Abstract
Fabrication apparatus for fabricating an object as a plurality of successive laminae, the apparatus comprising: a nozzle comprising a precursor outlet for applying an aerosol or gaseous precursor onto a recipient surface; a heater for providing a temperature gradient along an application path of the precursor, so that the precursor is heated as it approaches the recipient surface and a transformation initiated so that a material layer of transformed material is deposited on the recipient surface; and a directable light beam for locally heating regions of the material layer so as to further transform the locally-heated regions to a solid material.
