Trim tool issues

Is there was we can fix trim too cuts ? It’s doesn’t do neat cuts when you try to cut something in 90 degrees .
It’s super frustrating as I have to cut my sculptures in different part before 3d print and jonining them to one piece . These extra flang creates lot of sanding cutting works in production.

If you want sharp angles, then you should set boolean when trimming / splitting in the tool settings.
