3-D MODEL MAKING

摘要

A method of and apparatus (1) for producing a 3-D model (35) by forming a contiguous 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 (42) of the 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 layer; and repeating steps a), b), and c), as required to complete the model.
