So interesting… sorry for the question, rather than advice, but how do you do it? You print parts which could be put togerth? Or rather glued together? Have never printed, but want to try too
If printed object is hollow (no inner structure to support the shell), separating it into parts is needed so it doesn’t deform while printing (PLA filament is melted thus making it soft - unstable/deformed). Joints can be made as moveable or as you mentioned, to be glued… depends on intent (stop motion animation, toy or figurine). After parts are printed, hardened (and glued together) you smooth the surface using acetone and paint it (if so wished).
