I wonder what could be the cause of all these little bulging imperfection? This is an Abs print.
its a flow issue slightley to much material or imperfections in the material used reacting to the heat basicley mixture taking longer to cool so it continues to flow out wards idk some food for thought
@steveklloyd first the filament brand play a big roll in quality print? But if it is the flow issue how can I improve it? Does doing calibration improve it?
This is caused by your slicer. You’ll want to end extrusion a little sooner, and ‘wipe’ the nozzle with the excess. These are just blobs from ending the layer line. Can get removed pretty easily in your slicer.
It looks like z banding to me. Do you have any vibrations or motion on the z axis while printing.
wow look at what david said and Thantik could be either of those as well good advice
