere.
“The Academy materials fully met my expectations – they covered costs and workflows in detail.” said Learnmore, a participant in the Fundamentals and Engineers Track of the 3D Printing Academy.
Post-completion surveys show that participants appreciated the variety, and it is easy to see why: the formats that work for an engineer are not always the ones that work for a decision-maker.
A Decade of Distilled SLS Knowledge
The content was developed by a multidisciplinary team drawing on more than a decade of direct SLS experience, and Sinterit has been particular about writing everything in accessible language.
Early feedback suggests the effort landed. The programme has attracted CEOs, CTOs, engineers, designers, and operations managers, which is telling in itself. 3D printing is widely discussed, but structured, reliable knowledge about specific technologies like SLS is still genuinely scarce, and people across the seniority spectrum are looking for it.
Notably, completing all ten lessons and submitting a final survey earns a certificate of completion. Participants also get access to a closed LinkedIn community for ongoing knowledge exchange and an invitation to a live Q&A session with experts.
Carried through both its hardware and now this initiative, Sinterit’s argument is that SLS is no longer the exclusive territory of large manufacturers with large budgets. The 3D Printing Academy is the clearest expression of that yet.
