These bolts are rotated to abut on the abutting part, so that the relative position between the rear plate and the motor fixing member can be adjusted. | 04-07-2016 |
20160101617 | FUSED DEPOSITION MODELING INCLUDING COLOR APPLIED TO A DEPOSITED BEAD - Embodiments generally relate to a system for color printing on 3D printed objects. In one embodiment, a ring of ink jet emitters is positioned around an extruder head but out of the build plane. By coordinated emission of ink that is focused on one or more portions of a bead of material deposited by a 3D printer head, colored points can be created on the surface of the bead or “road” formed by successive or continuous deposition of material by the extruder head. | 04-14-2016 |
20160129631 | THREE DIMENSIONAL PRINTING APPARATUS - A three dimensional printing apparatus is provided. The three-dimensional printing apparatus includes a tank, a rotatable platform, a light source module and a controller. The rotatable platform is elevatably disposed above the tank, and the light module is disposed under the tank. When the controller controls the rotatable platform elevating to a height along an axis direction, the controller controls the rotatable platform rotating a plurality of rotating angles in sequence around the axis direction and controls the light source module irradiating liquid-formation material, so as to sequentially solidify a plurality of object sections of a single layer object. | 05-12-2016 |

20160144569 | 3-D PRINTER - A three-dimensional (3D) printing device has at least one collapsible vertical or horizontal axis using a scissor lift mechanism. One of the horizontal axis's can be made operable via a track or path where the entire machine moves along that path via movable wheels or gears. Sensors may monitor the height, orientation, position, and relative distance of the axes, machine, or extruders. Compensating mechanisms such as counterweights, propellers, or gyroscopes may be used to maintain balance, levelness, and control of the system. As a result, the size and weight of the 3D printer is reduced and made easier to transport while maintaining quality build functionality. | 05-26-2016 |
20160159008 | LEAD SCREW GUIDE ASSEMBLY AND THREE-DIMENSIONAL PRINTING APPARATUS - The invention provides a lead screw guide assembly and a three-dimensional (3D) printing apparatus, wherein the lead screw guide assembly includes a base, a first guiding member, a second guiding member and a lead screw guide. The first guiding member is disposed on the base and has a first channel extending along an axis. The second guiding member is movably coupled to the first guiding member along the axis. The lead screw guide is movably disposed on the base along the axis and located in the first channel. The lead screw guide is coupled to the second guiding member, so as to drive the second guiding member to move along the axis and hide in the first channel or protrude from the first channel. | 06-09-2016 |

20160185019 | IMPRINT METHOD, AND IMPRINT APPARATUS FOR IMPLEMENTING THE SAME - An imprint method includes, in the peeling step of peeling a mold off the material layer to be transferred, a region-of-contact recognition operation of recognizing and determining a region of contact of the mold with the material layer to be transferred, a center-of-gravity locating operation of determining a center of gravity of a morphology of the thus recognized region of contact on the basis of that morphology, and a peeling operation of determining a point of force for applying peeling force to the mold or the imprinting substrate in relation to the center of gravity determined by the center-of-gravity locating operation, thereby acting the peeling force on the point of force. | 06-30-2016 |
20160185059 | APPARATUS FOR GENERATING LONG-PERIOD GRATINGS IN OPTICAL FIBER - An apparatus for generating long-period gratings in an optical fiber is disclosed herein. The apparatus includes an intensity adjusting unit and a period adjusting unit that come into contact with a portion of an optical fiber where gratings will be generated. The intensity adjusting unit includes a press part configured to press the portion of the optical fiber where gratings will be generated against a grating generating unit, and an intensity adjusting mechanism configured to apply force to the press part. The period adjusting unit includes a period adjusting mechanism configured to selectively increase and decrease the length of the grating generating unit. | 06-30-2016 |
