Minimum Layer Height for Ultimaker 3 Extended

[inworks 0]

Hello All.

 

The Ultimaker 3 specs page lists 20 microns (0.02mm) as the least possible layer height with the 0.4mm nozzle (https://ultimaker.com/en/products/ultimaker-3/specifications). However, Cura (3.6.0) lists 0.06mm as the least possible layer height (i.e. the "Extra Fine" setting). This is what shows with the default Ultimaker 3 Extended profile with a AA 0.4 print core.

 

What is the reason for this discrepancy? Is it possible to print at 20 microns with the UE3? How? Is it as simple as entering "0.02" in the custom field? And why does Cura not show this as an option?

 

Thanks!

I never tried it, but I think you can. If it makes sense is another question, but you should be able to do it, as far as I know. The 0.06 is not a limitation of Cura, it is just a profile and you have the 0.06mm in the recommended tab as the lowest setting. But you can set it lower in the custom tab (Layer Height) to whatever you want.

Sigh... Yes... and.... yes.

(but you'll probably do not gain much - compared to the "Extra fine" profile)

Consider the Cura profiles as some presets that are well suited for the most common cases.

There's no specific preset for 0.04 either, none for 0.08, none for 0.12, none for 0.18, 0.03 and 0.19 are missing as well .... you get the idea...? 😏

make a little test with different layer heights yourself. All models are different and you choose what is best for your model. In general, layers under 0.06. are not getting better and take a lot longer to print, but in your case it might be different..??
