Export Cura STL model into CAD

[inigo 0]

Hi,

Anybody knows how to export from Cura a 3D model with the inner infill created?

I am creating a functional prototype. I started with a part simulated as a solid. However for obvious printing time reasons I decided to use infill parameters.

I want to export the model that Cura creates (and transforms to G-code) back to my CAD software to simulate it and validate it.

Thanks,

Inigo.

What you describe is not possible

This blog talks about a few available options to do that:

How to Convert G-Code Back into STL

Hi DaHai8,

I did try to use the options about reverse code but it seems you can only get the outer shape in detail. The infill is not represented when you export it into stl and convert it back to a solid.

Thanks anyway.

I will write here if I find a tool to do it.

Hi Inigo,

Although this was years ago do you recall ever finding a solution to this?

 

Thanks

A long long times ago one solution was to capture the OpenGL stream. As Cura is using Opengl I suppose it still possible to do that.  I remenber some tests made with Acrobat3D OpenGL capture utility. But I don't know if this solution still exists.

Even OpenGL does not get the 3d model you see, with volume added to the extrusion lines. That volume is added with a GPU shader, and cannot be captured.

Finally for this type of studies there are one solution : Switch to PrusaSlicer. There, you can export the result of your sliced model into an OBJ file.
