Abstract: An apparatus includes a printing head (154) comprising jet nozzles (158) spaced apart from one another, where a distance from a first jet nozzle to a second jet nozzle positioned adjacent the first jet nozzle defines a jet-spacing, a printing head position control assembly includes a first actuator assembly (102) to move the printing head along the longitudinal axis and a second actuator assembly (103) to move the printing head along a latitudinal axis, and an control unit communicatively coupled to the printing head position control assembly. The control unit causes jet nozzles to dispense drops of binder (50) while the printing head traverses a first pass trajectory along the longitudinal axis in a first direction, indexes the printing head to a second pass trajectory along the latitudinal axis, and causes jet nozzles to dispense drops of binder while the printing head traverses the second pass trajectory along the longitudinal axis in a second direction.

Abstract: A binder comprises a monomer and an initiator. The monomer comprises at least one of a difunctional monomer and a monofunctional monomer. A method of manufacturing a part includes depositing a layer of particulate material on a working surface; selectively applying a binder in at least one of an edge of the layer of particulate material and an infill pattern representative of a stress of the object; repeating the steps of depositing and selectively applying to form a plurality of layers of particulate material with the applied binder; and exposing the plurality of layers of particulate material with the applied binder to an excitation source to decompose the initiator and initiate polymerization of the monomer to thereby form the green body part.
