the energy source being concentrated, e.g. scanning lasers or focused light sources

Full Title

Additive manufacturing, i.e. manufacturing of three-dimensional [3D] objects by additive deposition, additive agglomeration or additive layering, e.g. by 3D printing, stereolithography or selective laser sintering > Processes of additive manufacturing > using only liquids or viscous materials, e.g. depositing a continuous bead of viscous material > using layers of liquid which are selectively solidified > characterised by the energy source therefor, e.g. by global irradiation combined with a mask > the energy source being concentrated, e.g. scanning lasers or focused light sources
