  • Patent number: 10435535
    Abstract: A material system and method for bonding refractory powders in a three dimensional printer. A first particulate component including a refractory material is mixed with a first reactive component to form a particulate mixture. A flat layer of the particulate mixture is dispensed onto a build surface. A liquid binder, which may include a furan monomer and a surfactant, is dispensed by an ink-jet printhead onto the particulate mixture. The particulate mixture may contain a furan-soluble polymer that imposes a capillary attraction for the liquid binder, keeping it situated in the immediate vicinity of where the binder is dispensed. Additionally it provides a sufficient catalytic power to co-polymerize with the furan monomer and form a solid structure. This enables a 3D printer to build strong, accurate parts with high packing density, and to reuse the feed material many times in the printer.

  • Patent number: 9827715
    Abstract: A three-dimensional formation apparatus includes a head unit which can discharge liquid in a first direction and a control unit which controls the head unit. The control unit forms a cross section object by discharging the liquid containing a second quantity which is smaller than the first quantity to a changed portion where an outline of the cross section object is simultaneously changed in the second direction and the third direction, in the first cross section object formation process, and executes a filling process of discharging the liquid containing a third quantity which exceeds the first quantity when the third quantity is added to the second quantity to a portion to which the liquid containing the second quantity is discharged, after the first cross section object formation process is executed and before the second cross section object formation process is executed.

  • Patent number: 9802362
    Abstract: A three-dimensional formation apparatus includes a head-unit which can discharge liquid in a first-direction and a control-unit which controls the head-unit. The control-unit forms a hollow on a changed portion where an outline of a cross section object is simultaneously changed in a second-direction and a third-direction towards the inside from the outline of the cross section object in the second-direction or the third-direction, in a first cross section object formation process and executes a filling process of discharging the liquid containing a second quantity which is larger than a first quantity to the hollow so as to come in contact with the cross section object formed in the first cross section object formation process, to fill at least a part of the hollow with the liquid, after the first cross section object formation process is executed and before the second cross section object formation process is executed.

  • Patent number: 9750801
    Abstract: Replicating recombinant adenovirus vectors derived from human adenovirus serotype 26 or human adenovirus serotype 35 are described. The replicating recombinant adenovirus vectors have attenuated replicative capacity as compared to that of the corresponding wild-type adenovirus. They can be used for stable expression of heterologous genes in vivo. Also described are compositions and methods of using these recombinant adenovirus vectors to induce an immune response in a subject, and vaccinate a subject against an immunogenic human immunodeficiency virus (HIV) infection.

  • Patent number: 9688020
    Abstract: Embodiments of the present invention are directed to a system and method for reusing surplus material generated by an Additive Manufacturing system in the process of manufacturing a 3-dimensional (3D) object. Surplus material removed from deposited layers and purged material used for printing head maintenance are transferred to back to the printing system to be deposited within subsequent layers. The reusable material may be deposited within the boundaries of a cross section of the 3-dimensional object to become part of 3D object or outside the boundaries of a cross section of the 3-dimensional object as part of the support construction, which is removed from the finished product. According to embodiments of the invention, a portion of the waste material for disposal may be deposited and cured layer by layer to form a waste block, concurrently with printing the layers of the 3D dimensional object. The fully cured waste block may be then disposed of in a safe manner.

  • Patent number: 9662189
    Abstract: A method and apparatus for making a denture base disc that is used subsequently to form a removable denture. A vessel with an elastomeric lining is used to form the denture base disc so that the compression of the elastomeric material is approximately equivalent to the shrinkage of the denture base disc material during its polymerization. The vessel and elastomeric lining contained therein work cooperatively to cause the denture base disc to cure in a homogenous manner with consistent pressure on all sides so that residual stresses in the finished disc are minimized.

    Abstract: A mobile cart for a three-dimensional object printing system includes a mechanism that enables vertical movement of the platen with reference to ejector heads in the system. The mobile cart includes a pair of links at each end of a cart that pivotally connect a member positioned between the cart and the platen to the cart and the platen. An actuator is configured to laterally move the member bi-directionally and along an axis that is orthogonal to the member. This movement of the member pivots the links to raise and lower the platen depending on the direction in which the member is urged by the actuator.
