I should have added that my microwave also has a convection speed oven and can reach temperature of over 450°F.

What was the original made from? Did it have a recycling symbol, or does the replacement's website say?

@TheTridentGuysupportsUkraine it doesn't have a recycling symbol on it. None of the replacement parts specify what material it's made of.

I just came across another site which said:
PPS+GF40%,V0,XP. I believe PPS is polyphenylene sulfide but I'm not quite sure what the other information means or if it's even relevant.

According to multiple sources on the internet, PP is considered microwave safe and that's what most "microwave safe" plastic containers are made of.

But that's not the entire story. The best way to figure out if a material will deteriorate in microwave is, well .... microwave it :) If it survives prolonged exposure it's unlikely to have a problem as a mechanical part as it's not in contact with food.

Here are few Thingiverse models with claims (either by author or in makes) of being made from "good old" PLA.

How safe it is? Who knows.

Polycarbonate is the most temp-resistant material that's (just barely) accessible to amateur printers.

# What is an appropriate filament to 3D print a replacement microwave turntable ring?

(Asked by: username_0 on 2023-09-02)

I recently had the unfortunate experience of someone in my household accidentally breaking the microwave turntable ring. Considering the replacement cost of a new tray ring is upwards of $70, I'm exploring the option of 3D printing a replacement. However, I'm not sure which 3D printing material would be best suited for this task. Here are some key points to consider:

* I'm aware that certain 3D printers are limited in terms of filament compatibility, but fortunately, I own a Bambu Lab X1 Carbon that supports a wide range of filament types.
* Given the cost of the replacement part, affordability is a factor. I'd prefer a material that comes in at a lower price point than $70.
* Durability and heat resistance are crucial factors since the replacement part will be used in a microwave.

With these considerations in mind, could anyone recommend the most suitable 3D printing material for crafting a sturdy and heat-resistant replacement microwave turntable ring using the capabilities of a Bambu Lab X1 Carbon printer? Your insights would be greatly appreciated!

PETG is said to be microwave-transparent, and it holds 60 °C before softening (the ring would be printed, the original wheels should be used though), so it's a perfect and super cheap choice.

Even better, it's flexible enough so that the original wheels can be mounted with the flexible locking as in the original ring.

Keep in mind that PETG is more flexible than the original ring, so you have to make it wider.
