# Which filaments bridge best / bridging settings?

These ranked rows list 190–260 °C (374–500 °F).

None of these threads names a filament that bridges best. The comments that address the failure say use supports, slow down, thicken the wall the bridge lands on, widen the line, or cool the PETG.

Change the support, the wall, the line width, or the fan before you change the brand. [Supports](/answers/supports), [PLA](/answers/pla_print), and [PETG](/answers/petg_print) are the settings pages. No thread here crowns a polymer.

## The rows

[PolyLite PLA](/brand/polymaker/polylite-pla) lists 190–230 °C (374–446 °F), a bed of 25–60 °C (77–140 °F), 40–60 mm/s, and the fan on. [ELEGOO PLA](/brand/elegoo/pla) lists 190–230 °C (374–446 °F) and 35–65 °C (95–149 °F). [Prusament PETG](/brand/prusament/petg) lists 240–260 °C (464–500 °F) and 70–90 °C (158–194 °F) from the Open Filament Database. [PLA](/material/pla) and [PETG](/material/petg) are the hubs. [Polymaker](/brand/polymaker) and [Prusament](/brand/prusament) are the brand indexes.

## Bridges and overhangs

[r/FixMyPrint 1jyzpt1](https://www.reddit.com/r/FixMyPrint/comments/1jyzpt1/) is Soleyin PLA at 210 degrees Celsius with a rough underside. The score-57 comment says use support, print slower, or cut the part in half and print each half flat on the bed. The score-13 comment says reduce layer height and increase line width, and says a 0.4 mm nozzle can go up to a 1 mm line because the overlap with the previous layer gets larger. 210 degrees Celsius is the post. 1 mm is the comment.

[r/prusa3d 1ojzuoe](https://www.reddit.com/r/prusa3d/comments/1ojzuoe/) is a PrusaSlicer bridge calibration. The filament pulls back before the bridge connects. The score-44 comment says the landing perimeter is too thin and may have shrunk away. The score-11 comment says the slicer is bridging along the walls because it does not see enough landing points, and says do not bridge onto one bridge layer. A score-3 comment says extra perimeters on overhangs fit this shape better than fighting the torture test.

[r/FixMyPrint 1hql799](https://www.reddit.com/r/FixMyPrint/comments/1hql799/) is PETG drooling under bridges. The score-11 comment says it is not cooling fast enough. A score-5 comment says blast the fan on those sections. A score-6 comment says the bridge direction may be across the gap and points at bridge angle. The thread does not name a PETG brand. The ranked PETG row is Prusament because it has a stored nozzle. It is not the spool in the photo.

[r/FixMyPrint 1h7vs34](https://www.reddit.com/r/FixMyPrint/comments/1h7vs34/) is dry, calibrated PLA. Overhang corners curl as the angle grows. The score-4 comment says too little cooling and too much cooling can both curl a corner, and leans toward slowing down so the part has time to cool. A score-2 comment says supports still leave an overhang, so the curl remains. Another score-2 comment fixed a similar PETG curl with the auxiliary fan at 50%. 50% is that comment.

[r/BambuLab 1lbn9wq](https://www.reddit.com/r/BambuLab/comments/1lbn9wq/) asks if a cantilever will print. The score-261 comment says use supports, and use gyroid or crosshatch instead of grid because grid crosses itself. The score-43 comment says grid piles up where the lines cross. The score-40 comment has PLA+ and has read about tree supports. That thread is an overhang. The [supports guide](/answers/supports) is the page for the support half of the advice.

## What the community says

r/FixMyPrint 1jyzpt1 is ugly undersides in Soleyin PLA at 210 degrees Celsius. The score-57 comment says support it, slow it, or split it. The score-13 comment says a wider line and a shorter layer. r/prusa3d 1ojzuoe is a PrusaSlicer bridge test where the end of the bridge does not connect. The score-44 comment blames a thin landing wall. r/FixMyPrint 1hql799 is PETG oozing under bridges. The score-11 comment says it is not cooling fast enough. A score-6 comment says the bridges may be running across the gap instead of along it. r/FixMyPrint 1h7vs34 is PLA overhangs curling. The score-4 comment blames cooling in either direction. r/BambuLab 1lbn9wq is a cantilever. The score-261 comment wants supports and gyroid or crosshatch instead of grid.
