  • Patent number: 10696036
    Abstract: A three-dimensional fabricating apparatus includes a fabrication chamber, a flattening member, a surplus powder chamber, and an impact applicator. The fabrication chamber stacks powder in layers and a layered fabrication object in which the powder is bonded together. The flattening member relatively moves with respect to the fabrication chamber to fill the fabrication chamber with the powder. The surplus powder chamber is disposed outside the fabrication chamber, to receive a surplus of the powder having not been filled in the fabrication chamber. The impact applicator is movable with the flattening member to contact and impact on the surplus powder chamber.

  • Patent number: 10589442
    Abstract: A method for processing printing information of a powder-bed type 3D printer is disclosed. The method comprises following steps of: generating a color image and an adhesive image for each printing slice in accordance with a 3D file; adjusting adhesive information of the adhesive image based on color information of the color image; and, generating a final printing image based on the color image and the adjusted adhesive image. The method prevents the 3D printing from jetting adhesive that may overlap with jetted colored ink by using the final printing image, so as to avoid the jetted color-ink being diluted by the adhesive, and powders being moist because of the overlap of the colored ink and the adhesive.

  • Patent number: 10522324
    Abstract: A method for creating a low-cost specimen used for training users in lift out techniques is prepared using additive manufacturing. This replaces the more expensive and time-intensive subtractive manufacturing methods traditionally used that operate by milling or ablation with charged particle focused ion beam (FIB) instruments or lasers. The method comprises building up a sample from a substrate surface using additive manufacturing, building up trench walls within the sample that frame a trench using additive manufacturing, and building up a specimen between the trench walls using additive manufacturing. In a preferred form, the specimen has a shape taken from the group consisting of a lamella, a rectangular cuboid, a triangular prism, and a regular prism. Tabs and other support structures may be eliminated using subtractive milling or chemical dissolving methods to create a freestanding specimen separate from the trench.

    Abstract: A method for compensating for inoperative ejectors in a three-dimensional object printer has been developed. A printer detects an inoperative ejector in a printhead. The printer identifies functional ejectors that print at locations adjacent to locations where the inoperative ejector fails to print a drop. The printer modifies firing signals for the functional ejectors so those ejectors print drops having an increased drop volume at the locations adjacent to locations where the inoperative ejector fails to print a drop. The printer prints a first layer of material drops using the modified firing signals. The printer advances the printhead in the cross-process direction between layers so that locations where the inoperative ejector fails do print a drop do not coincide between layers.

  • Publication number: 20140349081
    Abstract: A co-injected molded multi-layer article has inner and outer layers, an interior layer contained within the inner and outer layers and a surface portion to which a closure or other component may be heat-sealed. The article is molded by co-injecting the inner, outer and interior layer materials into a mold cavity of a mold. The interior layer material is caused to flow along a steam line offset from the zero velocity gradient of the combined material flow and biased toward a material flow for forming an outer wall of the multi-layer article. The resultant molded multi-layer article contains an interior layer located in a heat sealable region that avoids a breach or failure during a heat seal operation to seal an opening of the molded article.

  • Publication number: 20140272222
    Abstract: Disclosed herein are methods and systems for the preparation of a co-injection molded multilayer plastic article. Some methods include co-extruding a combined polymeric stream having an interior core stream encased by an inner stream and an outer stream. One or more pulses in a thickness of the interior core stream create portions of an edge of the outer flow stream flowing along different streamlines. A first portion of an outer edge of the interior core stream flows beyond a second portion of the outer edge thereby forming one or more cohesion members that physically interlock the interior layer with the inner layer, with the outer layer or with both. Some embodiments reduce or eliminate a need for addition of an adhesive in the composite stream to prevent delamination of layers of the resulting multilayer plastic article. In some embodiments, cohesion members may be employed to produce a desired cosmetic effect in a resulting article.
