3 Terms and definitions
The following terms and definitions defined in GB/T 35351 apply to this document.
3.1
Sedimentary layer
In the working state, the raw material melts under the action of the directional energy source, and the solidified layer is deposited on the working surface.
3.2
Sedimentary channel
In the working state, the area where the convergent point of the raw material and the energy beam is deposited during a single non-folding movement.
3.3
Deposition path
In the working state, the movement path of the convergence point of the raw material and the energy beam.
3.4
Overlap rate
Under normal process conditions, the ratio of the overlapping width of a part of adjacent deposition channels to the width of a single deposition channel.
