Abstract
A system for fabricating a three-dimensional article includes a fluid supply with binding agent, a printhead, a powder dispenser, and a controller. The fluid supply is for containing a binding agent. The controller is configured to (a) operate the fluid supply and/or the printhead to elevate a temperature of the binding agent to above 25 degrees Celsius, (b) operate the dispenser to dispose a layer of the powder at a build plane, (c) scan and operate the printhead to selectively jet the binding agent onto the layer of powder to bind a layer of the three-dimensional article, and (d) repeat operating the dispenser and scanning and operating the printhead to complete fabrication of the article. Jetting or not jetting the binding agent includes individually operating drop ejectors of the printhead using a voltage waveform. The waveform can include one or more of a non-ejecting pulse and an ejecting pulse.
