Other reason: it’s simply a different circuit board that isn’t affected.
Yes, but you’ll only get the board if your current one has a malfunction. That means yes, your NTC has to fail (or other component) before they even consider sending you replacement. Also with NTC failure comes damage to the chasis so they’ll have to send it too in order for your printer to be “whole again”
Or use cool plate, biqu cryogrip and others that allow for lower heat requirements
afaik that’s up to firmware and indeed they could/should do that. Do note - in klipper that change is just a config file away 
Nah, A1mini is different AC Board design and the bed is 80C max on mini vs 100C on A1 while also being smaller. Oficially A1Mini power rating is 150W while A1 is 350W on 110V and staggering 1300W on 220V.
Side note: P1S shares the NTC component with A1 and I’ve seen like 2 reported P1S NTC failures, but those are very rare occurences.
Information about the A2L. Completely different hardware and design. According to CNC Kitchen, there is no longer an NTC Thermistor built in.

One could almost say that Bambu “lit a fire” under A1 owners to buy an A2 printer.

Pun aside, seems the A2L is really targeting the Cosplay community. New choice of using stickers instead of painting props or filament coloring. Stickers being much faster to create/apply and rapid changing for painted color selection. A whole new niche of considering sticker sets for common cosplay items. Who wants blood splatter patterns on their weapon wraps? Maybe a flaming sword ! Pun being, you build that on an A1?
I hope I’m not speaking too soon. I got my A1 in January 2024. It now has almost 1500 print hours.
After reading this thread I checked the printer (external check). No signs of melting or bubbling plastic, no smells, no smoke. When I feel the outside in the area where this thermistor is I can only feel a very slight increase in heat, which I believe it is due to the heat radiated by the heat bed. Actually the entire printer base feels like the same temperature.
One of these days I’ll venture inside for a better look.
One more for the group. I woke up today to a strong burning smell and my printer is completely dead. Luckily, it did not catch fire, as I could not have been here.
So now I am wondering what the next steps are. Should I contact support and risk missing my order deadlines?
I am in Canada and purchased it through the Canadian website exactly 14 months ago, so the warranty has just expired. If this is a recurring issue, it should really be addressed properly and covered, but I do not expect that to happen.
I will also be sharing this experience on my social networks. In the best-case scenario, where they replace the board, I still have a melted case, which will reduce the resale value of my printer. ;(
Contact support, and they’ll send you a replacement circuit board.
If you absolutely have to print because of a deadline, place the device on a fire-resistant surface and don’t leave it running unattended. We all know you shouldn’t do that, but with the deadline looming, you’ll probably do it anyway. At least be sensible enough to place it on a stone slab, for example.
However, I would advise against it.
I realise this probably isn’t what you want to hear, but if the device is already 14 months old, you shouldn’t really worry about its resale value anymore. These devices are budget-range anyway. Just keep using it until it breaks. Especially as a backup, in case you ever buy a new printer.

I purchased this Bambu Lab A1 in November 2025.
The printer suddenly stopped working during a print. I opened a support ticket, and Bambu Lab support instructed me to disconnect the printer, remove the bottom/rear cover, and take photos of the motherboard and internal electronics.
After opening it, I found that an electrical component inside the power section had exploded. Pieces of the component were loose inside the printer, and the surrounding plastic appears to have been damaged by heat.
This is not a normal minor failure. In my opinion, this is a serious fire safety hazard that could potentially result in a house fire, especially because the printer is designed to operate for many hours and is often left printing unattended.
I have sent Bambu Lab the requested video and detailed photos. I do not feel safe repairing or continuing to use this printer after such a catastrophic electrical failure.
Will Bambu Lab take responsibility for this defective product and replace the complete printer, rather than asking the customer to repair mains-voltage components at home?
I will update this post when I receive their response.
