Hello all,
I was looking at the volcano nozzle and made some diy experiments. I drilled a spare nozzle to 1mm and gave it a go. The first layer is really good, and it’s fun to see how quickly a part is made with those thick lines. :slight_smile:

However the top layers are really ugly. They are wobbly and uneven, even on low layer heights. I have sanded some more from the tip of the nozzle, maybe as it moves that will smooth the plastic. I will continue experimenting with it.

Anyways, have you guys tried wide bore nozzles? I couldn’t find much information on it.
Cheers

Hi, yes I drilled one of my nozzles to 0.8mm and after some experiments this became my most used nozzle. It makes my prints so much faster and in most cases, the resolution is well enough for me. Maybe I can help you if you post some pictureas of your failed prints…

Great. I’ll make some pictures later today.
Did you change temperature or print speed compared to the original nozzle?
What layer height are you printing with?
Cheers

Yes, I print about 10-20 C° hotter as with my 0.5 nozzle. I usually use a layer height of 0.2-0.3mm. As my printer (prusa i2) is not the most stable one, I don’t print faster than 60mm/s, regardles witch nozzle I use…

So how much faster are the prints to say a comparable 0.4mm nozzle. I assume you choose the part t be printed based on whether it needs to be highly accurate or jsut functional?

here is one example calculated in cura:
nozzle: 0.4mm, layer height 0.2mm, shell thickness: 1mm = 1:52h
nozzle: 0.8mm, layer height 0.3mm, shell thickness: 1mm = 43min

On a 0.8 nozzle you can print perimters of 1.2mm thickness and layer height of 0.3 without problems. Slic3r gives u nice control options of extrusion width in the advanced settings…

I usually print functional parts with low detail for which a big nozzle is perfect I think. For detailed parts (like gears) I use my 0.5 or 0.35 nozzles…
