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).

Oh my god enjoyed reading your article. I submitted your feed to my google reader!

What is the resistance of your heater? I don’t think my 8 Ohm heater could maintain the temperature if there was a heat sink cooling one end

I use a hollow threaded stainless steel tube as you appear to be doing. I do not have it screwed into a PTFE barrel at the top. I have it attached to an aluminum heatsink so that one end is held hot by the heater, and the other end cooled by the heatsink. This way the temperature drop is in the tube wall, and I do not need any PTFE. I used to use a TO-220 resistor. The first one worked very well (100 hours). The second and third were erratic (resistance would increase when it got hot, like there was a crack inside). I now use one of those Dale resistors with an aluminum body screwed to a little plate like you have. This heated is working very reliably.

Hi. I’m a journalism student at UWO in London Ontario and we’re doing a project on maker culture. If you’re up for it, we’d love to come and meet you and get some video of you and your machine in action. We’re planning a road trip for Sunday-Monday. Is there any chance we could meet you Sunday afternoon (Nov. 1)?

Thanks for your time and consideration
