Application
This unit of competency defines the skills and knowledge required to develop and manufacture precision models where accurate and complicated models are required to assist in the development and manufacture of production of tooling for a wide variety of processes.
This unit can also apply to the inspection/completion of items made in the stereo lithography process.
When the programming of coordinate measurement machines and/or NC/CNC machines is required appropriate machine programming units should also be selected.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
