20150352789 | THREE-DIMENSIONAL PRINTER WITH INTEGRATED COLORING SYSTEM - A three-dimensional printer effects color changes in an extrudate using a color-application unit applying a colorant to the interior of a filament before it is melted within an extruder. Specifically, the color-application unit may receive a filament (or portions thereof) having an exposed interior surface, where color applicators are actuated to apply one or more colors to the interior surface of the filament in order to modify the extruded color. The filament may then be coupled, collapsed, or otherwise closed about the interior surface, e.g., by a mechanical coupler, to substantially enclose the interior surface of the filament, which is then fed to the extruder for fabricating a colored object in a three-dimensional fabrication process. By enclosing the colored surface within the filament before melting for extrusion, transition effects of a color change can be mitigated and transition time for a substantially complete change in color can be significantly reduced. | 12-10-2015 |
20160016360 | THREE DIMENSIONAL (3D) PRINTER AND FILAMENT MATERIAL PROVIDING SCANNING PROTECTION FOR 3D PRINTED OBJECTS - A printer adapted for printing three dimensional (3D) objects that are difficult to copy by use of a 3D scanner and 3D printer. The printer includes a print head with an extrusion nozzle with a heated portion and a print bed with a surface for receiving material extruded from the extrusion nozzle. The printer includes a print material supply spool loaded with an anti-scanning filament. The print head is adapted for drawing the anti-scanning filament into the heated portion for heating prior to extrusion from the extrusion nozzle to form a 3D object. Further, the 3D object includes one or more scan protected exterior surfaces on at least one element of the 3D object. The scan protected exterior surfaces are either light absorbing surfaces or reflect light in one or more unconventional directions. The anti-scanning filament may be a plastic mixed with an anti-scanning additive such as a retroreflective material. | 01-21-2016 |
20160031155 | Method and Apparatus for Additive Mechanical Growth of Tubular Structures - A method and apparatus is disclosed for additive manufacturing and three-dimensional printing, and specifically for extruding tubular objects. A print head extrudes a curable material into a tubular object, while simultaneously curing the tubular object and utilizing the interior of the cured portion of the tubular object for stabilizing and propelling the print head. | 02-04-2016 |
20160046803 | 3D PRINTING WITH PHT/PHA BASED MATERIALS AND POLYMERIZABLE MONOMERS - This application describes methods of forming an object. The methods described include forming a mixture with i) one or more primary diamines, ii) one or more polymerizable monomers, iii) a formaldehyde-type reagent, and iv) a polymerization initiator; forming a gel by heating the mixture to a temperature of at least 50° C.; and curing the one or more polymerizable monomers by activating the polymerization initiator. The one or more primary diamines may include one or more amine functional oligomers and/or primary aromatic diamine small molecules. The one or more polymerizable monomers may include styrenics, acrylates, methacrylates, vinyl esters, unsaturated polyesters, and derivatives thereof. The gel is a polyhemiaminal (PHA), a polyhexahydrotriazine (PHT), and/or a polyoctatriazacane (POTA) polymer, and curing of the gel forms an interpenetrating network of the PHA/PHT/POTA and the polymer formed from the polymerizable monomers. | 02-18-2016 |
20160096329 | 3D TOOLING MACHINE - Some embodiment includes a 3D tooling machine. The 3D tooling machine can include: a base station; slider blocks; rods that are adapted to support the top cap, run through the slider blocks and plug into the base station; slider arms with rounded ends that are adapted to magnetically attach to the slider blocks and magnetically attach to a tool head; and a controller configured to control movement of the slider blocks along the rods via one or more motors or actuators. | 04-07-2016 |
20160107378 | THREE-DIMENSIONAL PRINTER HAVING AN EXPANDABLE ENVELOPE - One embodiment of the present invention provides a method of three-dimensional printing. The method includes a three-dimensional printer printing a first layer of an object onto a surface that is not part of the three-dimensional printer, wherein the first layer is printed while a printing platform of the three dimensional printer is in a first position. The printer is autonomously repositioned in a second position elevated above the first position by being supported either on the three-dimensional object itself or on a scaffold printed separate from the object. The printer prints a second layer of the three-dimensional object onto the first layer of the three-dimensional object while the printing platform is in the second position. The printer may have a plurality of legs for controllably repositioning the printing platform. | 04-21-2016 |
20160136883 | Techniques for Automatically Placing Escape Holes during Three-Dimensional Printing - In one embodiment of the present invention, an escape hole generator creates escapes holes designed to facilitate removal of support and/or unprinted material generated inside enclosed hollows of three-dimensional (3D) digital models during 3D printing. In operation, the escape hole generator identifies a hollow included in the three-dimensional model and then selects optimized locations for escape holes. Notably, the escape hole generator selects the locations to optimize placement heuristics, such as favoring locations closer to the bottom of the 3D model, while satisfying escape hole constraints (e.g., hole size and spacing requirements). The escape hole generator then perforates the hollow at the selected locations with geometries that provide channels from the outer surface of the hollow to the outer surface of the hollow. Advantageously, automating escape hole generation enables efficient creation of hollowed 3D models that reduce 3D printing time and material usage compared to solid 3D model counterparts. | 05-19-2016 |
20160144542 | IN-MOLD DECORATIVE APPLIQUE WITH TEXTURED SURFACE - A manufacturing method for a plastic-molded automotive interior trim component produces a curvilinear finished surface with a relatively flat portion and a relatively curved portion. A decorative film subcomponent is molded with a substantially smooth outer surface that is pigmented with a desired color of the finished surface. The decorative film subcomponent is placed into a mold having a film-receiving surface with a three-dimensional texture at both the relatively flat portion and the relatively curved portion. A structural backing member is in-mold laminated with the decorative film subcomponent by injecting molten plastic material against the inner surface of the decorative film subcomponent in the mold, wherein pressure of the molten plastic material expands the decorative film subcomponent to form an embossed pattern which is substantially uniform and undistorted covering at least part of the relatively flat portion and at least part of the relatively curved portion. | 05-26-2016 |
20160144574 | METHOD AND SYSTEM FOR ADAPTING A 3D PRINTING MODEL - A method for adapting a 3D printing model includes calculating a layer representation model on the basis of a 3D object model of an object; determining a plurality of overhang regions in the layer representation model where the boundary edges of first layers extend over the boundary edges of second layers, the first layers being directly adjacent and subsequent to the second layers when going into the build-up direction of the layer representation model; determining a local overhang angle in each of the plurality of overhang regions; adapting the layer representation model by re-defining the boundary edges of layers in the overhang regions so that the local overhang angle remains below a predetermined overhang threshold angle; and outputting the adapted layer representation model as 3D printing model to the 3D printing apparatus. | 05-26-2016 |
