Nice to know. I’ll try this once I get my extruder up and running again. Does anybody know if this will work with olive oil?

Thanks for the post I broke a retainer ring this morning on my cupcake CNC because I was trying to force by hand. I have it rebuilt and oil is in place so I hope it will work out well.

I use peanut oil for pizza and stir-fry because it has a pretty high smoke point (232 degC).

Wikipedia has a list:

Safflower oil looks promising with a smoke point of 266 degC, too.

This is great! I will defiantly have to try this as I am having the exact same issue (using the 4042D from ultimachine as well).

The amount of oil consumed is very small compared to the amount of PLA consumed, so I don’t think it has a big effect. I have not seen the oil coming out in big clumps all at once. The parts I have printed feel very strong with no signs of layer delamination.

Good to know, thanks.
Do you have any problems with oil coming out through the nozzle, and maybe reducing adhesion between layers?
Maybe its good for the oil to vaporise?

Imagine how good it would smell if you smeared it with butter instead (probably not).
