Hollowing Objects

[Anonymous]

If you want to skip the back story and what I've tried and researched you can skip to the last paragraph, but I'm trying to slightly hollow out a 20 sided dice to save printing time and resources.

I created a customized 20-sided dice for an assignment I'm creating for my classroom(tutorial I used https://www.youtube.com/watch?v=jdLCRtkI47c). Having never used Fusion 360 and never 3D printing before I've made significant progress. I am done with my design, but I am worried about the resources required to 3D print many objects. So to save the school (tax payers) money I want to hollow the dice a little bit.

I'm not trying to make millimeter thin walls, but trying to not have a solid core. Most of the tutorials I have seen make the object hollow in the beginning for the sketches. I have thought of going back to where I pulled each of the 20 sides into the middle of the dice and not pull each face into the very middle, but equally pull them partially to the middle, but that could leave certain points hanging in midair, which a 3D printer could not hold a point in place until it's connected it to the body of the object. The 3D printer where I teach does use the light method to cure the resin, so I do not think it will be too hot with a hollow object as I have read on past posts is risky to make. 

I was hoping there was a way to pick a plane(x, y, or z), create a center bodied circle in the middle of the dice on the chosen plane, turn it into a sphere,  and cut it from the body of the dice. Is this possible?

Looking at your last sentence request, use the Combine command, found under the Modify menu in the Design environment. This command allows you to cut (subtract), join (add) and intersect two bodies with each other.  As to what you want to design, I did not really follow your description.

I have a 20-sided dice created. I'm just trying to create an empty sphere in the middle of the dice so I don't use up resources.

yes, it's possible.  you pretty much described everything you need to do, have you tried it?  you can also make a copy and scale it down, and use that to core out the inside.  or you might do it one of a dozen other ways.

attach your file, and you'll get less generalized help.

You can do this two ways.  Create a sphere (using the sphere command) in the center of the dice and cut it from the die body or create a spherical body in the same location and Combine (cut) it from the die.

This is only a cube but I think it is what you want to do.

Just set the infill in your slicer to a low number.  It will work better than leaving an unsupportable void on the inside.  If you insist on making a void on the inside, a sphere is the worst shape you can use.  45 to 60 degree slopes would be much better.  Consider making the void like a cube standing on one corner.

For 3d printing a fully enclosed body, no windows, no access to the internals, (like printing Two halves,)

The 3d printing Slicer will do it for you.

When you Save As Stl, it will be hollow, check the preview,

you tell the Printer how thick to make the wall.

Usually to have Fusion do it, the Slicer fails.

Might help....
