This is effective when printing a difficult 3D printer overhang because there is less material being deposited with each pass of your print head. Less mass equals quicker cooling time . Second, change your shell settings/perimeters so that you printing from the inside out instead of the outside in.

Posted May 26 · Overhang Warping Issues. Printing multiple models improves cooling, but increases the risk of the curled-up parts being hit hard when the nozzles comes back from the other object. It depends on the geometry of the models. This testmodel was supposed to become a bridge, or table.

3D printing: Bad overhands and how to improve them When your printer has to make layers that go beyond the previous layer, it is called an "overhang". If your printer does not have sufficient cooling on the model, the section has difficulty staying in the air as the soft plastic must struggle with gravity.

Overhangs that are 45° from the vertical, or less, are almost always fine to print, the problems tend to start with overhangs at angles steeper than 45° from the vertical. Of course, the 45° “rule” is more of a guideline, as modern 3D printing technology can generally print steeper angles thanks to improved slicing software and cooling solutions.

For example, if a 3D printed tree’s branches were at too steep an angle, support structures would keep the form as close to the digital form as possible. A tree’s form, if 3D printed, would require...

If you’re having overhang problems, then you can try printing at the lowest possible temperature setting. This should make the filament material just soft enough for layer adhesion but not too hot that it cannot support its own weight.

Overhangs in 3D printing are where the filament your nozzle extrudes ‘hangs over’ the previous layer too far, to a point where it is in mid-air and cannot be adequately supported. This results in that extruded layer ‘overhanging’ and producing poor print quality, since it cannot form a good foundation underneath.
