There is another important point, which is that FDM 3D prints are typically much weaker between layers than within a layer (anistropic due to the bonding). Havi

There is another important point, which is that FDM 3D prints are typically much weaker between layers than within a layer (anistropic due to the bonding). Having more control over the plane of the layers could open up some interesting design choices for functional parts.
