"Holes" in my top layers

Recommended Posts

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?

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


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..

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 ?


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.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
