Overhangs are where you’re printing a slanted surface without any support beneath. This is asking quite a lot of your printing, especially if you’re thinking of exceeding the 45° rule.

Signs of stringy and droopy overhangs:

Your overhangs should appear as smooth as the rest of your print if set up correctly. If they are looking more like the image shown, you’re experiencing droopy overhangs.


Stringy prints or droopy overhangs are usually a result of printing too hot or insufficient cooling. In a way overhangs are even worse to print than bridges. As bridges have a supported start and landing zone. The overhang doesn’t, it just clings to the neighbouring line.

How to fix:

  • Reduce your printing temperature in 5°C increments until your overhangs are smooth.

  • Increasing cooling (fan speed). If you’re already at 100%, you can ensure all chamber doors are open or add external fans to beside the printer. May not be suitable for all materials, check with the manufacturer/seller.

  • Tell your slicer to print the inner perimeters first before printing the outlines.

  • If you design your model yourself, avoid overhangs at an angle greater than 45°.

  • If the overhang cannot be avoided, consider using supports to hold them up.

  • Check your extrusion settings. Do the basic extrusion calibration of extruder steps/mm and extrusion multiplier.
