Layer Separation

All troubleshooting pages are a work in progress.

Identifying Layer Separation

Layer separation looks a lot like warping except that it happens on layers other than the first one — layers of your print are warping off of each other, instead of off the build plate. This usually happens at sharp corners of your print, and is much more common with ABS and ASA materials.

Causes

Certain materials (ABS and ASAs) are prone to layer separation. This is because they print much better if they cool down slowly. As they cool they shrink slightly, and if that happens to certain parts of your print faster than others they’ll peal away and separate.

Solutions

Active Cooling

Turn off Active Cooling

Draft Shield

Print with a draft shield or enclosed build area

Layer Height

Print thicker layers

Active Cooling

Turn off your active cooling fans when printing ABS or ASA materials. This can help them to cool down more slowly, and stop layers from contracting too fast and separating.

Draft Shield

To insulate your print, you can print a draft shield. This will let your print cool down more slowly, and more uniformly. Draft shields effectively simulate an enclosed printing chamber and will not perform as well as a real enclosed build area (which can help with this issue as well).

Layer Height

Printing very thin layers (or with a very thin track width) will prevent layers from bonding well to each other, and can make layer separation issues worse.
