Can I make Cura force the Ultimaker 3 to print everything with single filament on Ultimaker 3?

Recommended Posts

I have printed a model on an Ultimaker 2 and it takes about 2 hours. On the ultimaker 2 with the support made from PVA, the same print takes 13 hours.

Is there a way to make the U3 act like the U2+ and print the supports out of the PLA in order to speed things up?

Yes, it is actually pretty simple to do, just choose PLA as the support extruder:



Hmm! When I look at my version, Dual Extrusion does not show the choice for support extruder.


Am I looking in the wrong place???

If the support is coming from print core 1 will I no longer need the prime tower?

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
