Near net shape
Near net shape is an industrial manufacturing technique. The name implies that the initial production of the item is very close to the final (net) shape, reducing the need for surface finishing. Reducing traditional finishing such as machining or grinding eliminates more than two-thirds of the production costs in some industries.
Processes
The following are various near-net-shape processes categorized by material.

gollark: Yes, for obvious security reasons?
gollark: Well, a fancy asynchronous version.
gollark: ABR has that too.
gollark: It can also deploy bees, perform marriages in 102 countries, do arbitrary code execution, print fortunes, and bother people remotely.
