Hello,
I am trying to print this 3D model, but nothing my friend and I do seem to work.
Any help would be greatly appreciated!
Here is a link to the file: https://grabcad.com/library/audi-r18-1
Thank you!

That's the issue with online repos, sometimes the files were made only to look nice. In that case inverted faces & non manifold meshes are not a problem.
Have you tried to run it through Netfabb ? Have you made an analysis in Meshmixer ?
What happened then ?
OK confession time, I'm 100% new to this.Quote:

I'm not an expert but all the blue lines mean to me the various surfaces not merged (I think). You need to go in meshmixer. Select a surface (use "expand to connected"), and then merge it to its neighbours, until everything is one continuous hole-less single shell. As it is, is it seems you have several unconnected surfaces close to each other.
That is what I meant saying that 3D printing models have additional requirements to "esthetic" 3D models.
Depending on the quality of this model, you're alsmot better off re-designing yourself.
That is also why curated repos for 3D printing and 3D designs databanks are 2 different things : not all 3D models are 3Dprintable.
Go to thingiverse or myminifactory or threeding or ... and you'll see.
I can't seem to figure out how to merge the surfaces, and when I tell it to fix errors on it's own it deletes almost all of the car.Quote:

Hi,
I'm more an industrial designer than artist. As such considering the complexity, designing this car is a couple hours work, tops - with the proper software. So, given the unknown quality of the file :I can't help you fix an STL, I don't really know how to : I make me own files and they work. Have you tried netfabb as suggested ?Quote:

EDIT : I see he has posted a STEP file. This is a much better quality file that should ensure a proper solid definition. Try to get that and mesh to make a STL : should work better. If you can't I'll give it a look.
OK, so I did look into it. I was astonished at 1st to see the audi logo and the "7" in the model. Then it confirmed what I said above. If you look at the 2 arrows, the model is not manifold (it is not closed and watertight). The designer basically designed the outer shell and a few addons but didn't bother to close : these are just planes standing in thin air, they have no thickness. Can't be used for 3D printing.
At this stage :
1/ You take it and close the holes (good luck).
2/ You look in a 3D printable repository for another one.
3/ You design it yourself. we can help for that.

Thank you so much for your help!
I suppose I might as well redesign it, as I need to make several changes anyways.
Where should I go for a very beginner-level tutorial on this?
Kind regards
