Heat resistant filament

Recommended Posts

Posted · Heat resistant filament

Hello,

 

I want to print a part that will be in a dashboard of a car, I've tried PLA but with some sunny days it melts...

The ABS looks OK, but it's very hard to print on my Fabtotum...

What is the best filament that I can use, that its easy to print and does not melt in a sunny day?

 

Thanks,

 

JS

Uhh, PETG has a higher transition glass temperature than PLA at 80ºC, while PLA is generally around 60-65ºC. Its also generally pretty easy to print requiring no chamber and emitting a standard amount of toxic gas.

There is also a more heat resistant PETG, like Colorfabb HT, which has a glass temperature of 100° or 110". But for the car, you are probably fine with normal PETG.

Up till now, all parts printed in transparent PET (brand: ICE, from Trideus in Belgium) and in NGEN (colorFabb) have survived well in my car, even in the hot summer of 2018. These can be printed quite easily, although NGEN is more difficult to glue with my cyanoacrylate glues.

 

And indeed, parts in PLA warp, even in mild spring or autumn weather.
