Abstract: Various embodiments provide a method of additively manufacturing a part including depositing a layer of a powder on a working surface, depositing a binder solution on the layer of the powder at first locations, and depositing a sintering aid solution on the layer of the powder at second locations. The sintering aid solution comprises a sintering aid in a solvent. In various embodiments, the sintering aid enables an increased brown strength as compared to parts containing unbound powder. The method enables binders that provide high green strength to be used at the edges of the part, while also balancing a shortened debind time with an increased brown strength. Embodiments in which binder solution is deposited according to a predetermined pattern at second locations are also described.

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 method of binder jet printing a part includes depositing a layer of a powder on a working surface and selectively printing a binder solution comprising a binder into the layer of powder in a first pattern to generate a printed layer. The pattern is representative of a structure of a layer of the part. The method also includes selectively printing a channel support agent solution comprising a channel support agent into the layer of powder to generate a green body. The channel support agent is selectively printed in a second pattern representative of an internal channel of the part. The method further includes heating the green body part above a first temperature to remove the binder and generate a brown body part and heating the brown body part above a second temperature to sinter the powder to generate the part having the internal channel generated from removal of the channel support agent.
