Cura and bridging

Recommended Posts


I have a Problem with slicing bridges by using Cura

I had this Problem since I stated using cura and I was hoping it will be solved with Cura 2, but it didn t.

First of all bridges should be detected, second bridges should be printed quite slow and with the Fan at max and the most critical, bridges should be printed straigt with "no infill".

the new cura detects and slices bridges correctly, sometimes. I have no Idea how I can trick Cura to do as I want to.

Yesterday I printed 3 models at once Cura sliced one corectly and two wrong as seen in this pictures



(sry no idea how to upload images propably)

did I miss any option or is there any trick?

I would love to see seperate bridging option in Cura in the future.

best regarts


ps. sry for my bad english ;-)

Could you upload the STL somewhere and provide a link? I think your bridge isn't perfectly flat and the sides are lower or something else about the bridge is confusing cura. For example, maybe the edges of the bridge have no support. Or maybe the sides are lower than the center. By a tiny amount not visible.

Try editing it slightly so that there is a clear bridge area. Maybe even have it two levels - one level to create the bridge and then .2mm higher have the rest of the bridge on top.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
