  • Patent number: 12213908
    Abstract: Methods and apparatuses for manipulating the temperature of a surface are provided. Devices of the present disclosure may include a thermal adjustment apparatus, such as a controller in electrical communication with one or more thermoelectric materials, placed adjacent to the surface of skin. The device may generate a series of thermal pulses at the surface, for providing an enhanced thermal sensation for a user. The thermal pulses may be characterized by temperature reversibility, where each pulse includes an initial temperature adjustment, followed by a return temperature adjustment, over a short period of time (e.g., less than 120 seconds). The average rate of temperature change upon initiation and upon return may be between about 0.1° C./sec and about 10.0° C./sec. In some cases, the average rate of the initial temperature adjustment is greater in magnitude than the average rate of the return temperature adjustment.

  • Publication number: 20240083116
    Abstract: Methods provide for fabricating objects through additive manufacturing in a manner that compensates for deformations introduced during post-print processing, such as sintering. An initial model may be divided into a plurality of segments, the initial model defining geometry of an object. For each of the segments, modified geometry may be calculated, where the modified geometry compensates for a predicted deformation. Print parameters can then be updated to incorporate the modified geometry, where the print parameters define geometry of the printed object (e.g., configuration settings of the printer, a tool path, an object model). The object may then be printed based on the updated print parameters.

  • Patent number: 11554418
    Abstract: Assemblies fabricated by additive manufacturing include an object and a base plate providing support to the object during the manufacturing process. The geometry of the base plate is defined to optimize space and material constraints. During sintering, the base plate is reduced in area in a manner complementing the reduction in the footprint of the object, preserving the fidelity of the finished object.

  • Patent number: 11511347
    Abstract: Support substrates are used in certain additive fabrication processes to permit processing of an object. For additive fabrication processes with materials that are sintered into a final part, a multi-layer support substrate of interleaved support and interface layers is fabricated to support an object while reducing an impact of friction on shrinkage of the part during the sintering process.

  • Patent number: 11472116
    Abstract: Complexity of a geometry of a desired (i.e., target) three-dimensional (3D) object being produced by an additive manufacturing system, as well as atypical behavior of the processes employed by such a system, pose challenges for producing a final version of the desired 3D object with fidelity relative to the desired object. An example embodiment enables such challenges to be overcome as a function of feedback to enable the final version to be produced with fidelity. The feedback may be at least one value that is associated with at least one characteristic of a printed object following processing of the printed object. Such feedback may be obtained as part of a calibration process of the 3D printing system or as part of an operational process of the 3D printing system.

  • Patent number: 11420254
    Abstract: A 3D printer includes a build plate providing a surface on which an object is printed. Prior to printing, a sheet is fixed to the surface of the build plate. The sheet is composed of a material that adheres to a binder component of the feedstock used to print the object. During printing, the first layer of the printed object forms a bond with the sheet, which secures the location of the first layer and resists movement of the object during printing. Following printing and the object gaining sufficient rigidity, the object and sheet can be removed together from the printer. The sheet may then be peeled from the object, and the object can undergo debinding and/or sintering to create a finished object.

  • Patent number: 11413684
    Abstract: 3D-printed parts may include binding agents to be removed following an additive manufacturing process. A debinding process removes the binding agents by immersing the part in a solvent bath causing chemical dissolution of the binding agents. The time of exposure of the 3D-printed part to the solvent is determined based on the geometry of the part, wherein the geometry is applied to predict the diffusion of the solvent through the 3D-printed part. The 3D-printed part is then immersed in the solvent bath to remove the binding agent, and is removed from the solvent bath after the time of exposure.

  • Publication number: 20220250149
    Abstract: Embodiments described herein relate to methods and systems for controlling the packing behavior of powders for additive manufacturing applications. In some embodiments, a method for additive manufacturing includes adding a packing modifier to a base powder to form a build material. The build material may be spread to form a layer across a powder bed, and the build material may be selectively joined along a two-dimensional pattern associated with the layer. The steps of spreading a layer of build material and selectively joining the build material in the layer may be repeated to form a three-dimensional object. The packing modifier may be selected to enhance one or more powder packing and/or powder flow characteristics of the base powder to provide for improved uniformity of the additive manufacturing process, promote sintering, and/or to enhance the properties of the manufactured three-dimensional objects.

  • Publication number: 20220234104
    Abstract: A method of metal additive manufacturing, including forming a three-dimensional object as a successive series of layers. At least some of the successive layers is formed by depositing a layer of build material powder on a work surface, depositing a predetermined pattern of fugitive fluid and depositing a predetermined pattern of binder fluid, wherein the predetermined pattern of fugitive fluid improves at least one characteristic of the three-dimensional part.
