Printing layer height 0.1?

Hey, I am new to 3d printing and I’ve been playing around with my new Taz 5. The things prints flawlessly at 0.25 layer height.

I was wanting to start branching out into high detail high resolution prints. I see that it can print as low as 0.1mm layers with the 0.5 nozzle. I tried a print and it was less than optimal. Some of it turned out ok, but I was getting what appeared like a extra drooping filament where I wasn’t supposed to such as internally between the cross hatching and drooping on over hangs. I have attached pictures. What is this? Am I printing to hot? To much flow?

I tried doing research and I found some stuff regarding calibrating line width to layer height with a 1.4 ratio… I dont even know if this is my issue. How do I go about calibrating such a thing? The only advice I found was to print a hollow cube with only a 1 pass shell. Measuring this and then adjusting the flow to compensate… Except I don’t even know how to print only a 1 pass shell as anything I try always does 2 passes.

Has anyone tried printing at 0.1 layer height before? Can it reasonably be done? What were your settings?

Thanks for your help and sorry for the bad image quality.

You need a highly dialed in printer to be able to print great at high resolution. Any errors are magnified at that scale. You probably want a cooling fan even for abs for those extremely thin overhangs and bridging. Go download every calibration object you can find, read every extruder calibration guide you can find, and when you can print any of those calibration objects perfectly, then and only then try super high resolution.

Dumb question of the day, with a .5 nozzle how can you print a layer at .1 mm?

The nozzle opening limits the minimum extrusion width… usually slicers set the layer width to 120% of the nozzle opening. When the filament comes out of the nozzle, its in a tube form. The Z-height can be anything from .075 - .5… anything above .5 and you’ll probably be printing in thin air. :slight_smile:

I like to compare to a tube of toothpaste. Hold it perpindicular to the counter, at a constant height squeeze and move the tube. Do the same experiment, this time squeeze lighter and move the tube lower to the counter. Should be a similar width, but lower bead of toothpaste.

Thank you, I learned something from your post about layers.
