Messy Bridges

Plastic gets extruded over a gap from one point to another. When bridges are messy, the plastic strings sag. The plastic should be cooled very quick over a gap for a solid connection in-between. For an optimal performance, good calibration in bridging settings and cooling is needed. If the way is to far for bridges, use supports.

Bridges are difficult to make for the 3D printer. In most slicing programs there are settings for bridging. Plastic shrinks when it cools down. This is an advantage at the bridging, because the strings go up and make flat surface. Try a lower extrusion multiplier and a lower speed multiplier for better bridging behavior. More plastic would induce a drooped string. The next layer would hang down tooàbad bridging.
