Abstract: An embodiment of the present disclosure is directed to an indirect printing apparatus. The indirect printing apparatus comprises an intermediate transfer member comprising a substrate and a surface layer disposed over the substrate. The surface layer comprises a fluoroelastomer-aminosilane grafted polymer and infrared absorptive filler materials. The indirect printing apparatus also comprises a coating mechanism for forming a sacrificial coating onto the intermediate transfer member and a drying station for drying the sacrificial coating. At least one ink jet nozzle is positioned proximate the intermediate transfer member and configured for jetting ink droplets onto the sacrificial coating formed on the intermediate transfer member. An ink processing station comprises a radiation source for at least partially drying the ink on the sacrificial coating formed on the intermediate transfer member. The indirect printing apparatus also comprises a substrate transfer mechanism for moving a substrate into contact with the intermediate transfer member.

Abstract: A method of additive manufacturing includes jetting liquid material on a workpiece defining an uphill local surface and a downhill local surface. A printhead moves relative to the workpiece in a process direction, over the uphill local surface and the downhill local surface. Liquid material is jetted from the moving printhead onto the uphill local surface of the workpiece at a first predetermined spatial resolution. In a first approach, the printhead is controlled to refrain from jetting liquid material onto the downhill local surface of the workpiece. In a second approach, a local slope of the workpiece is determined, and a spatial resolution for jetting liquid material onto the local surface is determined as a function of the local slope.

Abstract: An ejector of liquid material to form spherical particles includes a crucible for retaining liquid material, an orifice area defining at least one orifice, and an actuator responsive to a voltage signal for causing material to be ejected from the crucible through the orifice. A method comprises applying a voltage signal of a first type and a second type to the actuator, causing a material droplet of a first size and a second size to be ejected through the orifice. Alternately or in addition, the orifice area defines a first orifice having a first diameter and a second orifice having a second diameter different from the first diameter, whereby a signal causes a material droplet of a first size to be ejected through the first orifice and a material droplet of a second size to be ejected through the second orifice.
