Prusa is still the most 'open source-ish' choice, but they're no longer a polar opposite to Bambu, in 2023 they started making efforts to stop commercialization of their designs, stopped sharing source/design material for their PCBs, etc. Then in 2025 they changed their 'open community license' to say users may not: “Sell complete machines or remixes based on these files, unless you have a separate agreement…” and “T…
It’s not problematic to restrict people from selling the thing you designed, made and sell without permission. If I make an open source car, I don’t want someone else taking my design work, and then selling a cheaper version of my product, I want my consumers to build their own parts.

Re: Bambu Lab is abusing the open source social contract
#102Bambu Lab has made plenty of mistakes, but I don't think this is one of them. And I'm a big supporter of open-source software. Their cloud infrastructure obviously has real costs associate with running it, and I don't understand why any software other than their own should be entitled to use those resources. If you buy something and then significantly modify it, you generally tend to void the warranty - and that's no…
That's not a genuine argument, nobody "feels entitled" to anything. Bambu made a deliberate choice to architect the product this way, deliberately placed themselves in this gatekeeping position, and they're deliberately working towards removing any other form of access to our hardware.
Re: Bambu Lab is abusing the open source social contract
#103They are offering a cloud infrastructure that allows users to remote control the printer via their software. If they don't want users to use a non-approved software to access their cloud, they should just build auth around it and explicitly tell people that. The accessibility for users to utilize the printer without going through official software and cloud is a whole other can of worms of course.
This whole fiasco could have been avoided by not being so confrontational, giving their user base ideological ammo.
Re: Bambu Lab is abusing the open source social contract
#104I am an outsider on the details of the Bambu software requiring users to go through their servers in China and the closing of their software. Still I suspect it is about spying in wartime, Bambu printers are at the core of the Ukrainian war effort, the main reason even Ukraine is winning since januari 2026. First China prevented Ukraine from using any of the drones that they sold in millions to Russia while exercisin…
Bambu had its requirement to go through their servers since before the Ukraine war, though it has gotten progressively harder to work around.
the Ukraine war started in 2014 technically. But even if we go to the "current" wave start, that was 24 February 2022[0].
Bambu Labs released their first printer (X1C, on kickstarter) on 31 May 2022, let alone their "must go through cloud service" restriction starting in early 2025[1].

Re: Bambu Lab is abusing the open source social contract
#105Full disclosure: I've never owned a Bambu because I've never loved the idea of a "closed" ecosystem 3D printer, however I have used them, and am very familiar with the 3d printing space beyond Bambu. For anyone considering alternatives: You should know that almost all other 3D printers expect you to know a little more about how they actually work than Bambus. Bambus are as close as you can get to a "just works" type…

#106Earlier quoted context omitted.
Prusa are pretty much plug and play these days, especially the Core One line-up. You're right that they're expensive but you get free human support 24x7, you get an open platform, lots of contributions to open source (even Bambu Studio is a fork of Prusa Slicer), and they pretty much go on forever. My Core One+ started its life as an original MK3 and went through each iteration of upgrades, and it works like new. I'm…
Is there any guidance on improving the Core One chamber? I would like to add some thermal insulation around the chamber, but I'm not sure if the firmware will properly detect unexpected thermal insulation in problematic scenario's, if it blindly assumes its a stock Core One... the more you modify a printer, the more it operates in terra incognita. Could too much thermal insulation cause the bed temperature to lower (…
The main issue is how close the walls are to the bed, which makes a lot of insulation projects dead in the water. If a radiator reflector foil [0] can be made to fit, it might help quite a bit as well.
Other than that, proper active chamber heating is really where we should be heading. When I have the time I might attempt to replace the left panel with one.

Re: Bambu Lab is abusing the open source social contract
#107My understanding is that right now, you can run your printer in LAN or USB mode without Bambu's cloud, and this is supported natively by OrcaSlicer (or any slicer using USB), but you lose some of the Cloud monitoring features.
You can also use Bambu's cloud with their Cloud Connect app and gain those monitoring features while using a third-party slicer, but at the expense that you send your prints through their cloud.
Or, you can use Bambu Studio and get the "fully integrated" experience.
My understanding is that this plugin just replicated their Bambu Studio communication with the Cloud, and that it _enabled_ you to send your prints to their cloud, not _disabled_ it. Is there something I'm missing that made this valuable? (ie - did it do some hybrid where it could hack in the Cloud monitoring without sending the prints through the Cloud?) Otherwise, I think what Bambu are doing are distasteful but I don't understand all of the Chinese espionage hand-wringing or "stealing our files" commentary around this.
EDIT: I finally got to the bottom of this; there is a cloud-based RPC method called `bambu_network_start_local_print` where Bambu's Cloud would authorize a print using (ostensibly) only locally transferred data. The goal of this project was basically to pretend to be the Bambu plugin in order to authorize this method, which is otherwise locked behind Bambu's auth system. This makes more sense. I wish the commentary on this subject would actually explain this.
Re: Bambu Lab is abusing the open source social contract
#108> Some people are okay with using OrcaSlicer and printing through Bambu's cloud. It's convenient if you're on the road and want to start a print on your printer at home Do such people really exist? Are there actually people who are comfortable blindly starting a robot in their home, with a part that heats to 150 C, and then hope that everything will work out and when they get home the part will be waiting for them, i…
Does your house have an HVAC system? Water heater?
It is closer to a toaster or an oven than a water heater or HVAC.
Also...my last lease specifically said that I was not allowed to use the washer/dryer or oven when I was not home. So it is not a stretch to believe that the property owners will use those types of agreements to go against you when the insurance company denies your claim (this does and has happened with 3d printer fires).
All that being said...I have run 135hr prints unattended on my printers (not bambu). The risk may be low but it is not zero and it certainly higher than a water heater or HVAC.
Re: Bambu Lab is abusing the open source social contract
#109I own a H2C and have been a huge fan of bambu for a few years, full disclosure. I don't really see why everyone is up in arms about this. You are able to print in LAN mode or directly through USB drives without going through bambus servers. Their slicer is open source but it downloads a plugin once you launch it if you choose to which is closed sourced that interacts with their APIs. Someone reverse engineered the pl…
> Someone reverse engineered the plug-in and put it into orca slicer and then claimed that the plugin should have been GPLed to begin with which I find dubious. I don't really see it being much different than downloading closed drivers on Ubuntu but I'm also not a open source lawyer.
The GPLv3 specifically was written to address a problem called "TiVo-ization", which is when a hardware vendor uses some trick (DRM, proprietary blobs, whatever) to prevent users from actually running modified versions of the software.
The AGPL, the license of this particular software, extends the GPLv3 with protections for users of network services:
> Simply put, the AGPLv3 is effectively the GPLv3, but with an additional licensing term that ensures that users who interact over a network with modified versions of the program can receive the source code for that program. In both licenses, sections four through six provide the terms that give users the right to receive the source code of a program.
https://www.fsf.org/bulletin/2021/fall/the-fundamentals-of-t...
And on TiVo-ization: https://en.wikipedia.org/wiki/Tivoization
The Linux and proprietary drivers situation is more complicated, but proprietary drivers on Linux are generally restricted to interfaces that Linux chooses to expose to them for that purpose. But the Linux kernel seems to take a narrower view of what constitutes a derivative work than was likely intended by the FSF in writing the GPL. Under a "traditional" reading of the GPL, those proprietary drivers are meant to be illegal. Whether some or all of the linking done by proprietary drivers in the Linux kernel is really allowed by the GPL or not is somewhat untested, I think.

> What printers are similarly priced and have similar specs, for someone relatively new to 3D printing? None, really. Prusa printers are good enough though. If you value freedom and privacy, its worth a few extra dollars.
It would have been so easy for Bambu to embrace freedom and privacy and continue to enjoy our loyalty all the way to the bank, but apparently they've got to burn down what they've got. I've got an a1 mini myself, and I'm not aware of anything comparable on the market, but there's a clear need for some competition now.
