    Abstract: Devices, systems, and methods are directed to binder jetting for forming three-dimensional parts having controlled, macroscopically inhomogeneous material composition. In general, a binder may be delivered to each layer of a plurality of layers of a powder of inorganic particles. An active component may be introduced, in a spatially controlled distribution, to at least one of the plurality of layers such that the binder, the powder of inorganic particles, and the active component, in combination, form an object. The object may be thermally processed into a three-dimensional part having a gradient of one or more physicochemical properties of a material at least partially formed from thermally processing the inorganic particles and the active component of the object.

  • Publication number: 20210291274
    Abstract: A method for fabricating an infiltrated object of a desired shape having a high volume fraction of infiltrant using an additively manufactured preform. Using an additive manufacturing technique, the preform is formed with graded macro-porosity. When infiltrated, the void volume of the macro-porosity is filled with infiltrant Optionally, the void volume may be varied across the profile of the object to create a gradient of mechanical properties in the infiltrated object.

  • Publication number: 20210276083
    Abstract: Devices, systems, and methods are directed to the use of nanoparticles for improving strength fabrication of three-dimensional objects formed through layer-by-layer process in which an ink is delivery of a binder delivered onto successive layers of a powder of inorganic particles in a powder bed. More specifically, nanoparticles of inorganic material can may be introduced into one or more layers of the metal powder in the powder bed and thermally processed to facilitate sinter necking, in the powder bed, of the metal particles forming the three-dimensional object. Such sinter necking in the powder bed can may improve strength of the three-dimensional objects being fabricated and, also or instead, can may reduce the likelihood of defects associated with subsequent processing of the three-dimensional objects (e.g., slumping and shrinking in a final sintering stage and/or inadequate densification of the final part).

  • Publication number: 20210237160
    Abstract: 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.

  • Publication number: 20210237347
    Abstract: Systems, methods, components, and materials are disclosed for stereolithographic fabrication of three-dimensional, dense objects. A resin including at least one component of a binder system and dispersed particles can be exposed to an activation light source. The activation light source can cure the at least one component of the binder system to form a green object, which can include the at least one component of the binder system and the particles. A dense object can be formed from the green object by removing the at least one component of the binder system in an extraction process and thermally processing particles to coalesce into the dense object.

  • Publication number: 20210220914
    Abstract: Disclosed is a method and material system for fabricating metal infiltrated objects having a high volume fraction of infiltrant relative to the infiltrated preform. In an embodiment method, a composite is formed into the shape of a desired object, the composite including a skeletal phase and a fugitive phase. The fugitive phase is then removed to create a self-supporting porous skeletal structure. The porous skeletal structure is then infiltrated with the infiltrant to achieve a densified object.

  • Publication number: 20210114110
    Abstract: A method of maintaining part geometry fidelity during infiltration of a metallic preform. The preform and an infiltration barrier are formed, either independently or together during an additive manufacturing process. The infiltration barrier prevents infiltrant from bleeding out from the preform where it is present, thus protecting fine geometries that would otherwise be filled with infiltrant.

  • Patent number: 10639717
    Abstract: Devices, systems, and methods are directed to applying magnetohydrodynamic forces to liquid metal to eject liquid metal along a controlled pattern, such as a controlled three-dimensional pattern as part of additive manufacturing of an object. Porosity of one or more predetermined portions of objects fabricated from an accumulation of liquid metal droplets ejected using magnetohydrodynamic force can be controlled to form interfaces between support structures and parts within the object. Higher porosity along the interfaces, as compared to porosity along the support structures and the parts, can be useful for facilitating separation of the parts from the support structures.

  • Patent number: 10456833
    Abstract: A variety of additive manufacturing techniques can be adapted to fabricate a substantially net shape object from a computerized model using materials that can be debound and sintered into a fully dense metallic part or the like. However, during sintering, the net shape will shrink as binder escapes and the base material fuses into a dense final part. If the foundation beneath the object does not shrink in a corresponding fashion, the resulting stresses throughout the object can lead to fracturing, warping or other physical damage to the object resulting in a failed fabrication. To address this issue, a variety of techniques are disclosed for substrates and build plates that contract in a manner complementary to the object during debinding and sintering.

  • Publication number: 20190240730
    Abstract: A three-dimensional printer includes a vessel containing a liquid in which a printed object can debind during fabrication. More generally, the vessel may contain any liquid medium selected to control or modify properties of a printed object during fabrication. For example, the liquid may also or instead impose a controlled thermal environment for the printed object, apply finishing materials to an exterior surface of the object, provide a component or catalyst for a reaction, or otherwise treat the printed object or control ambient conditions during printing.

  • Patent number: 10350682
    Abstract: Support structures are used in certain additive fabrication processes to permit fabrication of a greater range of object geometries. For additive fabrication processes with materials that are subsequently sintered into a final part, an interface layer is fabricated between the object and support in order to inhibit bonding between adjacent surfaces of the support structure and the object during sintering. Interface layers suitable for manufacture with an additive manufacturing system may resist the formation of bonds between a support structure and an object during subsequent sintering processes.
