3d print surface

[Printcar 0]

Hello people of the Ultimaker 3d community!

I have a problem printing my car model and was hoping one of you could help me. The car model is a surface made in Fusion 360. For some reason it is impossible to make the surface to a solid. I would like the model to be about 2 mm thick, but when you slice the model it will only print parts of it. Is there a way to fix this model?

"Your model is not manifold" error.

It can't be sliced because it isn't a solid and it's not closed.  You'll need to do something in Fusion to create a solid model.  I don't know Fusion but in other programs you could make a solid base and then do Surface Cuts and eliminate the areas that aren't part of the car.

Blender has several tools to fix problems like this automatically.
