Editing Bambu Lab Authorization Control System

On January 16, 2025, the 3D-printer manufacturer [[:wikipedia:Bambu Lab|Bambu Lab]] announced that future firmwares for their 3D printers would introduce an authorization and authentication protection mechanism for their connection and control, in the name of security. Bambu has stated the following:<blockquote>''"This change is mitigating any risk of remote hacks or printer exposure issues that have happened in the past and also lower the risk of abnormal traffic or attacks."''<ref name="firmware-update-introducing-new-authorization-control-system-2">https://blog.bambulab.com/firmware-update-introducing-new-authorization-control-system-2/</ref><ref>https://all3dp.com/4/bambu-lab-limits-third-party-printer-control-with-new-security-update/</ref></blockquote>

== Controversy regarding firmware updates ==
[[File:Bambu tos screenshot.png|alt=bambu terms stating print jobs may not function properly if update is not performed to new firmware which is highly limiting. |thumb|Bambu terms regarding printer functionality & potential for disrupted print jobs if users do not update to a new firmware that radically restricts the autonomy of the owner of the printer]]

=== Potential for remote disabling of printers ===
A significant concern raised by the community revolves around the wording in Bambu Lab's [[Terms of Service]] and firmware update announcements. Critics and users argue that the phrasing leaves open the possibility for the manufacturer to remotely disable printers that are not updated to the latest firmware. Specifically, Bambu Lab's Terms of Service<ref>https://bambulab.com/en-us/policies/terms</ref> states that printers '''"may block new print jobs"''' if updates are not applied, which some users interpret as a potential pathway for forced obsolescence<ref name="firmware-update-introducing-new-authorization-control-system-2" />. While defenders of Bambu Lab point out that offline modes such as SD-card printing and LAN-only setups would remain functional, others point out that the Terms of Service do not explicitly limit this restriction to cloud-based printing. This ambiguity has led to speculation that Bambu Lab could enforce broader limitations, effectively rendering printers inoperable for users who choose not to update.<ref>https://old.reddit.com/r/BambuLab/comments/1i45iy2/bambu_lab_reserves_the_right_to_brick_your/</ref>

==== Editing of initial announcement ====
Bambu users were concerned they would not be able to utilize their printer if they did not install this update, due to the wording of the blog and the terms of service<ref>[[:File:Bambu tos screenshot.png]]</ref>. This caused confusion since users report that Bambu's blog post dated January 16th<ref>https://blog.bambulab.com/firmware-update-introducing-new-authorization-control-system-2/</ref> specifically says the following:<blockquote>
==== <sup>What happens if I never upgrade to this firmware?</sup> ====
<sup>You may continue using an older firmware version that does not include the new security updates; however, this means the printers may miss out on important security fixes or bug patches included in newer versions. We highly encourage updating to the latest firmware version for the best experience and enhanced security.</sup></blockquote>However, '''this was not present on the day of the announcement.''' A snapshot of their webpage from archive.is demonstrates this section did not exist on the day of the announcement, when community members voiced their concerns.<ref>https://archive.is/ejq3R</ref><ref>[[:File:2024-01-16-Firmware Update Introducing New Authorization Control System.pdf]]File:2024-01-16-Firmware Update Introducing New Authorization Control System.pdf</ref> Bambu's response to community feedback<ref>https://blog.bambulab.com/updates-and-third-party-integration-with-bambu-connect/</ref> references ''"social media posts spreading baseless allegations and untrue claims about Bambu Lab",'' including ''"Firmware updates will block your printer’s ability to print.",'' without mentioning the context for those allegations. The context for those allegations was the lack of inclusion of the ''"What happens if I never upgrade to this firmware?"'' in Bambu's initial announcement alongside their stated terms of service.

This announcement, after the edit in question, clearly states in the header - '''''Updated: January 17, 2025''' - to include additional details and FAQs where the '''What happens if I never upgrade to this firmware?''' among others was added.''

As per webpage oldest snapshot from '''archive.is''' <ref>https://archive.is/ejq3R</ref> dated 16 Jan 2025 17:31 UTC there are two references if choosing to stay on the old firmware:<blockquote>
==== <sup> Important Information for End Users </sup> ====
<sup>2. Old Firmware Option:
Users who decide to use an older firmware version can still use the previous or new versions of Bambu Studio and Bambu Handy without restrictions.</sup>
</blockquote>
Statement reads that user can choose to stay on the previous firmware and will not be punished for their choice by exclusion from access of first party updated software tools.<blockquote> 
==== <sup> Information for OrcaSlicer users </sup> ====
<sup> 1. You can continue using your X Series 3D printer with the older firmware version (which does not include Authorization Features). </br>
2. If you choose to upgrade to the firmware version with Authorization Features, you must download and install Bambu Connect (a printer control software)... </sup>
</blockquote>
Statement reads that users have the right of choice to upgrade or stay on the older firmware.

While FAQ section was added after the initial blog post publication:
* It appears to summarize unedited information available in the original article.
* Addition of the FAQ section, and as a result - editing the initial article, are clearly announced.

=== Debate over "bricking" terminology ===
''The debate has also "''extended to the definition of "bricking." Some community members assert that if a printer is unable to accept new print jobs without an update, it effectively becomes non-functional and qualifies as being "bricked." Others counter that as long as certain offline functionalities remain (such as SD-card printing) the term does not accurately apply.<ref>https://old.reddit.com/r/BambuLab/comments/1i45iy2/bambu_lab_reserves_the_right_to_brick_your/m7sezlg/</ref>

=== Privacy Policy issues ===
Bambu Lab's privacy policy, under "Personal Data that we collect," explicitly states: "3D Model in each client ('Printing Files') and other information related to the print job we may store, including start times, finish times, filament consumption and other relevant information."<ref>https://bambulab.com/en-us/policies/privacy</ref> This contradicts their claim that they do not monitor 3D prints. Additionally, the privacy policy webpage is notably excluded from the Wayback Machine, raising concerns about transparency and accountability in their data practices.<ref>https://web.archive.org/web/20250000000000*/https://bambulab.com/en-us/policies/privacy</ref>

=== Community Strategies to Deal with Risks ===
Users have discussed strategies to avoid possible disruptions, including:
* Operating printers exclusively in offline modes.
* Utilizing LAN connections or VPN setups: this requires an access key from the printer (previously, you could use your cloud credentials over LAN).
* Exploring alternative firmware or third-party scripts to restore full functionality<ref>https://old.reddit.com/r/BambuLab/comments/1i45iy2/bambu_lab_reserves_the_right_to_brick_your/m7t8i7r/</ref>.

== Bambu Lab's justification and rebuttal ==
Bambu Lab has stated that the authorization system is in place in order to protect against "remote hacks," "printer exposure," and "abnormal traffic or attacks." There are, however, several ways to mitigate these risks without the loss of user control that their system causes:

* '''The "remote hacks" that were cited as an example in the article seem to be a direct result of the 3D-printer vendor not responding properly to a reported security vulnerability in their product.<ref>[https://www.bitdefender.com/en-au/blog/hotforsecurity/someone-is-hacking-3d-printers-to-warn-owners-of-a-security-flaw?ref=blog.bambulab.com https://www.bitdefender.com/en-au/blog/hotforsecurity/someone-is-hacking-3d-printers-to-warn-owners-of-a-security-flaw]</ref> Therefore, in order to get attention, the researcher decided to infect machines and display a harmless message to spread publicity.''' Properly responding to security vulnerabilities, working to patch them quickly, and working with the security community (who would be more than happy to help secure products) would be some ways to prevent this.
* In the article cited about printer exposure, the hack was carried out largely because of user misconfiguration.<ref>[https://www.csoonline.com/article/566223/over-3700-exposed-3d-printers-open-to-remote-attackers.html?ref=blog.bambulab.com https://www.csoonline.com/article/566223/over-3700-exposed-3d-printers-open-to-remote-attackers.html]</ref> Printer exposure can be mitigated by offering more convenient ways to securely expose printers to the internet, so that users are not tempted to allow unauthenticated access over the network.
* The "abnormal traffic" can be mitigated by steps Bambu has already put in place, as detailed in their own article on the matter<ref>[https://wiki.bambulab.com/en/security-incidents-cloud-traffic?ref=blog.bambulab.com https://wiki.bambulab.com/en/security-incidents-cloud-traffic]</ref>.

== Issues with LAN mode requiring authorization ==

Bambu Lab printers have the ability to be controlled over both cloud and LAN. This allowed users to integrate their printers into private networks and maintain full control without having to rely on the manufacturer's server while also allowing cloud access. The new authorization system mandates that even LAN-based operations must go through an authentication process using Bambu Connect to retain full control.<ref name="bambu-connect">https://wiki.bambulab.com/en/software/bambu-connect</ref> Full local access is still possible and unchanged for those not using the cloud.

This change has drawn criticism for many reasons:
* '''Privacy concerns''': Requiring authentication for LAN mode raises concerns about data being unnecessarily exposed to Bambu Lab's servers, even for local-only operations, though previously, the printer was also connected and could be controlled by the cloud even when sending prints locally.
** Confidentiality required by US Law - This is in conflict with those that have to comply with 18 CFR § 3a.61, 32 CFR § 117.15, 32 CFR § 2001.47, and other restrictions.
* '''Loss of offline independence while also using cloud''': Before, users could have hybrid offline setups. The requirement for authentication removes this option unless users revert to older firmware versions, which Bambu does not allow people to do once they have updated to the firmware using the new scheme. 
* '''Increased complexity''': The added authentication layer complicates workflows for users who built custom setups or relied on third-party integrations for LAN control while retaining cloud functionality<ref>https://forum.bambulab.com/t/full-non-cloud-based-network-option-needed/3643</ref>.

=== Precedents and comparisons ===
Critics have likened this potential functionality to similar cases in other industries where manufacturers remotely restrict product features. Notable examples include [[HP]]'s printer firmware updates that [[HP Instant Ink|rendered third-party ink cartridges unusable]] and Tesla's software locks on second-hand vehicles. These parallels suggest a broader trend of manufacturers [[Retroactively amended purchase|using software to control hardware capabilities post-purchase]].<ref>https://www.classaction.org/hp-printer-lawsuit</ref><ref>https://www.wired.com/story/tesla-remote-disable-used-car-features/</ref>

=== X1E Firmware 01.01.02.00 LAN Only Connection "BUG" ===
Newly received X1E printers with firmware 01.01.02.00 will not connect to the Bambu Studio using the Lan only method password. Bambu Studio identifies the un-logged printer but will not allow a connection to the printer. Only after connection / account paring is done over the Bambu Handy app by giving internet access to the PC and Printer then utilizing the cloud service connection will Lan only communication and login work.<ref>https://forum.bambulab.com/t/connect-x1e-to-stand-alone-computer/101474</ref> 

== Implementation Timeline and Requirements ==

The authorization system will be rolled out in phases, starting with the X1 series printers. A beta firmware (version 01.08.03.00) was released on January 17, 2025, with the full release scheduled for January 23, 2025. The P & A series printers will get similar updates at an unspecified future date.

To use printers with the new authorization system, users must update multiple pieces of software:
* Bambu Studio must be updated to version 01.10.02.64 or higher
* Bambu Handy mobile app must be updated to version 2.17.0 or higher
* The new Bambu Connect application must be installed for using third-party slicers

These software updates are mandatory for users who update their firmware. Failing to update all components simultaneously will result in certain printer controls becoming unusable. Users who choose to maintain third-party software compatibility can continue using older firmware versions, though this will not be an option for new printers, which will ship with the authorization system pre-installed.

Bambu Lab states these coordinated updates are necessary because the new authorization system fundamentally changes how the printer validates and accepts commands. The older versions of Bambu Studio and Bambu Handy lack the authentication mechanisms required to interact with printers running the new firmware. The Bambu Connect application was created specifically to provide a controlled interface for third-party software, replacing the previous direct access through network plugins<ref name="firmware-update-introducing-new-authorization-control-system-2" />.

== Impact on third-party integration and user choice ==

=== Changes to third-party access ===
The new authorization system replaces direct network API access with a more limited URL-based interface through Bambu Connect. Third-party software can only interact with the printer by sending specific URL commands to Bambu Connect<ref name="bambu-connect" />. The interface requires three parameters:

* <code>path</code>: The absolute file system path to the 3MF file (e.g., /tmp/cube.gcode.3mf)
* <code>name</code>: The name of the file (e.g., Cube)
* <code>version</code>: A fixed value of 1.0.0 for compatibility

A complete command must be formatted as:

 bambu-connect://import-file?path=%2Ftmp%2Fcube.gcode.3mf&name=Cube&version=1.0.0

This interface only allows basic file transfer and print initiation. All other printer-control functions previously available to third-party software are now exclusive to Bambu's own applications. The path and name parameters must be URL-encoded using encodeURIComponent or equivalent functions<ref name="bambu-connect" />.

=== Reduced home-automation capabilities ===
While basic status monitoring remains available (e.g., print-progress updates in Home Assistant), the new firmware removes the ability for home-automation systems to control printer functions. Users can no longer:
* Start or stop prints remotely using Home Assistant, BTT Panda Touch,<ref name=":0">https://www.facebook.com/BIGTREETECH/posts/pfbid0SNZGxvf7NRdmyVgHf6y9yNedNbU2RrCfdT8gugTSD4AYfr5BHneNF9H1EbwyYiJEl</ref> or other third-party accessories or software interfaces
* Control printer temperatures or cooling
* Automate printer behaviors based on sensor data or events
* Access camera feeds through third-party applications<ref name="bambulab-forum-135400/9">https://forum.bambulab.com/t/this-new-auth-system-will-make-me-sell-my-printers/135400/9</ref>

=== Permanent nature of the update ===
Once a printer is updated to the new firmware, users cannot revert to previous versions that allows full control of the printer using LAN mode access key while signed into the cloud<ref name="firmware-update-introducing-new-authorization-control-system-2" />. The option still exists to disable the cloud service.

The manufacturer states this change is required for security, but community members note that many of the security vulnerabilities being addressed stem from Bambu's own cloud-centric design choices rather than inherent risks of local network control<ref name="bambulab-forum-134549/12">https://forum.bambulab.com/t/bambu-studio-1-10-2-public-beta/134549/12</ref>. The update forces users into using Bambu Connect middleware if they want to retain cloud functionality.

This can be characterised as a significant post-purchase reduction in functionality for existing owners who bought their printers with the understanding they could use third-party software and home-automation tools, but also only affects users actively choosing to use Bambu Cloud at the same time. The inability to revert these changes, combined with the mandatory nature of the update for new printers, is used to demonstrate how manufacturers can use software updates to unilaterally modify the capabilities of hardware products after purchase, although in this case the changes affect only people already choosing to use the cloud service<ref name="bambulab-forum-3643/9">https://forum.bambulab.com/t/full-non-cloud-based-network-option-needed/3643/9</ref>.

For users that would want to use a third-party slicer while using their cloud service, Bambu would require those users to download and install Bambu Connect in order to send gcode wirelessly over LAN or over the cloud. While Bambu claims that they were in contact with SoftFever, the developer of OrcaSlicer, as of writing, SoftFever still does not have any keys for Bambu Connect and the new firmware is only available as opt-in beta at the moment.<ref name=":1">https://x.com/fever_soft/status/1880630570809795034?t=qJyh4SGFZFllcYrqexGW-Q&s=19</ref>

== Impact on functionality ==
While some functionality remains unauthenticated like in previous firmware versions (sending status information from the printer over the network, starting a print job using SD cards), the most important features now require authentication through a new closed-source client called Bambu Connect<ref name="bambu-connect" />. These restricted features include:

* Initializing prints via LAN or cloud mode
* Remote video access to monitor prints
* Controlling motion system, temperature, fans
* AMS settings and calibrations
* Home automation integration beyond basic status monitoring

Previously, third-party software such as OrcaSlicer<ref name="orca-slicer-issue8063">https://github.com/SoftFever/OrcaSlicer/issues/8063</ref> could interact with Bambu Lab printers via the open-source Bambu Studio and proprietary network plug-ins. While Bambu Connect provides a limited URL-based API to initiate prints, most functionality previously openly available is now restricted to Bambu's ecosystem<ref name="bambulab-forum-135400/9" />.

Previously, third-party accessories such as Panda Touch would allow users to control their printers with a standalone device. Panda Touch was especially popular amongst P series printer owners since P series printers contain a monochromatic screen with a D-pad by default for printer control whereas Panda Touch is a full-color touch screen that had a small battery so that way users could reposition and detach their Panda Touch off their printers if needed. Users would be able to queue up jobs, jog printer motors, and connect to multiple printers at once in order to monitor print jobs. According to Big Tree Tech (BTT), the manufacturer of the Panda Touch, they urge users of Panda Touch not to update firmware any further since doing so would foreseeably permanently break compatibility with users' printers and their Panda Touch. <ref name=":0" />

== Communication with Panda Touch developers ==

As of writing, no formal communication has happened between Big Tree Tech (BTT), the manufacturer and developer of Panda Touch, and Bambu Labs. Based on their Facebook announcement, BTT stated that they have reached out to Bambu and will update if Bambu responds to their correspondence<ref name=":0" />.

== Communication with OrcaSlicer developers ==

Before the official announcement of the new authorization and authentication, Bambu Lab engaged with the OrcaSlicer development team regarding the changes. This communication has sparked significant discussion within the 3D-printing community, particularly regarding its timing, tone, and implications.

=== Pre-announcement contact ===
Reports from OrcaSlicer demonstrate that Bambu Lab provided limited advance notice of the changes that would render their software incompatible with Bambu printers running the new firmware. The communication emphasized:
* The introduction of Bambu Connect as the only supported method for interacting with third-party slicers.
* The discontinuation of the network plugin API that OrcaSlicer and other tools relied on for printer control<ref name="orca-slicer-issue8063" />.
* An invitation for OrcaSlicer developers to adapt their software to integrate with the Bambu Connect URL scheme.

The communication lacked the detailed technical documentation that would be necessary for developers to be able to work with the new requirements.  

=== How the community viewed these actions ===
This approach has been interpreted by many as a calculated move by Bambu Lab to enforce tighter control over its ecosystem. Primary criticisms of Bambu were:
* '''Lack of transparency''': The limited warning to OrcaSlicer devs suggests that Bambu Lab prioritized internal rollout schedules over community engagement with existing customers. Point to the contrary: the new firmware is in beta and Bambu Connect middleware contains temporary compomises to allow third-party slicers to work as before.
* '''Lack of follow-through:''' As of writing, SoftFever, OrcaSlicer's lead developer, still does not have API keys for Bambu Connect, a necessary layer of Bambu software that would need to be integrated into OrcaSlicer. Bambu's original announcement prominently mentioned OrcaSlicer and gave the impression that Bambu is actively providing the necessary assets so that SoftFever would be able to implement the new software architecture so that OrcaSlicer users are able to still use OrcaSlicer to send gcode to their printers without needing Bambu Connect to be installed as a separate program. The lack of active cooperation does not reflect favorably upon Bambu as it seems like their announcement used OrcaSlicer's name to try to make it seem like Bambu is trying its best to make sure that developers have what they need, but in reality, their inaction seems to show that Bambu is not making a sincere attempt to ensure that OrcaSlicer remains supported<ref name=":1" />.
* '''Disregard for open-source collaboration''': OrcaSlicer is widely used in the community; it is an open-source effort to improve the 3D-printing experience for all customers. By abruptly altering the compatibility landscape, Bambu Lab is seen as undermining good-faith initiatives to improve the ecosystem for everyone. The decision to restrict network APIs in favor of proprietary systems such as Bambu Connect represents a broader industry trend of closing off ecosystems that were once open, removing customer choice, privacy, and freedom.
* '''Token support for third-party tools''': While Bambu Connect provides a workaround for third-party slicer use, it significantly restricts functionality and complicates workflows, leading many to question the sincerity of Bambu's stated support for open-source tools<ref name="bambu-connect" />.
* '''Power imbalance''': As the hardware manufacturer, Bambu Lab has the ability to dictate how its products can be used; often to the detriment of third-party developers and users.

== Community-driven workarounds and technical alternatives ==

The 3D-printing community has begun exploring potential workarounds to restore functionality and user autonomy. These efforts focus on bypassing or mitigating the limitations imposed by the firmware update.

=== Custom firmware development ===
Discussions within the community highlight interest in developing custom firmware as an alternative to Bambu's official updates. One prominent project mentioned in forums is the development of custom firmware for the X1-series printers, such as the "X1Plus Custom Firmware"<ref name="bambulab-forum-134549/12" />. This firmware aims to:
* Restore direct network control and third-party slicer compatibility.
* Re-enable previously available features such as motion-system adjustments, temperature control, and AMS settings without requiring proprietary software.
* Provide users with greater flexibility in integrating printers with home-automation systems and workflows.

However, custom firmware development faces significant challenges, including:
* Limited documentation and proprietary hardware components, which complicate reverse-engineering efforts.
* The potential voiding of warranties and risks of bricking devices.
* Legal concerns regarding intellectual property and bypassing manufacturer-imposed restrictions.

== Backup of current third party access enabled firmware and network plugins ==
This GitHub repository contains a backup of all the latest firmware released by Bambu Labs for their printers and of the network plugin used by slicers such as Orca Slicer to communicate with the printer: https://github.com/Tzeny/bambulabs_plugins_firmware.

== LAN mode and blocked internet access ==
At the time of writing user Tzeny15 on reddit, has authored a five step guide to blocking internet access for the Bambu P1S as a precaution in case the manufacturer attempts to limit functionality for printers without the newest firmware. <ref> https://www.reddit.com/r/BambuLab/comments/1i4vp5i/lan_mode_with_live_view_remote_monitoringcontrol/</ref>

[[Bambu Lab LAN mode guide|Read the full guide here.]]

== Reverse Engineering Bambu Connect ==
{{:Reverse Engineering Bambu Connect}}

''[[Reverse Engineering Bambu Connect|Read more about reverse engineering Bambu Connect here.]]''

== Community tools and scripts ==
In addition to firmware alternatives, some users have come up with custom scripts and software tools to interface with Bambu Lab printers indirectly. These tools often rely on:
* Reverse-engineering the URL-based commands required by Bambu Connect to enable partial functionality with third-party slicers like OrcaSlicer.
* Creating local server emulations to replicate the network API previously available before the update.

While these tools provide temporary solutions, they don't fully replace the open ecosystem that existed prior to the authorization update.

=== Re-engineering printer-control electronics ===
ChazLayyd's Bambu Lab Klipper Conversion project is currently in an incomplete stage<ref>https://github.com/ChazLayyd/Bambu-Lab-Klipper-Conversion</ref><ref>DhazLayyd's Discord Community

https://discord.gg/W6B5mBejuC</ref>. While the project was not made in response to Bambu's announcement, there has been a wave of new public interest in this specific project. ChazLayyd's documentation instructs P1S owners to non-destructively remove the old control electronics that run Bambu's proprietary software and instructs P1S owners to install off-the-shelf control components so that the existing motor connectors and other critical electronics can communicate with the newly-installed off-the-shelf control components. 

=== Advocacy for open-ecosystem support ===
Community members have also organized to advocate for open-source support and rollback options. Suggestions include:
* Allowing an opt-out option for existing users who prefer local network control without cloud dependency.
** It should be pointed out that this has always been possible and past firmware updates made signing into the cloud at any point completely unnecessary. This information continues to be ignored by some.
* Providing an official API for third-party slicers under specific licensing agreements that allow secure authorized usage.<ref name="orca-slicer-issue8063" />
== Bambu corporate strategy vs maker community values<!-- the framing of this whole section comes across as quite opinionated, and it repeats a lot of factual information from earlier. reccommend cutting most of it, and reducing to a paragraph or two detailing the community response -->==

=== Impact on professional users and print farms ===
The restrictions imposed by the new authorization system create significant operational challenges for professional users who kept their printers signed into the cloud:

* Print farms can no longer use custom automation systems to manage multiple printers
* Workflows built around third-party software have to be completely redesigned
* The requirement to manually export and import files through Bambu Connect creates additional labor
* Integration with existing business systems and workflows becomes more difficult or impossible
* Professional users with more than 20 printers report the new workflow as "an absolute nightmare"<ref>https://forum.bambulab.com/t/this-new-auth-system-will-make-me-sell-my-printers/135400/4</ref>
The solution to the above is not to sign the printer into the cloud. Keeping the printer signed in would be a security oversight in this use case on the part of the print farm.

=== Privacy and data-collection concerns ===

The shift toward mandatory use of Bambu's software ecosystem raises several privacy and data collection concerns:

* All printer operations must now pass through Bambu's cloud infrastructure when using cloud mode
* User print data, including file names and print settings, becomes visible to Bambu when cloud is used
* Camera feeds and operational data are processed through Bambu's servers while on a different network
* Users have limited visibility into how their data is collected, stored, and used in the cloud
* The system creates dependence on Bambu's cloud services availability for basic printer functionality<ref name="bambulab-forum-3643/9" />

While Bambu Lab maintains that cloud processing is necessary for security and functionality, community members argue this represents unnecessary data collection that could be handled locally<ref name="bambulab-forum-134549/12" />. The company's cloud infrastructure costs are significant, leading some users to speculate that future monetization of the cloud services may be planned<ref name="bambulab-forum-3643/5">https://forum.bambulab.com/t/full-non-cloud-based-network-option-needed/3643/5</ref>. Therefore, people should assess if their use case mandates the use of the cloud service and disable it when it doesn't.

This shift from local control to cloud-dependent operation is part of a broader trend in consumer devices, where manufacturers use security concerns to justify increased data collection and reduced customer control over devices they bought and paid for. Privacy-conscious users should operate their printers in LAN-only mode to avoid cloud connectivity.

== Customer reactions ==

Customer reactions have been overwhelmingly negative.<ref>https://forum.bambulab.com/t/bambu-studio-1-10-2-public-beta/134549/4</ref><ref>https://old.reddit.com/r/BambuLab/comments/1i2psvz/firmware_update_introducing_new_authorization/</ref> Bambu Lab has historically pushed cloud-based printer interaction while offering limited LAN mode functionality<ref name="bambulab-forum-3643/9" />. Many customers argue that the security issues this locked-down firmware claims to address are actually consequences of the company's cloud-based design choices rather than inherent risks of local network control<ref name="bambulab-forum-134549/12" />, which continues to infuriate users who are now told that security is the justification for a loss of freedom. As a result of the announcement of the shift, customer ratings on sites like Trustpilot rapidly dropped<ref>https://www.trustpilot.com/review/bambulab.com?sort=recency</ref>, with many reviews citing the restrictions as the reason for the bad reviews.

The shift raises privacy concerns as user print data, including file names, print settings, and camera feeds, must now pass through Bambu's cloud infrastructure. 

Many community members and customers ask whether the significant costs of maintaining and deploying this cloud infrastructure might lead to future monetization of these now-mandatory services<ref name="bambulab-forum-3643/5" />, with subscriptions required for features that once worked with local access.

It should be noted, however, that so far '''no changes have been made or indicated for those not using the cloud service'''. Past firmware updates made it possible to avoid using the cloud service completely by allowing pairing the slicer via IP address and access key and doing offline firmware updates without having to sign the printer into the service, not even temporarily, keeping local functionality unchanged.

== Comparisons to similar practices by other companies ==

Bambu Lab's new authorization and authentication requirements have been compared to a number of practices by traditional printer manufacturers, such as [[HP]] or [[Epson]], who have also faced backlash around their handling of [[digital-rights management]] (DRM){{Citation needed}}. These comparisons address:
* '''Forced updates''': Firmware updates have rendered third-party ink cartridges incompatible, forcing users to purchase proprietary consumables.
* '''Restricted features''': Scanner/printer combos that will not scan if the ink is empty.
* '''Consumer backlash''': Users criticized these updates as anti-consumer, with some pursuing [[class action lawsuit|class-action lawsuits]] for deceptive practices.<ref>https://www.classaction.org/hp-printer-ink-firmware-lawsuit</ref>

Like 2D printers, Bambu Lab's update restricts functionality previously available to users and pushes them toward proprietary software and cloud-based control.

A parallel specific to the 3D-printing industry can also be drawn from the now-defunct 3D-printer manufacturer [[MakerBot]], whose shift from open-source, DIY-focused machines in 2012 to closed-source, proprietary machines (similarly to Bambu Labs), ultimately drove customers to less-expensive, open-source competitors.<ref>https://hackaday.com/2016/04/28/the-makerbot-obituary/</ref> MakerBot was also accused of asserting ownership over publicly available, open-source designs uploaded to its 3D print repository, Thingiverse.<ref>https://techcrunch.com/2014/05/28/makerbot-responds-to-critics-who-claim-it-is-stealing-community-ip/</ref> These factors contributed to MakerBot steadily losing their position and reputation as an industry leader, before getting absorbed by rival Ultimaker in 2022.
