Having Issues With Fill Density

[AzViper 0]

If I select 0% Fill Density the entire object is solid. If I print 100% its a solid while using 3.1, but if I use 15.1 with O% the item prints the way the designer has intended. Really bugged as I want to use the latest software.

It should work.  What did you choose for your wall width?  If you set that larger than your part size then it will have walls so thick it is also 100% filled.  I think a screenshot showing your settings and what your part looks like in slice view would be helpful.

Dang. That was the problem it was set at 4mm when it should have been 0.4. Thanks for pointing that out.
