Export 3d printing toolpath for blender

[Niklas_Ebert]

Hey guys,

I am currently doing a project with 3d printing.
That means all my geometries are based on curves.
If I want to export something for rendering it has to have a thickness right? So I tried just piping the whole curve, but that makes my exported .obj file 3GB big.

Is there a better way to export a geometry or a toolpath made of curves for rendering in blender?

I would really appreciate your help

Try making them mesh pipes.
You don’t need to get high-density.
If possible, share the file.
