摘要： Electron beam powder bed fusion may be performed using waste powder from laser beam powder bed fusion by pre-heating a build chamber using stepped increases of electron beam current. To perform the pre-heating without smoking the powder, a plurality of predetermined interim temperatures, ranging from an ambient, resting temperature of the build chamber to a predetermined preheated temperature, are determined. A build plate within the build chamber is exposed to a plurality of streams of electrons, one at a time, while the build plate is surrounded by the waste powder. Each stream of electrons has a progressively increasing current, with the current being increased each time an actual temperature of the build chamber reaches or exceeds the next predetermined interim temperature. The actual temperature of the build chamber is monitored during the pre-heating, to compare the actual temperature of the build chamber to the plurality of predetermined interim temperatures.

摘要： This disclosure describes various methods and apparatus for characterizing an additive manufacturing process. A method for characterizing the additive manufacturing process can include generating scans of an energy source across a build plane; measuring an amount of energy radiated from the build plane during each of the scans using an optical sensor; determining an area of the build plane traversed during the scans; determining a thermal energy density for the area of the build plane traversed by the scans based upon the amount of energy radiated and the area of the build plane traversed by the scans; mapping the thermal energy density to one or more location of the build plane; determining that the thermal energy density is characterized by a density outside a range of density values; and thereafter, adjusting subsequent scans of the energy source across or proximate the one or more locations of the build plane.

摘要： A printer fabricates an object from a computerized model using a fused filament fabrication process. A former extending from a nozzle of the printer supplements a layer fusion process by applying a normal force on new material as it is deposited to form the object. The former may use a variety of techniques such as heat and rolling to improve physical bonding between layers.

摘要： A method of synthesis of two-dimensional (2D) nanoparticles comprises combining a first nanoparticle precursor and a second nanoparticle precursor in one or more solvents to form a solution, followed by heating the solution to a first temperature for a first time period, then subsequently heating the solution to a second temperature for a second time period, wherein the second temperature is higher than the first temperature, to effect the conversion of the nanoparticle precursors into 2D nanoparticles. In one embodiment, the first nanoparticle precursor is a metal-amine complex and the second nanoparticle precursor is a slow-releasing chalcogen source.

摘要： Embodiments set forth in this application relate to systems and methods by which parts produced by additive manufacturing can be reliably assessed for conformity to a known master model which has quality conforming to the desired specifications. These systems and methods involve recording a thermal history of the manufacturing process of each part. The recorded thermal history is then compared to the previously-recorded thermal history of the master model. Significant deviations in thermal history are indicative of irregularities in the manufacturing build, and the part quality may then be assessed in view of those irregularities.

摘要： A high-precision three-dimensional laminated and shaped object is shaped based on a captured image. A three-dimensional laminating and shaping apparatus includes a material ejector that ejects a material of a three-dimensional laminated and shaped object onto a shaping table, a light beam irradiator that irradiates the ejected material with a light beam, an image capturer that captures a molten pool formed by irradiating the ejected material with the light beam, a scanning direction determiner that determines a scanning direction of the light beam with respect to a shaped object based on a change in a position of the shaping table, a detector that detects the molten pool based on an image captured by the image capturer and the scanning direction, and a shaping controller that controls at least one of an output of the light beam and a scanning speed of the light beam based on the detected molten pool.
