/diy/ - Do It Yourself

a layer that fails is either an extrusion issue, like a an intermittent filament flow issue, particles in the filament could cause this, or your filament path is being constricted somewhere.... spool not turning when it needed to.... bowden tube bent into tight radiuses.... bit of grit in a bowden tube...etc.
or your stepper is overheating and layer shifting...
or your hotend is tilting becasue its not attached properly.

It's quite unlikely the model would break becasue one layer of filament didnt bond to the one under it unless one of the above, or your slicer sliced it with a full retard chunk missing. i often see this when exporting models from blender, boolean or mirror operations will flip the wrong triangle and orce will lose its shit for a few layers, until i fix the model and ouptut a new stl.
