Print Accuracy/Quality (ie Nozzle)

Recommended Posts


The UM2 nozzle size is .4mm diameter.

Is there any other nozzle you can get that can halve this or less (<0.2mm).


Can you set the support Z distance less than the layer thickness but greater than 0?

How would you increase the quality of the side where the supports have to be?

Even with 0 distance and 40% density the support sides always turn out rough. Does it have to go slowly? say 20mm/s?

I dont really think you want to go lower than .4 mm. nozzle diameter... A lot of other things have a saying in the quality when you go that small... Also, it would take forever to print anything with smaller nozzle..

Regarding support, maybe look into making your own way in eg. meshmixer, or even straight in your modeling software
