"Holes" in my top layers

[robinjsson 0]

Hey, I've had some trouble lately with my prints. Mostly it's the top layer that's missing some plastic..

At first I thought it was problem with Cura, that there was a bug or something that caused the printer to make unnecessary traveling moves (the blue lines), and therefore missing steps or something..

But I dont know anymore, maybe there's something else that is wrong. I got a picture of my latest print, where the "top layer" misses plastics. Does anyone know what the problem could be?

can you post your slicer settings? how many top layers have you selected?

this looks like either under extrusion or not enough top layers.

This print had 0.1 mm layer height and 0.8 mm top thickness.

What do you think causes eventual under extrusion?

Thank you for your help!

so what kind of printer are you using? your top layers seem fine btw..

You can have also problems with the file which can cause missing parts or just some pillowing effects.

But I think your problem is due to underextrusion ! Check your extruder first. Do you have a clean print to show us ?

Check your model to make sure it doesn't have errors in it by running it through

a model check like https://makeprintable.com/

I have a Wanhao Duplicator i3. I checked to see if the the nozzle was clogged, and yeah maybe it was, but I ran a print right after I cleared it and stayed to watch the printing.

There sure was an under extrusion..

I think it may have to do with my settings in Cura, started to try some new settings a week ago..

Yeah, watched my print yesterday and there sure was underextrusion.. Cleared the nozzle, but still no better print. Hmm, sorry, have no clean print right now to show, but about a week ago I was really satisfied with my prints.
