Patent number: 12121968Abstract: A method for binder jetting a three-dimensional (3D) object includes receiving a geometry of the object to be printed and generating instructions for printing the object. Generating the instructions includes slicing the geometry of the object into a series of cross-sectional shapes corresponding to where a binder fluid will be deposited onto a powder bed to form the object, and including a plurality of negatively printed features within at least some of the series of cross-sectional shapes, wherein an amount of binder fluid to be deposited in the negatively printed features is less than an amount of binder fluid to be deposited in a remainder of the cross-sectional shape. The amount of binder fluid to be deposited in the negatively printed features and a size of the negatively printed features is configured to allow gas to escape from the powder bed.Type: GrantFiled: January 18, 2021Date of Patent: October 22, 2024Assignee: Desktop Metal, Inc.Inventors: Alexander C. Barbati, George Steven Hudelson, Christopher Benjamin Renner, Michael Andrew Gibson

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

Publication number: 20180236545Abstract: Devices, systems, and methods are directed to the use of nanoparticles for improving fabrication of three-dimensional objects formed through layer-by-layer delivery of an ink onto a powder of metal particles in a powder bed. More specifically, the ink may include a colloid of nanoparticles of an inorganic material (e.g., a metal) in a carrier, and the colloid may be destabilized along one or more sections of at least one layer. Destabilization of the colloid may aggregate the nanoparticles along at least one layer to facilitate, for example, formation of an interface layer useful for separating the three-dimensional objects from associated support structures. Further, or instead, the aggregated nanoparticles may be useful for hardening a given layer to facilitate uniform distribution of a subsequent layer on top of the given layer. Thus, more generally, aggregation of the nanoparticles along the powder be may be useful for improving quality of the three-dimensional objects being fabricated.Type: ApplicationFiled: February 21, 2018Publication date: August 23, 2018Inventors: Anna Marie Trump, Michael Andrew Gibson, Christopher Benjamin Renner
