Is PLA compatible with propane?

Been working on a new forced air propane burner over the winter. Thought it might be cool to see if an air diffuser helped with mixing air/ fuel... so I 3D printed this in PLA.



The diffuser would sit inside a 2" steel pipe nipple, forced air/ propane fuel would blow through the 2" pipe before entering a 2" X 3/4" bell reducer then into the 3/4" X 8" pipe entering the furnace.

I have found no information whatsoever as to PLA and propane compatibility. I am not a chemist. The only long term test would be during a melt.

Anybody here in the know?

Any advice?

TIA

 

Give it a shot. You'll know pretty quick if it's worth casting one in metal.

 

I think it is, a quick search indicates that PLA can handle straight hydrocarbons fairly well, so propane shouldn't be any worse.
