Stereolithography. Most developed and most precise technology of rapid prototyping. It is based on the principle of polymerization of photopolymerizational composition under laser emission.
With the help of this technology three-dimensional object projected on computer is grown from photopolymerizational composition by consecutive thin (0,1-0,2 mm) layers, formed under laser emission on mobile platform immersed into the bath with photopolymerizational composition.
