Patent number: 11858210Abstract: Devices, systems, and methods are directed to the use of vapor phase change in binder jetting processes for forming three-dimensional objects. In general, a vapor of a first fluid may be directed to a layer of a powder spread across a build volume. The vapor may condense to reduce mobility of the particles of the powder of the layer. For example, the condensing vapor may reduce the likelihood of particle ejection from the layer and, thus, may reduce the likelihood of clogging or otherwise degrading a printhead used to jet a second fluid (e.g., a binder) to the layer. Further, or instead, the condensing vapor may increase the density of the powder in the layer which, when repeated over a plurality of layers forming a three-dimensional object, may reduce the likelihood of slumping of the part during sintering.Type: GrantFiled: September 29, 2022Date of Patent: January 2, 2024Assignee: Desktop Metal, Inc.Inventors: Emanuel Michael Sachs, George Hudelson, Paul A. Hoisington, Christopher Benjamin Renner, Keith Roy Vaillancourt, Edward Russell Moynihan
