Hi there !
I’m not 100% sure, but I think, that Polyester based materials (or PET, which is a special kind of polyester) are fuel resistant.
Can you specify, what the object is about ?
I could print this, if you are fine with splitting it once (I offer CAD services, so there would be no problem, to modify the model).
Example materials for Polyester and PET are:
XT
T-Glase
Alloy 910
PETG (i only use the three above, so I can’t tell if PETG will suit your needs)
Additional materials that SHOULD work:
Polycarbonate (known as “PC”)
maybe PMMA (the stuff that plastic glass is made from)
Nylons or Nylon-blends
I can’t guarantee, that those materials will resist fuel and other chemicals, but if you want I could contact the supports of the brands, that sell the mentioned materials.
I would highly recommend Alloy 910 by Taulman3d. This material is very durable and will ensure, that a printed tank won’t break (which is another problem that you might face beside the chemical safety).
To further help you I’d like to see the model that you want to get printed, also it would be good to know, for what the printed object will be used (a fuel tank in any kind of miniature vehicle?).
Disclaimer: I do only recommend materials, that might be fuel / petrol / hydrocarbonate resistant. Non of which is proven to resist to the mentioned chemicals.
Kind regards,
Marius Breuer
