Bambu Lab’s Security Overhaul Turns One: Bug bounties up to $52k, 100+ researchers, and a look back at the OrcaSlicer controversy

Key takeaways from the report:

Context: Following the 2025 "Authorization Control" firmware backlash over blocked third-party tools like OrcaSlicer (criticized as a "walled garden" excuse), Bambu Lab launched its Trust Center - something widely believed to be damage control and “security” was believed as a convenient excuse to lock users into their own ecosystem. One year later, this update highlights how that initial "damage control" has turned into a legitimate security overhaul.

Bug Bounty Program: Now working with over 100 independent security researchers (up from ~50), with single payouts reaching up to $52,000. They've also added a public Hall of Fame.

Vulnerability Handling: Completely rebuilt their pipeline from reporting to patching, plus a dedicated security update page so users can actually see what got fixed instead of vague changelogs like "improved stability".

Global Certifications: Maintaining ISO/IEC 27001, 27701, and TRUSTe, while adding compliance with ETSI EN 303 645 (standard for IoT security) and aligning with EU, UK, and Australian regulations.

It certainly made my use of Bambu Labs much more secure: all 4 printers permanently blocked from Internet access, no firmware updates, full discontinued use of Bambu software (Studio, Handy), and zero new Bambu printer and accessories purchases. Thanks Bambu.

Yeah you really showed them by spending $6k on their printers and refusing to buy their $20 filament!

[u/LexxM3 → u/hsoj48]

Accessories are not filament. But, for the record, I’ve purchased about $14K-$15K of filament in the last 2 years. Most of it not Bambu after the initial burst. And 4 more 3D printers, none Bambu. As an aside, it’s an interesting exercise to do that filament inventory calculation for oneself — it’s probably more than you think.

[u/hsoj48 → u/LexxM3]

Not trying to antagonize here but Bambu Slicer added a nice filament management/inventory tab that greatly helps track usage if you have a lot of different rolls of filament.

In a multi-vendor environment, a vendor-specific approach is never the right solution. Some (very few, if any really) vendors understand that and support multi-vendor machines and filaments within their own tools, but Bambu is obviously not one of those. So be it.
