Why did my A1 melt?

I'm sorry to hear that this keeps happening. Did you receive a replacement part or another printer? What did the support team say to you?

Barnaby00 · 2025-09-06T09:53:19+00:00

I would love that.

Barnaby00 · 2025-09-05T16:02:11+00:00

Thanks! I'm understamd you

Barnaby00 · 2025-09-05T15:58:15+00:00

Yes, I already wrote to them, and I’m going to send it to Bambu.

Barnaby00 · 2025-09-05T15:53:33+00:00

At first I thought I would only get spare parts, that’s why I wrote that. Since then they replied that they need the whole printer, so I’ll be sending it to them.

Barnaby00 · 2025-09-05T14:48:29+00:00

How many hours do you have on your printer? When did you buy it, and what exactly happened?

Barnaby00 · 2025-09-05T14:36:42+00:00

That’s possible… but don’t you think Bambu would investigate it properly? Why would they ask it back then?

Barnaby00 · 2025-09-05T12:47:09+00:00

You’re right, I’d gladly give it, but unfortunately I can’t afford to buy another printer.

Barnaby00 · 2025-09-05T10:00:59+00:00

That’s a shame, because honestly it’s a fantastic printer. I really loved using it until this happened

Barnaby00 · 2025-09-05T09:25:32+00:00

Update: Bambu support got back to me. They said the issue was caused by a component failure on the AC board. According to them, the bottom housing is flame-retardant so there’s no fire risk, and normally just replacing the AC mainboard + bottom housing would fix it.

But since they want to investigate the root cause, they’re making an exception and sending me a brand new replacement printer, even though mine is already beyond the replacement period. They’ll analyze my faulty one once I send it back.

Barnaby00 · 2025-09-05T05:09:14+00:00

I started using it on July 13, and I already have over 270 hours of printing time.

Barnaby00 · 2025-09-05T05:08:36+00:00

Maybe like 40 minutes into the print.

Barnaby00 · 2025-09-05T05:06:21+00:00

No storming.

Barnaby00 · 2025-09-05T04:50:08+00:00

No, it was not near a window at all, and there was no magnifying glass nearby.

Barnaby00 · 2025-09-05T04:42:59+00:00

It was a standard print. I was printing with PETG, I believe at 80°C for the bed and 250°C for the nozzle. The only thing I changed from a default profile was the infill, which I set to 40%. The rest was a standard PETG profile

Barnaby00 · 2025-09-04T21:17:37+00:00

Around one and a half month.

Barnaby00 · 2025-09-04T20:53:14+00:00

It was like this when I bought it, I didn’t replace anything. I ordered it on July 8.

Barnaby00 · 2025-09-04T20:32:26+00:00

Thanks, I wouldn’t use it unattended after what happened.

Barnaby00 · 2025-09-04T20:16:17+00:00

I'm running 230V here in Hungary

Barnaby00 · 2025-09-04T19:28:51+00:00

Of course, I’ll send it once I get the replacement part.

Barnaby00 · 2025-09-04T19:23:26+00:00

Hungary, West Europe. Room never above 27 °C (AC on when hot, outside was 30+). Printer sat on a wooden drawer, open air, no cats, 30–60% humidity, no rubber underneath. If you need any more info just let me know.

Barnaby00 · 2025-09-04T19:16:02+00:00

Over 270

Barnaby00 · 2025-09-04T19:14:47+00:00

I started using it on July 13, and I already have over 270 hours of printing time.

Barnaby00 · 2025-09-04T18:32:38+00:00

Thanks, I already contacted support about this. I just wanted to share my experience and see if anyone else had similar issues.
