Early this morning, a select few 3D printing YouTubers began receiving notice from Bambu Lab that all A1 3D printers should be turned off and not used until the company makes an official announcement. We reported on this “callback” notice on Jan. 28immediately after Bambu Lab announced “a very small portion of A1 printers” had a safety issue where the cable that brings power to the heated bed could become damaged and then lead to short circuits or power loss.
Tom’s Hardware did not receive this notice, and Bambu Lab has not responded to our request for clarification. We discovered the information on Twitter as members of the 3D printing community questioned why certain favored YouTubers were given advance notice of a possible recall before the general public.
We also learned that Micro Center, the brick and mortar technology retailer that sells Bambu Lab products in the U.S., has pulled A1 units from its shelves and will be accepting any models they sold back as returns.
“Micro Center’s top priority is ensuring the safety and satisfaction of our customers, we are accepting all customer returns of the Bambu Lab A1,” Micro Center Marketing Manager Laura Wall told us. “We have ceased the sale of the A1, pulled all A1 inventory from our shelves, and are in the process of returning all inventory to Bambu Lab.”
Grant Posner, President of 3D Musketeers, a professional 3D scanning and Additive Manufacturing business, with a YouTube channel under the same name, has long been critical of Bambu Lab’s safety and security measures. He asked Twitter“Are companies relaying safety information to influencers before making it public? Because if so, that seems like an issue.”
The email to YouTubers, shared in a blurry screen capturereads as follows.
Dear Partner,
Recently, Bambu Lab published a blog about the A1 Heatbed Cable, following a comprehensive investigation into unstable temperature readings and heating issues with our A1 printers. We identified the root cause of these problems as damage to the heatbed cable and provided solutions based on the cable’s condition, as outlined in the following link: https://blog.bambulab.com/a1-heatbed-cable-callback/
Though the feedback we have received so far indicates that the damage has occurred in only a small portion of the current A1 printers, we have come to the conclusion that we need to take further actions to minimize potential problems and risks for users when operating our machines.
Therefore, to safeguard the safety and rights of our users to the greatest extent, we advise you to refrain from operating your A1, regardless of whether your heatbed cable is damaged. We are currently in discussions to formulate the most appropriate solution, and will release our plan through official channels as soon as possible. We appreciate your patience.
If anyone inquires you about this matter, please kindly advise them to cease using the machine and await the official reply. Emphasize that Bambu Lab prioritizes user safety and is committed to providing the best solution for all users.
Once again, we deeply apologize for any inconvenience this may have caused you. If you have any further questions, please do not hesitate to contact us.
Thanks and Best!
Across the internet, on Twitter, Facebook, TikTok and Reddit, users have posted photos of their A1 cables. Many are concerned that they, too, have a damaged printer.
Twitter user @ZioFancoD told Tom’s Hardware that he had received a warning from Bambu Lab customer service to “cease using the A1 printer for now” after filling out a help ticket and submitting a photo of his cable.
“I am quite knowledgeable on printers and tinkering but wrote that I was not comfortable to replace the bed and wanted to know about the printer replacement,” ZioFancoD said. He posted a screenshot of customer service’s response on Twitter.
Bambu Lab still lists the A1 printer for sale on its website, but you can’t order it. The product description says it is “Coming Soon.” and there’s a button where you can ask the company to notify you when it becomes available.
When we reviewed the Bambu Lab A1 back in December, we gave it 4.5 stars and an Editor’s Choice award. In our tests, we found the bed slinger-style printer fast, easy-to-use and excellent and turning out quality prints. With its optional AMS, the A1 provides one of the cheapest and easiest ways to output multi-color models.
However, if you want a similar experience and don’t mind a much smaller print, 180 x 180mm bed, the Bambu Lab A1 Mini, which came out first, isn’t affected by the cable issue and hasn’t been recalled. This smaller product remains among the best 3D printers you can buy right now.
