摘要： The devices, systems, and methods of the present disclosure are directed to powder spreading and binder distribution techniques for consistent and rapid layer-by-layer fabrication of three-dimensional objects formed through binder jetting. For example, a powder may be spread to form a layer along a volume defined by a powder box, a binder may be deposited along the layer to form a layer of a three-dimensional object, and the direction of spreading the layer and depositing the binder may be in a first direction and in a second direction, different from the first direction, thus facilitating rapid formation of the three-dimensional object with each passage of the print carriage over the volume. Powder delivery, powder spreading, thermal energy delivery, and combinations thereof, may facilitate consistently achieving quality standards as the rate of fabrication of the three-dimensional object is increased.

摘要： In an example implementation, a method of operating a sintering furnace includes receiving information about a green object load to be sintered in a sintering furnace, determining a sintering profile based on the information, and performing a sintering process according to the sintering profile. During the sintering process, a sensor reading that indicates a degree of densification of a green object in the load is accessed from a densification sensor. The method includes initiating a cool down phase of the sintering process if the sensor reading has reached a target sensor reading.

摘要： Certain aspects of the technology disclosed herein include an apparatus and method for forming nanoparticles. The method includes a mechanical milling process induced by aerodynamic, centrifugal, and centripetal forces and further augmented by ultrasound, magnetic pulse, and high voltage impact. A nanoparticle mill having an atmospheric and luminance controlled environment can form precisely calibrated nanoparticles. A nanoparticle mill can include first aerodynamic vane configured to rotate around a central axis of the nanoparticle mill in a first direction, and a second aerodynamic vane configured to rotate around the central axis in a second direction. An aerodynamic shape of an aerodynamic vane can be configured to cause particles within the nanoparticle mill to flow around the aerodynamic vane. The nanoparticle mill can include a primary product line, a nanoparticle sampling line, a particle programming array, a solidifying chamber, or any combination thereof.

摘要： Described are cementitious reagent materials produced from globally abundant inorganic feedstocks. Also described are methods for the manufacture of such cementitious reagent materials and forming the reagent materials as microspheroidal glassy particles. Also described are apparatuses, systems and methods for the thermochemical production of glassy cementitious reagents with spheroidal morphology. The apparatuses, systems and methods makes use of an in-flight melting/quenching technology such that solid particles are flown in suspension, melted in suspension, and then quenched in suspension. The cementitious reagents can be used in concrete to substantially reduce the CO2 emission associated with cement production.

摘要： An implant is produced by fabricating first and second layers. The first layer of repeated and truncated building units is fused together to define pores. The second layer of repeated and truncated building units are fused together to define pores and fused onto the first layer of truncated building units. The first and the second layers form at least part of a porous portion of the implant. The formed porous portion is attached onto a base portion of an implant. The truncated building units of each of the first and the second layers are in the form of spatially overlapping three-dimensional shapes.
