Lubricator for Ultimaker
by JPH, published
you might freak out of this idea but it helped me alot
I went from 100mm/s to 225mm/s (for simple objects)
and I went from 80mm/s to 150mm/s (for complex objects)
I spray oil in the bowden tube of my Ultimaker...... yes I do.
The Ultimaker is very fast because of the light weight on the hotend (as you know) But this comes with a down side, because at high speed the frixion in the bowden tube becomes bigger and this leads to filemant grinding.
To get the frixion away you need oil in the bowden tube but NOT on the extruder gear.
the oil did not seem to affect the print itself
-Small objects won't work at these speeds because the Ultimaker can't cool it that much yet

Here you go.
I did print it on its side because of the curve in the bowden tube side.
but you will see that.
It is not really the frixion but it's hard to explain.
the extruder feeds so fast that the filament bends inside the tube.
it's not a lot but at these speeds it works just a little bit different I think.
Ok I did a test to see where the oil goes.
I did that bij adding too much oil. (spayed 3 times)
And it did NOT evaporate, it sticks on the object.
Looks more shine and it brings the color up, actually pretty nice. :D
Also tried to wash it off but that didn't do it.
The object didn't get softer ore brittle it stays just the same.
(Really I can't believe it, it can't go better than this.)
I Have never testet ABS before so I don't know what it does to that.
So, Keramiek coat still seems to work good in all ways.
The text on the can says it works for metal and plastic.

difficulty print ***
Print support material: Yes
The things you need: 4x M3*10 screws
High Temperature resistant thin oil
The oil I used whas for my airgun: PTFE-/Keramik Coat.
Temperature resistant around -40C to +750C
but you can try different brands.
Make a small hole in the top of the bowden tube. But be gentle. you don't want the filament to get stuck when you push it through. A small hole is good!!! look at the picture to see what I meen.
than on top of that you screw the Lubricator on.
Only spray while you're printing!!!
one spay should do.
and your done.
Don't forget to make the temperature higher.
I'm printing PLA 150mm/s at a temperature of 240C!!!
One last tip..... don't listen to the screaming noise of your extruder ad higher speeds :D
