printing assemblies errors

My students are designing desk organizers in OnShape and we have begun to print them on our Afinia 800 3D printers. However, everywhere two parts have been mated, the bond between the parts in the print is very weak. Like they were printed on top of each other and not as a single part. Their prints are breaking apart and it is disappointing to them after spending time designing. Any ideas on how to strengthen these joints? I found a discussion from 2016 in which another user was printing a model of an atom and had similar issues but there wasn't an answer that I could find.

Mate's define how parts interact so a fasten mate is just saying that in the real world these two parts are stuck together somehow. It's still up to you to decide how that is. Glue? Fasteners? Right now all we know is that two separate parts are stuck together somehow (the CAD system doesn't know at this point).
The slicer program is probably seeing them as two separate bodies (because that's how you've defined them in the CAD system) so it's not creating a continuous print path between the two. This is just my assumption without seeing/knowing more.
