my print is all supports and no model?

[ScenewithSyd 0]

I am relatively new to printing and I cannot for the life of me figure out what the problem is here. This model looks exactly as i need it to in the prepare space, but after checking the preview it becomes these weird spires. I have checked other slicers as well so I get the feeling its the model but im not sure what would need fixing. Ive made the model in Vectorworks 2024 and placed it into cura as a .obj file. Genuinely anything would be helpful.

Hi,

I dont know if you created this model, however, if you use a 3D visualizer you can see that the model is hollow inside.

This is a problem for CURA and the model can't be sliced properly.

 

If the model is yours, you have to solidify the object in some way (different softwares have different ways to do it), if the model is not yours, maybe it's possible to modify the STL file with other softwares, but i'm not an expert on that.

 

Aniway is a model problem and not a slicer problem. Hope this helps.

It's not just that it's hollow (though that's the main problem) - the model file itself is pretty bad:

Here's another screenshot (inside the front of the car) that shows the "hollow" problem:

 

I can't even get Cura to slice any more of it than this, so well done on that one:
