Hi all, when using Cura I cannot figure out how to print my bridge hollow. Cura shows it hollow but prints a 2.3 mm solid bottom and at the top. Inhave tried raising it with supports. I have been placing it level with base at the bottom. Help!

Does the STL have a solid base? -
Do you have meshmixer? Simple to do a plane cut, or hollow, then plane cut. I am on vacation in Mexico, but if you need help with this, pm me and send file, it would take a few minutes on Monday.Comment

I can review and repair the file now if needed.

Make sure you are using a raft!

What is your setting for Bottom layers in Cura? It should be 0.

Thanks guys, I will try using a “raft”. My last attempt is better, using “spiralise Outer Contour” and disabling “Union Overlapping Volumes”. The walls are too thin, lolComment

When using a raft should the Bridge be on the bed or raised above?Comment

What version of Cura are you using? Not that it matters it is just different than the latest.
I use Wall Line Count and Top and Bottom Layers not Thickness. I have a rough idea of the thickness by looking at the Line Width under Quality? Use that to figure out the rest. For example I use 0.4mm Line Width. My walls are 2mm so 2 / 0.4 = 5 wall count. My tops are 3-5 layers and my bottoms are 0-3.
Personal perference, I don't use rafting it uses to much material. I like 10 count on brim.
Hope that helps.Comment

Oh ya don't use spiralise Outer Contour that will only give you 1 wall.Comment
