The open loop system means the output of the system is free from their input. In the closed-loop system, the desired output depends on their input. The open loop system is called the non-feedback system while the closed loop is the feedback system. The control and controlled process are the two components of the open loop system.

The most important take-sway here is that if you choose a closed workflow system be sure that the system still allows you to export scan data in an "open" file format like the three just mentioned (.stl, .ply and .obj.) so that the scan data can be used and accessed by your manufacturing partners. They may charge you extra for this ability.
