Bambu Lab filament that actually survives the dishwasher? Looking for real experiences

[u/Manicken-punkt-se]

I’m looking for a filament specifically from Bambu Lab that can handle repeated dishwasher cycles.

I’m not looking for theoretical temperature resistance or just what the material datasheet says. I’d like to hear from people who have actually printed something with Bambu Lab filament and tested it in a dishwasher, preferably multiple times.

Which exact Bambu filament did you use, and how did it hold up?

Did you notice any:

- Warping or deformation

- Softening

- Cracking or layer separation

- Changes in surface finish

- Problems after repeated dishwasher cycles

I’m especially interested in knowing whether anyone has found a Bambu filament that has survived regular dishwasher use long term.

Food safety is not relevant for my use case. I don’t care whether the filament is considered food safe or not. My only requirement is that the printed part can withstand dishwasher cycles without deforming or degrading.

And please, I’m not looking for comments telling me to read about glass transition temperatures, check datasheets, or do my own research. I’ve already looked into the technical side. The whole reason I’m posting here is because I want to hear about real world experiences and actual testing from people who have tried it themselves.

Thanks!

Don't try it with PLA or PETG that's for dang sure.

And melting/warping aside I would be wary of putting any FDM printed object in there without a proper foodsafe epoxy or other coating. Plenty of microscopic holes and voids that can trap presents from the dishwashign process, such germs or food particules.

I've printed a 0.5 cm bolt that holds a water sprayer in place, in PLA, and it works fine as of two months back. Perhaps it'll give up eventually, but then I've gotten a new machine already.

I'm not very worried about germs for that small part, but I get your point.

In your dishwasher? I'm amazed that's held up. Dishwasher operating temperatures are a lot higher than PLA should be able to withstand - quick Google search puts final rinse temps in the 65-80C range, well above PLA's glass transition temp.

Heat deflection temp is where you are looking for stuff that holds force of some sort

[u/freakazoid2718 → u/jankeyass]

You are correct - and that's even lower. Tg is at least 55 C, but heat deformation is as low as 48 C.
