Abstract

A three-dimensional article making apparatus includes a processor operatively connected to a dispenser and positioner for constructing the article based upon the article defining data. The processor operates the dispenser to construct an enlarged surface of a first article portion to thereby define an enhanced target landing point area for dispensed droplets of build material for constructing a second article portion adjacent the first article portion. The enhanced target landing point area permits a slight misalignment or error that may occur between adjacent article portions. The processor also avoids shadowing during construction of the article by operating the dispenser to construct third and fourth adjacent article portions so that a dispensing path for constructing the third article portion is unobstructed by a previously constructed part of the fourth article portion. Related methods are also disclosed.
