Oil helps PLA? Yes!
PLA is a material that we sell that is made of corn. It’s in the experimental stage, meaning that we did a bunch of tests and found it to be the best, but we haven’t found the best settings for it yet. One problem folks have been having is keeping it flowing!
Nick McCoy has solved one problem by coating the PLA with oil as it goes into the extruder. He’s put a piece of cotton and soaked it with oil so that it coats it as the filament goes into the extruder. Cool! We haven’t tried this out at the Botcave yet, but it’s refreshing to hear a cool solution! Learn more about PLA on the MakerBot wiki.
I am using engine oil, 10W-30, I believe. I bought the wrong stuff for my car once and so I have a quart of it lying around. I thought about using vegtable oil, but I think it would smoke at my working temperatures and I don’t need my reprap smelling more like waffles than it does just running PLA.
