    Abstract: A powder filtering mechanism includes a connecting part, a main body, a duct, a suction device and a bracket. The connecting part is in communication with a powder inlet. Moreover, plural filters are disposed within an accommodation space of the main body. The suction device is in communication with the main body. The bracket supports a micro-particle adsorption structure. During operation of the suction device, flying dust of excess construction powder is inhaled into the powder inlet, and a portion of the flying dust is transferred to the accommodation space. After the portion of the flying dust is filtered by the plural filters in multiple filtering steps, micro-particles of flying dust passing through the plural filters are transferred to the micro-particle adsorption structure so as to be adsorbed by the micro-particle adsorption structure.

  • Patent number: 9878492
    Abstract: The problem to be solved is, when printing a 3D object by using a 3D printer of fused-deposition-modeling type or another type, to enable printing it even when the filament is not supported from underneath by avoiding filament drop by generating force to push the extruded filament to the neighbor filament, and to enable arraying the filaments to a horizontal direction. To avoid filament drop, force that pushes the newly extruded filament to the neighboring filament is generated, and filament drop is avoided. To do so, compression or extension power is generated by controlling the filament cross section by controlling the filament cross-section (i.e., the extrusion amount) and stiffness of the filament is controlled by controlling the temperature or light.

  • Publication number: 20150079213
    Abstract: A rapid prototyping apparatus includes a construction platform, a movable platform, and a page-width array printing module. The construction platform includes a construction chamber. The movable platform and the construction platform are movable relative to each other. The page-width array printing module includes plural inkjet head structures. The printing platform and the movable platform are synchronously moved along a single direction in a reciprocating motion. The plural inkjet head structures are collaboratively defined as at least one page-width array printing unit. The plural inkjet head structures include respective inkjet chips. The inkjet chips are arranged in plural rows and in a staggered form, so that a printing width of the inkjet chips is larger than or equal to a width of a printed pattern. Moreover, at least one monochromatic print liquid is introduced into the construction chamber from the plural inkjet head structures.

  • Publication number: 20150078712
    Abstract: A method of manufacturing an optical interconnect includes 3D printing a plurality of non-intersecting and spaced apart optical waveguides from a material that guides electromagnetic waves in the optical spectrum after being cross-linked or polymerized in a region activated by the 3D printing. At least some of the optical waveguides change direction at least once by about 90°. The method further includes encasing at least each end of the optical waveguides with a material having a lower index of refraction than the material from which the optical waveguides are formed by 3D printing, to secure the optical waveguides. A corresponding 3D printing apparatus is also described.

  • Publication number: 20150076732
    Abstract: An extended structure additive manufacturing device and method are provided. The device includes a movable material bonding component and a movement mechanism which enable the device to create parts outside the conventional additive manufacturing device print volumes defined by the device and its print-head. Methods of making parts involve creating a portion of a part and moving the extended structure additive manufacturing device relative to the part and printing a second portion of the part. Parts incapable of being formed using a conventional additive manufacturing device may be made using the extended structure additive manufacturing device and/or methods disclosed herein.

  • Publication number: 20150079214
    Abstract: A page-width printing platform comprises a plurality of inkjet head structures collaboratively defined as at least one page-width array printing unit. The inkjet head structures comprise respective inkjet chips disposed on the printing platform and arranged in plural rows and in a staggered form, so that a printing width of the inkjet chips is larger than or equal to a width of a printed pattern. Each of the inkjet chips comprises at least one liquid supply slot, wherein a plurality of liquid ejectors are located at one or two sides of the liquid supply slot along a long axis of the liquid supply slot. At least one monochromatic print liquid is introduced into the construction chamber from the plural inkjet head structures and printed on a construction material within the construction chamber, so that a rapid prototyping width-page printing operation is performed.

  • Publication number: 20150079217
    Abstract: A device for printing simultaneously three dimensional objects includes a support surface for supporting the object to be printed and a carriage arranged over the support surface. The carriage is movable along two axes of a Cartesian coordinate system parallel to the support surface the distance between the carriage and the support surface is adjustable. A number of printing heads are arranged at the carriage. The printing heads are positioned at a regular first pitch distance along the first axis of the Cartesian coordinate system and at a regular second pitch distance along the second axis of the Cartesian coordinate system.

  • Patent number: 8974213
    Abstract: The current document discloses an apparatus and method that support manufacture of large 3D hollow objects or shells with thin walls including curved surfaces with high and low curvature change ratio and alleviate or significantly reduce the need for support structures. Further to this, introduction of support structures becomes a function of the curved surface curvature change ratio.

  • Patent number: 8974219
    Abstract: A modular tool for imparting profile characteristics into fluent cementitious material. The tool has an elongated base forming a permanently fixed blade, and at least one handle. The blade is configured to act as a dovetail to which any of several modular blades may frictionally fit in removable fashion. The fixed blade forms a deflector disposed to deflect removed cementitious material away from the handles. Other blades may fit by peg and socket engagement. The tool may have detachable rollers enabling the tool to advance at a controlled elevation along a wall being formed and shaped. A slide block may be arranged to engage the rollers so as to adjust their position on the tool. The tool may have integral bubble levels.
