  • Patent number: 10336056
    Abstract: A hybrid additive manufacturing method that allows for precise deposition of various photo curable resins without the use of a vat has been developed. This method utilizes thermoplastics for an exterior shell and structural support. This method of resin or epoxy deposition allows for stronger parts to be printed more rapidly through hybridization of two additive manufacturing methods. This hybrid nature greatly expands material compatibilities from strictly thermoplastics to thermoplastics and any photo curable resins. Furthermore, reinforcing materials or dopants can be incorporated into the part using the method and apparatus.

    Abstract: The systems and methods described herein include an approach to performing quality assessment for 3-D printed objects during the printing process, for collecting data regarding 3-D printed objects, and for capturing data to make a digital model of an object. This approach uses sensor data (e.g., digital imagery) to characterize printing progress or to detect 3-D printing defects that would otherwise result in printing incomplete objects, such as premature printing job termination, dry printing, over/under application, movement of the filament, and other defects. Sensor data capturing can also be used as part of a destructive scanning process to perform post-printing object assessment or to collect data on a real-world object to facilitate creation of a digital model. These systems and methods may leverage the discrete nature of a pixel provided through digital imagery to be assessed with limited computational resources in a non-recursive manner.

  • Patent number: 9361553
    Abstract: In various implementations, a computing device is configured to reconstruct a 3D model, such that reconstruction of the 3D model prevents the printing of long lines typically associated with cracking, bending, or decreased structural integrity of a 3D printed object based on the 3D model. In some implementations, a sliced 3D model is analyzed to determine that a structural characteristic of the 3D model is compatible for reconstruction. The 3D model is then reconstructed based on the determination that the 3D model is compatible. Other implementations analyze the 3D model to determine whether at least a portion of the 3D model shell has a seamless body. In this regard, the 3D model is reconstructed based on determining that the shell portion has a seamless body.

  • Patent number: 9321675
    Abstract: Provided herein are biocompatible scaffolds and methods of preparing such bioscaffolds. The methods provide a superior high surface area, interconnected nanomacroporous bioactive glass scaffold, by combining a sol-gel process and polymer sponge replication methods. The formation of a uniformly nanoporous and interconnected macroporous bioscaffold is demonstrated using a starting material comprising a 70 mol % SiO2—30 mol % CaO glass composition as an example. The bioscaffold includes a series of open, interconnected macropores with size from 300 to 600 ?m, as desired for tissue ingrowth and vascularization. At the same time, coexisting nanopores provide high-specific surface area (>150 m2/g), which is needed for enhancing the structure's degradation rate. These bioscaffolds hold promise for applications in hard tissue engineering.

  • Patent number: 9302338
    Abstract: A method for manufacturing parts and molds by: 1) slicing a three-dimensional CAD model of a part or mold; 2) planning a modeling path according to slicing data of the three-dimensional CAD model, whereby generating numerical control codes for modeling processing; and 3) performing fused deposition modeling of powders or wire material of metal, intermetallic compounds, ceramic and composite functional gradient materials by layer using a welding gun on a substrate layer via a numerical control gas shielded welding beam or laser beam according to a track specified by the numerical control code for each layer. A micro-roller or a micro-extrusion unit is installed at a contact area between melted and softened areas. The micro-roller or the micro-extrusion unit synchronously moves along with fused deposition area, which results in compressing and processing of the fused deposition area during the fused deposition modeling.

  • Patent number: 9079356
    Abstract: In the case of a method and an apparatus, three-dimensional objects (16) can be produced from a solidifiable material by the sequential discharging of discontinuous drops (15). To this end, the solidifiable material is plasticized in the fluid phase and is introduced into a material store (12) having at least one discharging unit (13) which can be clocked. From there, the material is discharged in a dropwise manner by means of a discharging unit (13) in the direction of an object carrier (14) for an object (16), wherein the object carrier (14) and an outlet opening can be moved at a relative spacing in relation to one another in space in order to influence the drop shape. The creation of the drops is supported by changing the relative spacing in an alternating manner in opposite directions during the discharging of the drops from the discharging unit (13) and during the application of the drops to the three-dimensional object (16) during the production of the object.

  • Patent number: 9067446
    Abstract: A printer detects inoperative inkjets during printing of three dimensional objects. The printer includes a substrate onto which a printhead ejects building and support material in a test pattern. An ultrasonic sensor scans the substrate on the unprinted side and measures thicknesses at a plurality of locations on the substrate. The thickness measurements are used to identify inoperative inkjets in the printhead and the printing of an object can be suspended to take remedial action with regard to the printhead before formation of the object is completed.
