this is an upgrade for the ultimaker to speed up your prints.

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


Please read all of the instructions before doing anything

difficulty print **
Print support material: Yes

High Temperature resistant thin oil
Some thin tape to make a good seal.

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 put some tape for a better seal.
and last but not least you snap the Lubricator on (it's a tight fit)

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

I had major underextrusion issues which I managed to solve by lubricating the bowden tube with PTFE (similar to what you're using). The results are great!
DO you keep using your Lubricator v1.1? What is your return on experience?
