  • Patent number: 11353847
    Abstract: Set differences between an as-designed and an as-manufactured model are computed. Discrepancies between the as-designed model and the as-manufactured model are determined based under-deposition and over-deposition features of the set differences. Based on the discrepancies, an input to a manufacturing instrument is changed to reduce topological differences between the as-manufactured model and the as-designed model.

  • Patent number: 11300941
    Abstract: An automated manufacturing system includes two simultaneous and independently operating toolheads accessing any location within the same work volume, with the exception of locations in proximity to each other. The system includes a bed platform connected with X and Y linear axes. A ? rotational axis rotates the bed and its linear axes as a unit. A first toolhead has a fixed position relative to the ? axis, and a second toolhead is coupled with a linear R axis parallel to the bed. The bed X and Y axes move the bed relative to the first toolhead, enabling the first toolhead to reach any portion of the bed. The R linear axis and ? rotational axis allow the second toolhead to move almost anywhere in a circular area that is always centered near the first toolhead. The system's kinematics ensure that it is impossible for the toolheads to collide.

    Abstract: A system is used for additively manufacturing propellant elements, such as for rocket motors, includes partially curing a propellant mixture before extruding or otherwise dispensing the material, such that the extruded propellant material is deposited on the element in a partially-cured state. The curing process for the partially-cured extruded material may be completed shortly after the material is put into place, for example by the material being heated at or above its cure temperature, such that it finishes curing before it fully cools. The propellant material may be prepared by first mixing together, a fuel, an oxidizer, and a binder, such as in an acoustic mixer. After that mixing a curative may be added to the mixture. The propellant mixture may then be directed to an extruder (or other dispenser), in which the mixture is heated to or above a cure temperature prior to the deposition, and then deposited.

  • Patent number: 10882250
    Abstract: An additive manufacturing system enables continual production of three-dimensional objects without operator intervention. The system is configured to form an object on a planar member, rotate the planar member 180° to enable gravity to move the object from the planar member to an object transport, which carries the object to a receptacle for storage and later processing. The opposite side of the planar member is then available for manufacture of another object and the planar member is again rotated following manufacture of the object so it can be removed and carried to the receptacle. The alternating formation of objects on opposite sides of the planar member continues until a predetermined number of objects has been made. The planar member can include one or more heaters to heat the surface on which an object is formed to facilitate release of the object once the planar member has been rotated.
