  • Patent number: 10099421
    Abstract: 3-D printing transfers build material and support from an intermediate transfer belt (ITB) to a platen. The build material is the same as the support material, except that the build material includes a photoinitiator and the support material does not. The platen moves to make contact with the ITB, and the ITB transfers successive layers of build material and support material each time the platen contacts the ITB. The platen and a portion of the ITB that is adjacent the platen are heated prior to the platen contacting the ITB, and the same is exposed so as to crosslink polymers of build material, without crosslinking polymers of support material. The polymers of build material being crosslinked and the polymers of support material not being crosslinked makes the support material selectively soluble in a solvent.

  • Patent number: 10081137
    Abstract: A distributed printing method of a powder-bed type 3D printer is present. The method first generates, for each printing layer of a 3D model file, a color image which is applied to print an outer contour part and a non-color image which is applied to print an internal structure part. The method then calculates replacing information according to a default adjusting module, and adjusts color information of the color image and adhesive information of the non-color image based on the replacing information. Finally, the method combines the adjusted color image and non-color image for generating a final printing image, and executes printing according to the final printing image.

  • Patent number: 10076869
    Abstract: A three-dimensional (3-D) printer includes build and support material development stations positioned to transfer layers of build and support materials to an intermediate transfer surface. A platen having a flat surface is positioned to contact the intermediate transfer surface. The intermediate transfer surface transfers a layer of the build and support materials to the flat surface of the platen as the platen contacts one of the layers on the intermediate transfer surface. A dispenser is positioned to deposit a leveling material on the layer on the platen, and a mechanical planer is positioned to contact and level the leveling material on the layer on the platen to make the top of the leveling material parallel to the flat surface of the platen.

  • Patent number: 10065353
    Abstract: An upstream/downstream process for making map pocket stiffeners formed of extruded material and a wire. The extrusion is drawn through a die of a main extruder forming a main body with a channel and the extrudate is then pulled through a first cooling tank to cool the extrudate and set the profile. The wire is automatically indexed into the channel by a programmable indexing device for proper location and distance between each piece of wire. The extrudate with the wire is re-heated and then pulled through a secondary extruder to encapsulate and seal the wire within the extruded material. The extrudate is cooled in a second cooling tank and passes through a series of rollers to achieve a predetermined shape before being cut and profiled to predetermined lengths and dimensions.

  • Patent number: 10046498
    Abstract: A three-dimensional drawing device can include a housing configured for to be held in user's hand, shaped to allow manipulation of the housing like a pen, and configured to accept a strand of thermoplastic material. The drawing device has a nozzle assembly with an exit nozzle and a motor connected to a gear train that engages the strand such that rotation of the motor causes the feed stock to be extruded out of the exit nozzle to form a three-dimensional object. The motor can be controlled using a variable speed control mechanism or first and second actuators, thereby controlling movement of the strand, for example, to advance or retract the strand relative to the nozzle assembly.
