    Abstract: A consumable scaffold and technique for supporting an object while it is being manufactured is disclosed. The consumable scaffold comprises a base sheet and an array of pillars that are cantilevered from one side of the sheet. The consumable scaffold resembles a bed of nails. Each pillar in the array of pillars is trimmed to a desired length and the object is manufactured by fusing thermoplastic filaments to the tips of the pillars.

  • Patent number: 10569474
    Abstract: A technique for additive manufacturing that avoids the necessity of having a build plate. The illustrative embodiment comprises two anchor plates from which a structure is constructed that forms at least the initial support for the object to be manufactured. The envelope of the structure can be a cylinder, a box, an n-sided prism, a hyperboloid of one sheet, a cone, the frustum of a cone, a pyramid, and the frustum of a pyramid.

  • Patent number: 10556382
    Abstract: The present invention relates to a system and a method for optimizing printing parameters, such as slicing parameters and tool path instructions, for additive manufacturing. The present invention comprises a property analysis module that predicts and analyses properties of a filament object model, representing a constructed 3D object. The filament object model is generated based on the tool path instructions and user specified object properties. Analysis includes comparing the predicted filament object model properties with the user specified property requirements; and further modifying the printing parameters in order to meet the user specified property requirements.

  • Publication number: 20200016883
    Abstract: The present invention provides a system and a method for real time monitoring and identifying defects occurring in a three dimensional object build via an additive manufacturing process. Further, the present invention provides in-situ correction of such defects by a plurality of functional tool heads possessing freedom of motion in arbitrary planes and approach, where the functional tool heads are automatically and independently controlled based on a feedback analysis from the printing process, implementing analyzing techniques. Furthermore, the present invention provides a mechanism for analyzing defected data collected from detection devices and correcting tool path instructions and object model in-situ during construction of a 3D object. A build report is also generated that displays, in 3D space, the structural geometry and inherent properties of a final build object along with the features of corrected and uncorrected defects.

  • Publication number: 20190315115
    Abstract: An apparatus performing as a base for printing 3D objects using high temperature thermoplastics employing additive manufacturing methods is provided. The apparatus comprises a heated build platform, a thin removable plate secured on top of the build platform, a high temperature polymer coating applied over the removable plate, and surface treatment of high temperature polymer coating to maintain adhesion between 3D object and printing surface. Also, the removable plate has low coefficient of thermal expansion compared to build platform below it, for avoiding bowing of the plate as it is heated due to heated build platform, hence providing flat printing surface. The thin removable plate allows 3D objects to pop off the plate upon cooling, without damaging the polymer coating, the plate, or the object. It also allows for continuous operation of printing, while the plate is released for cooling, a new plate is installed for printing.

  • Patent number: 10364341
    Abstract: An apparatus and method for printing an object via additive manufacturing is disclosed. In accordance with an illustrative embodiment, one or more inks are prepared, including a thermo-polymer ink, a nano-filler ink, and a thermo-polymer/nano-filler ink. In some embodiments, an object is printed by depositing alternating layers of thermo-polymer ink and nano-filler ink and exposing the layers to microwave radiation. In some other embodiments, an object is printed by depositing alternating layers of thermo-polymer/nano-filler ink and nano-filler ink and exposing the layers to microwave radiation. In some additional embodiments, an object is printed by depositing successive layers of thermo-polymer/nano-filler ink and exposing them to microwave radiation.
