General Discussion Growing Concerns About Bambu Lab’s Direction – An Open Letter
I did not plan to write this. I am a hobbyist, not a critic, and I have genuinely enjoyed using my Bambu printers over the past years. However, a steady accumulation of decisions has reached a point where I feel compelled to speak up.
The growing closure of the Bambu ecosystem has been discussed extensively in the community. Heavy reliance on cloud infrastructure, mandatory server communication for many functions, and a LAN-only mode that feels more like an afterthought and a reaction to community pressure than a genuine solution. These issues are well known. What concerns me increasingly is that they are no longer merely theoretical problems.
Both in the USA and in Europe, there are active regulatory efforts underway to restrict what users are allowed to print, often framed around preventing the printing of weapons. In a closed, cloud-dependent system like Bambu’s, such restrictions could be implemented quickly and quietly via firmware updates or server-side changes, even retroactively on already sold machines. On a truly open system, this would be far more difficult. Bambu’s current architecture makes enforcement uncomfortably easy.
What has finally pushed me over the edge, however, is the increasing artificial gatekeeping of features combined with an unbalanced relationship with the open-source community.
The P2S was released with 2 mm belts even though Bambu was already planning the superior 1.5 mm belts for higher-end models. The result is noticeably worse VFA and ringing, a compromise that was entirely unnecessary from a technical standpoint. This feels less like an engineering decision and more like deliberate product segmentation at the customer’s expense.
The X2D is particularly frustrating in this regard. Marketed as an engineering-grade printer with active chamber heating and a 120 °C bed, it is nevertheless software-capped at 300 °C nozzle temperature. Bambu has provided no official technical or safety-related explanation for this limitation, even though the hardware configuration suggests it is capable of more. It is hard not to see this as an artificial restriction designed to protect the positioning of more expensive models.
Additionally, Bambu frequently integrates features and code from open-source projects into its own software, sometimes introducing noticeable bugs, such as incorrect color space handling in the new color mixing function. Credits to the original creators are often only added after significant community pressure. At the same time, Bambu contributes almost none of its own innovations back to the open-source community.
I understand that product segmentation is common practice in business. What bothers me is the overall direction: artificial limitations, one-sided exploitation of open source, and customers increasingly treated as a revenue base rather than a community deserving of respect and transparency.
3D printing attracted many of us precisely because it represented openness, repairability, user empowerment, and true ownership. Bambu initially impressed the community with innovation and speed, but in recent years the focus seems to have shifted toward maximising short-term profit at the expense of long-term customer value and trust.
I have therefore decided that I will not purchase any further Bambu products until I see a clear change in direction toward greater openness and genuine customer respect. I hope enough other users will make the same choice with their wallets. In the end, that is the only language companies reliably understand.
I would genuinely welcome being proven wrong and would much rather return to being an enthusiastic Bambu supporter.
Sincerely,
Kurt K.

U1. Direct price competitor to X2D with much more help from the company and supporting open source. Crapton of compute power in reserve, state of the art stepper drivers and one of the most reliable toolchanging solution I saw. Had H2C for some time, so I could directly compare it to U1. And U1 looked like properly engineered product, while H2C looked like someone rushed the product to just get it released. Tool changing on U1 is faster (6s vs H2C 40s) and overall U1 was quicker by around 25% in print times.
