No filament on this page is called dishwasher-safe. The numbers below are heat-deflection temperatures from Polymaker's sheets. They say when a test bar bends. They do not say a basket, a detergent, or a dry cycle is fine. Whether plastic may touch food is food contact. Heat resistance and creep are the other heat pages.
Heat deflection, with the load named
PolyLite PLA, checked 21 October 2026, is 60 °C (140 °F) at 0.45 MPa and 58 °C (136 °F) at 1.8 MPa, ISO 75. PolyLite PETG is 78 °C (172 °F) and 75 °C (167 °F) on those same two loads. PolyLite ABS is 100 °C (212 °F) and 98 °C (208 °F). The 0.45 MPa figure is the lighter load. The 1.8 MPa figure is the heavier load. A part in a dishwasher is not that bar, and none of the three sheets uses the word dishwasher.
How to print polypropylene is the page for PP. It does not add a dishwasher rating either. PolyLite ASA's heat-deflection pair is on ABS versus ASA, and that page does not call ASA dishwasher-safe.
What the community says
a Reddit thread in r/prusa3d says PETG, if it is the right blend, will do on the top rack, that ASA is probably the better performer, and that PP is the other option if you can print it.
a Reddit thread in r/prusa3d says PETG yes, and that PLA will not survive a single round.
a Reddit thread in r/prusa3d says that if the part is not touching food, that person would not worry about food-safe.
Pros and cons
Pros
- Each heat-deflection pair names the load and the ISO 75 test, with the date the sheet was checked.
- No spool is called dishwasher-safe, because none of the cited sheets say that.
Cons
- A comment that PLA will not survive a cycle, and a comment that PETG will, are both comments. They are not copied onto the datasheets.
- ASA and PP show up in a comment. Their heat figures are not relabeled as dishwasher results here.
Printer considerations
- 0.45 MPa is the lighter load on the test bar. 1.8 MPa is the heavier load. A higher heat-deflection temperature means the bar got further before it bent. It does not describe detergent, spray, or a stacked cycle.
- Food against the plastic is [food contact](/answers/food-contact). Heat in general is [heat resistance](/answers/heat). Slow bending under a constant load is [creep](/answers/pla_creep).
- Comments that name PETG, ASA, or PP are experiences. They are not a manufacturer dishwasher rating. Polypropylene printing is [PP](/answers/pp), and that page does not add a dishwasher claim either.

Questions
So is PETG the dishwasher filament?
PolyLite PETG's heat-deflection temperatures are 78 °C (172 °F) at 0.45 MPa and 75 °C (167 °F) at 1.8 MPa. The sheet does not mention a dishwasher. A comment that prefers PETG on the top rack stays a comment. Food contact, heat, and creep are the related pages.
What about food safety?
A hot wash and food against the surface are different questions. Food contact, including what a maker has actually certified, is food contact. A comment that says not to worry when the part misses the food is not that certification.
