Converting an OBJ into a solid

[Anonymous]

I am trying to print a figurine on my 3D printer. I created it in Humanmaker and exported it as a OBJ and was able to import it into Fusion360, but no matter what I do I can't make it a solid object to send to my printer. I am able to make surface objects but stitch can't put them together. If you can figure this out and then tell me how you did it, i'd be very appreciative.

Can you post the original .obj? (makes only sense if quad mesh)

Why would you not use Meshmixer for this?

The output of programs like your using are not geared towards printing physical objects.  they are for use in computer graphics/games/animation.  This file is a mashup of over 88 separate mesh "shells" or objects, most of which are just surfaces (meaning they are not closed and water tight).  look closely at the pony tail to see what I mean.  You'll never get that to print.

your best bet is to

-bring it into mesh mixer

-run a separate shells command on it. 

-get rid of things that can't be joined into a single solid

-repair he bodies you keep to make them water tight and printable

-maybe use the sculpting tools to get some of the detail you lost when deleting hair strands etc. 

-combine them all together

-possibly run a make solid command on it (will depend on your printer software if you need this)

There has got to be a way to make the mesh be used as a boundary as a cutting or filling tool. I tried Meshmixer and I can't get the camera to rotate correctly and I have no experience in sculpting. I can make nice objects in Fusion360 but this is kinda out of my league.

There is, but it will take a LOT of work to prep the file, and a good bit of knowledge about the nature of working with mesh models.  And frankly, fusion is the wrong tool for this job.  It's not particularly good at manipulating mesh models.

Why do you need to convert it to solid for 3d printing? Obj files are mesh files, directly you can open it in slicer softwares.

If there is a problem in the obj such as, it is not manifold, then you should use mesh mixer for filling the small gaps. If the gap is very big also requires modifications, then you can't fix it with fusion. You need something else.

Can you demonstrate all of this with the file that was attached?
