Orientation

The position of an object relative to a coordinate system. It determines how the part is converted into layers of material, and impacts the supports needed, the build time, the strength of the part, and the surface finish.

Overhang

During 3D printing, overhangs are printed-part features that occur when a layer of metal is only partially supported by the layer below.

Overlap

During the 3D printing process, overlap represents the common area between two parallel melt zones.
