The practical process is based on the deposition layers of liquid photopolymers sensitive to ultra violet rays and almost simultaneously two powerful Uvlamps  ensure their hardening.

More precisely, a series of pumps carrying two resins,one that is used to build the model and the one that serves as support, from the cartridges to the tanks of the head.

The head shall give evidence in an appropriate resins. In particular, the resin "model" is deposited where there is the volume of the prototype, and the support is used to fill the cavity or to hold the inclined walls. This technique has the characteristic of gain of the areas whose roughness varies from 2-3 uM to about 15 mM, with very thrusts resolutions .
