Selective laser melting metal 3D printing on a Renishaw AM250

Selective laser melting is a form of metal 3D printing whereby a high power laser selectively melts a region of metal powder. This process is repeated over multiple layers to create complex 3D geometries, not possible with traditional subtractive manufacturing.
Here a Renishaw AM250 is running it's calibration cycle.

what is that used for?

You can use SLM to make all sorts of components from aerospace to medical. In this case, this is just a calibration run to make sure everything is working OK.
