The Smooth-Geometry is the optimisation result without any intersection. If you have added Machining Allowances or the automatic Non-Design surface growing growth is activated (default), the geometry will extend beyond the boundary limits from the Design Space in areas of Non-Design Spaces. This Geometry should be used for a Retransition retransitioning to a NURBS-Geometry. This Geometry is very suitable for an intersection between the retransitioned optimisation result and the Design Space. If the optimisation contains Retained Volumes, these will also be part of the Smooth Geometry.
The Print-Geometry is the Geometry which can be directly manufactured. It includes the extra material from the applied Machining Allowances which can be removed in a precise machining process like milling.
