Chemical resistant filament

Bambu Filament and Accesories Filament
1

I supply parts to a local car marufactuer, simply light and dashboard mounts. They have asked if I can design a piece to go on the brake cyclinder. The issue would be finding a suitable chemical resistant filament that would withstand brake fluid.
Does anyone know of anything suitable for this? or is this way outside of the realms of home printing.
Thanks
Simon

I would try petg and nylon.

Print a few sample pieces and just let them soak in some brake fluid for a couple days or even weeks and then check back.

They said “at home” so I wasn’t going to encourage the purchase of a 100-200 dollar spool of filament.

Thanks for the feedback, whilst I am sure the customer would pay for the special filament upfront, I only have a P1S and the PPS filament is only suitable for the X1 and latest Bambu printer.

A lot of printers -can- handle the more esoteric filaments but just are a lot more fiddly or have major drawbacks.

For example: A1 and A1 minis -can- print - say - ABS or Nylon but you have to figure out a way to deal with the fumes or temperature issues via a diy enclosure and ensuring their electronics can still get fresh air.

PPS does look like a possible solution. Do Bambu provide sample to allow me to test with the brake fluid first?
As for producing the parts I could try on my P1S but might need to find someone local with a X1 to make them.

The slight difference in bed temperature maximums is really the only difference.

I know people are going to say I’m a “worry wart” (and I totally am) but PLEASE think about the liability involved in making a part that has any interaction with the braking system of a vehicle. Remember the people who make parts professionally have all sorts of insurance policies to cover them.

Last year I was helping a guy at work try and make a part for his Spyder that would stop a 3rd party windscreen from flexing at high speed. I was on the 3rd iteration and I thought it was great, I used super strong filament and settings. The next day he told me he got up to 100mph, my part snapped in half and bounced off a car’s windshield. He slowed down and they proceeded to pass him while also flipping him off. That’s when I started thinking about what would have happened if my part had broken their windshield, then god knows what would have happened. I politely told him I just decided, at that very moment, that I wasn’t qualified to make motorcycle parts.

Again, just something to think about.
