Abstract
A method of and apparatus for producing a 3-D model by forming a continuous plurality of parallel layers of modeling material comprising a) producing a plurality of bead producing drops of the modeling material for deposition at desired locations b) controlling the locations and timing of deposition to produce vectors, in any and all directions required to produce an outer surface defining wall of said layer with a desired surface finish; c) adjusting the distance of the location of drop production to the location of drop deposition in preparation for the formation of a subsequent said layer; and d) repeating steps a), b), and c) as required to complete the model.
