Help
I am having real problems printing a model that I downloaded. The original model was an animation but I saved it as STL file in Blender, the model looked perfect. When I opened it in the Slicer and enlarged it look OK. I printed it (11 hours) and it printed the body ok but the from the shoulders it went wrong and the head was not join the body and the hair and cap was a mess.
What I have done wrong????
Best Answer by Neophyl:
If you are using Blender for models then you want to enable the built in Add ON called 3D-Print Toolbox. That will check models for issues before you export them. It can often repair things too. Not in this case though. That model has purely been designed for animation and not to be a real world item.
That tool also reports 22297 non manifold edges and 29768 intersecting faces. Non manifold edges are the thing that tends to make models non printable as an object should be a 'watertight' volume to slice properly. While slicers can repair lots of things most times they cant do miracles.
RE:
Can you save the file you sliced as .3fm file in your slicer and upload it here? (You might need to upload it as a zip file here)?
Could be a lot of things, hard to tell without knowing the file.
Mk3s MMU2s, Voron 0.1, Voron 2.4
RE: Help
I have attached the file

Attached Vanessa.3mf
RE: Help
I think you might need five posts before you can attach anything. May be wrong in that one. In any case it needs to be zipped by using your OS's standard compress function. The forum software won't accept regular 3mf files.

That model was not designed for 3D printing, the hair is an unprintable mess and PS reports over 20k errors. You might be able to replace the head if you are expert in Blender.
A regrettably common problem on TV and beginning to happen on Prusa Printables too.
Cheerio,

What you've done wrong is to ignore the yellow warning triangle next to the part's name and the notice at the bottom of 20K errors in the model.
Alas, I'm not a Blender user so can't say what you can do to avoid exports of defective STL files.
As a side note, even if the model had been without errors, a layer height of 0.05 mm is pointless with a 0.4 mm nozzle. It's not going to be better than 0.1mm and marginally better than 0.2mm. To see a real difference, you'd need a 0.25 mm nozzle — and be prepared for an exponential increase in print time...

I have tried to Repair the file in the slicer and have opened Windows 3D builder and tried to repair, it has been running for 24hrs and still not completed repair. I will advise if it finishes repairing.
Regards
Even if you repair the mesh the model will remain almost unprintable as the hair structure will be a fragile nightmare to support. Replace the head.
Cheerio,

RE: Help
Many thanks for the help, the repair has now finished and I have put it through the Pruslicer and it looks better.
But before I print it I will try the setting in Blender as Neophyl has suggested .

Magic
The repairing worked and I have just printed the results and they are OK.
Many thanks for all your help
