Filament for parts in engine compartment
Hello
I am designing an air intake plenum that will be in a 400mm diameter circular shape.
It will ontop of a fuel injection system so it is a quite touch enviroment.
Both heat and fuel vapour will attack the plenum
Is there any chance at all any kind of filament plastic can withstand this?
It can probably be around 100C (200F) here

You might consider researching ASA filament as a possibility.

hi-temperature pla will go up to 120c
There's the cheap stuff that you cure in a low oven and the expensive stuff that doesn't need curing.
Can't remember who makes the no-bake hi-temp pla.
ASA is basically a slightly modified abs - doesn't go any higher for temp tolearance.
Actually to a certain extent it depends on your printer.
If you have a top notch hotend that will do 300c, then polycarbonate is probably your best friend:
- rigid.ink’s Polycarbonate filament is an engineering grade, extremely impact-resistant thermoplastic. Perfect for a wide range of uses where you need one of the toughest plastics around, that can handle higher temperatures for demanding applications.
- With a Glass Transition of around 150?C your prints will hold their dimensional accuracy for temperatures up to around 120-130?C, but please be aware you need a hot end nozzle temperature of at least 280?C+. If you need a print to withstand higher temperatures, Polycarbonate could be it.
If you have a printer that can work with plycarbonate, then do so :-)
Then there's this stuff: https://eu.polymaker.com/product/polymide-copa/
Again, not cheap - but looks much easier to work with than polycarbonateLast edited by curious aardvark; 07-31-2019 at 02:38 PM.
