Anyone using dual-nozzle setups for high resolution perimeters and low res infills? Something like 0.4 nozzle for printing perimeters with say 0.1 or 0.2 and 0.8-1mm nozzle for infill to provide strength?
This has been suggested so many times to this community. Something like a standard all metal hotend for perimeters and an E3D Volcano for infill. I think last time this was discussed there was no slicer capable of defining infill with a different extruder and nozzle diameter.
slic3r can be configured with different extruders, with different nozzle sizes, for perimeters, infill, solid infill, support material, and support interface material. Also, you can do infill every N layers instead of every layer. So you could do 0.3mm layers using a .4mm nozzle then using a .8mm nozzle print infill every other layer.
I stand corrected. Have you tried this?
I haven’t. The preview looks correct but I haven’t set up the machine I have with dual volcanos with different nozzle sizes.
People have done this on occasion with Simplify3D for ages, but it’s not common. Doesn’t seem like the time/resolution/strength improvement is really worth the added complexity and ooze management.
The CEL Robox does it stock though. It has needle valves in the extruders to stop ooze.
The problem I see is that 20% with a 1mm nozzle and with a .4 is quite different on the inside. Thinner nozzles provide thinner infill lines but more of them which can be advantageous. I used a 1mm nozzle when we printed out a lot of our printer’s parts and the infill wasn’t as good as with a .4 in my opinion. I would rather double the layer height for just the infill and run the same nozzle for the entire print.
