Print on top area of existing part
I want to print a part with a 0.8mm Hotend, but on the last 1mm on the top the part needs a thin wall thickness. I want to use a 0.4mm Hotend for that last part. I could not use the other extruder, because it is needed for another material on the main print.
Is it possible to print on the top of the existing part with the 0.4mm Hotend? How could this be achieved?
Directly is not possible to print the top layers with a different hotend, but you can cut your model in the area where you want to print with the 0.4mm hotend and print them in dual.
you can follow this guide to do it: https://support.bcn3d.com/knowledge/design-print-dual
You can cut your model using your design software.
