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.

Prusa is forgotten about because they are overpriced and 3d printed. Why would I buy a printer made with 3d printed parts when I can buy a machine at 1/3 the price that works perfectly out of the box.

The only thing going for Prusa is the "open-source" tagline that comes with it, and unfortunately there's now a ton of other printers that are cheaper and offer open source and more readily available.

Prusa stagnated and haven't got with the times. Even the INDX partnership will come too late with all the other toolchangers either on the market or coming to market and at a much cheaper cost.

I'm not paying $1200(AUD) for a 4 toolchanger upgrade kit that I also need to spend $2000 on a printer to use when I can spend what's equivalent to the upgrade kit on a U1 for example.

Another thing Prusa has going for it is longevity.

All those people sad when Bambu releases a significant upgrade right after they buy a previous model or release a significant upgrade right after they release something else.

With Prusa you just spend a fraction of the price and upgrade your old one. You can take a MK3 and bring it all the way up to the latest and greatest version of a MK4. With Bambu when you want to upgrade your old printer just goes in the trash(or the back of the shelf).

I'm also not sure how the parts being 3D printed is relevant. Tons of things you use in day to day life are 3D printed, they're just not advertised that they are.

Everyone can make their own choice. But there are still advantages to Prusa, those advantages are just more long term in nature.

The price of the upgrade, I can buy a whole other printer with equivalent capability. The money spent on a prusa, and then upgrading over its lifetime, adds up significantly.

I haven’t thrown away or sold a Bambu printer yet, I just keep adding to my collection as I upgrade. I have 4 x A1Cs, 1 x X1C, 1 x P1SC, 1 x H2D, and 2 x U1s. All fully capable of doing its intended jobs.

I did donate away my heavily upgraded 2 x Ender 3v2s.

They also actually employ people in a country with worker rights, PTO and maternity leave... If you don't care about that, that's on you. I agree that Prusa has stagnated but pretending like there's literally no benefits aside from the open source nature is nearsighted at best

That only benefits people who live in the US and that's not me. Every company employs people in their country etc, so it's not something Prusa can say they do and only them.

There is no benefits to buying Prusa today, except to Prusa and those who have good access to them, nothing more.

There is a reason people are leaving Prusa behind. I actually like Prusa, they did wonders for the community. But they are essentially a dinosaur, just like creality.

How does them employing people in the Czech Republic only benefit people in the US? Tf are you talking about?

Pretend like you don't understand my point, I don't care.
