– Lower the printing temperature to reduce the flow of plastic.
– Increase the retraction distance to pull back the filament when the nozzle moves.
– Use a brim or raft to give the plastic something to stick to instead of your print.

Layer Separation

When the layers of your print aren’t sticking together properly, it’s known as layer separation. This can be a nightmare! To fix it, check out these solutions:

– Increase the printing temperature to make the plastic stickier.
– Slow down the printing speed to give the layers more time to bond.
– Use a glue stick or hairspray on the print bed to improve adhesion.

Importance of Maintenance and Calibration

Just like any machine, your 3D printer needs a bit of TLC to keep it running smoothly. Regular maintenance and calibration can prevent a whole host of issues. Make sure to:

– Clean the nozzle and print bed regularly.
– Calibrate the printer to ensure the nozzle is the right distance from the bed.
– Check the tension of the belts and pulleys to prevent skipping and layer shifting.
