3D Printing News: OrcaSlicer Shut Down After Bambu Lab Legal Threats (Week of 2026-04-28)

The 3D printing world had a turbulent week. An open-source developer was legally silenced, Bambu Lab launched its next-gen dual-nozzle printer, China tested metal 3D printing in orbit, Nike dropped a new 3D-printed sneaker, and the EU courts handed Bambu a major legal win against Stratasys. Here's everything that happened.

🔥 Lead Story: Bambu Lab Shuts Down OrcaSlicer Fork After Legal Threats

The biggest story in 3D printing this week isn't a new printer or a breakthrough material — it's a legal battle that cuts to the heart of who controls your machine after you buy it. Independent developer Paweł Jarczak had been maintaining OrcaSlicer-BambuLab, a fork of the popular open-source slicer that restored direct printer control features Bambu Lab had disabled in earlier firmware updates. The project gave users back the ability to send prints to their own printers without routing through Bambu's cloud — a feature many felt should never have been removed in the first place.

Bambu Lab responded with a cease-and-desist letter, and Jarczak voluntarily shuttered the entire project. All releases have been pulled. The story has now been picked up by Tom's Hardware, Manufactur3D, and other major tech outlets, framing it squarely as a right-to-repair and open-source freedom issue. The community reaction has been fierce — this is no longer a niche 3D printing dispute, it's part of a much larger conversation about whether hardware manufacturers can use legal threats to lock users into proprietary ecosystems.

The irony is sharp: this happened the same week Bambu Lab's H2C was named "Best Premium 3D Printer" by PCMag, and a European court denied Stratasys' patent injunction against Bambu Lab. The company is simultaneously winning in the marketplace and the courtroom while alienating the open-source community that helped build the desktop 3D printing ecosystem. It's a tension that isn't going away anytime soon.
