The Translation: Bridging happens when your 3D printer has to stretch a line of hot, melted plastic across an open gap in mid-air, connecting two pillars without any support underneath it.
Use It In a Sentence: “I upgraded the cooling fans on my printer, and now its bridging is flawless without any sagging.”
Why You Care: Gravity is the enemy of melted plastic. If your printer is bad at bridging, the plastic will droop into the empty space and ruin the print. If a model requires long bridges, beginners usually have to turn on “supports” (extra plastic towers printed just to hold up the bridge, which you break off later).
