Bridging
Also known as: puenteo · bridging · puentes · bridge · cruzar al aire
Short definition
Bridging is the printer's ability to lay material across a gap between two supports, with nothing underneath, and have it come out straight.
Full definition
When the slicer detects a gap between two supported points, it prints straight lines from one side to the other at a speed and cooling different from the rest of the layer, so the strand stretches and solidifies before it sags. The limit depends on material and cooling: PLA bridges very well, PETG is notoriously worse and ABS needs help. A sagging bridge is usually fixed by raising cooling, lowering bridging speed, or redesigning the hole as a teardrop rather than a circle.
Related terms
- OverhangAn overhang is the part of a model that juts out with nothing beneath to support it, measured as the angle from vertical.
- SupportsSupports are temporary structures the slicer adds under overhangs so material is not printed into thin air, and which are removed once the print is done.
- Layer heightLayer height is the vertical thickness of each deposited band of material, and it is the setting that most affects visible quality and print time at the same time.
