The effect of 0.8 nozzle on Ultimaker 3

[ITIMakerspace 0]

Its really urgent for me as am on my way to buy 2 new 3D printers

just asking if the build speed of Ultimaker 3 will rise from 16 mm³/s to 24 mm³/s "like Ultimaker 2" if I used the 0.8 nozzle or not?

Please its really urgent for me to know the answer for this question.

Thanks in advance for your time and effort.

Hi and welcome,

The build speed can increase when you use larger nozzles so yes it will increase. Not sur about the actual number but you can print higher layers and increase the print speed (or rather decrease the print time) with a 0.8 core.

Thanks a lot for the reply, but I am really in need to know the actual numbers, because its really will affect the purchasing process.

Looking at the default profiles for Beta Cura 2.7, here are your volumetric extrusion rates for the .8 Cores:

Fast .2 layer height X 35mm/s X .8mm nozzle = 5.6mm^3/s

Extra Fast .3 layer height X 35mm/s X .8mm nozzle = 8.4mm^3/s

Sprint .4 layer height X 35mm/s X .8mm nozzle = 11.2mm^3/s

You may be able to push it higher, but if you push too fast at too high a temperature, you could see heater errors.
