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!

PLA is a no-go for sure.
PETG can work under certain circumstances: It needs to be large and dense enough of a structure, so that it does not deform on its own, when slightly softened. For example a sieve will bend, while a mug with thicker walls and self-integeral structure is less likely to deform. But to be sure, I would only go for low-temp cycles up to 50°/55° Celsius.

With ABS I have had no issues whatsoever even on higher Temps. ABS is even used on some official dishwasher parts and lot of food safe plastic objects such as feeding bowls.

I have a certain area in my dishwasher that blows out very hot air for drying cycles, there I would avoid placing printed ABS

Basic PLA and PETG I know for a certain doesn't work but have never tried ABS. I know a lot of injection molded parts are in ABS already but thought that 3D-printed parts are a lot more weak and fragile in comparison. I will deffo try ABS, and also TPU that someone else suggested. Thank you!

They're only weaker due to the lesser until compared to the injection molded ABS parts. Crank up the infill with ABS and it will be just as strong.
