Inner hole walls poorly connected

Recommended Posts

Hello Community,

since a long time I am reading in this very helpful forum but now I have to ask for tips and solutions aswell.

My inner holes are only poorly connected to the other layers. This happens only to horizontal holes, walls are not affected aswell.

At the beginning I had a lot of retraction problems (not enough filament after retraction, 100% filament flow only after some cm) and had to change the retraction distance to only 0.3mm. Not the beginning after traveling is uncomplicated... but the holes still have probelms.

My setup: Cura 3.0.4 and a Anycubic Prusa i3

Any suggestions?

Thank You,

Tim

Hi,

looking at the pictures you provided, the issue does not exhibit on all holes. The yellow print seems to have perfectly printed holes at the back of the model.

Maybe it is not a retraction problem (have you tried to prime more material at the start of a print and reduce retraction even further for the rest of the print?), but rather a temperature problem. Maybe the temperature is not stable and when the head is printing the outer walls of the holes and so the filament has a hard(er) time extruding.
