Patent number: 9415548Abstract: A feeding apparatus for forming 3D object includes a frame structure, a transmission set, an actuator, a swing unit and a controller having a sensor. The feeding apparatus is arranged on a 3D printer equipped with printing mechanism and a filament spool. When the filament is fed into a passageway of the frame structure to push the swing unit, the sensor senses the displacement of swing unit to generate a sensing signal. The controller controls the actuator to drive the transmission set according to the sensing signal, whereby the wire can be smoothly fed into the printing mechanism.Type: GrantFiled: December 4, 2014Date of Patent: August 16, 2016Assignees: XYZPRINTING, INC., KINPO ELECTRONICS, INC., CAL-COMP ELECTRONICS & COMMUNICATIONS COMPANY LIMITEDInventors: Yang-Teh Lee, Yi-Chin Tang

Patent number: 9216545Abstract: A printing head module includes a bracket, a locking mechanism disposed on the bracket and a printing head. The bracket includes a containing cavity and a supporter. The locking mechanism includes a pressing component fixed to the supporter, a locking component and an elastic component. The locking component pivoted to the pressing component such that the elastic component leans therebetween. The locking component has a first positioning portion. The printing head detachably disposed in the containing cavity includes a second positioning component. The first positioning portion is engaged with the second positioning component, so the elastic component is pressed to provide the locking component a restoring force away from the pressing component to confine the printing head between the locking component and the bracket.Type: GrantFiled: March 26, 2014Date of Patent: December 22, 2015Assignees: XYZprinting, Inc., Kinpo Electronics, Inc., Cal-Comp Electronics & Communications Company LimitedInventors: Yang-Teh Lee, Chien-Chih Chen, Yi-Chin Tang, Ying-Chi Hsu

Patent number: 9162395Abstract: A 3-D printing apparatus is configured to make a modeling material form a 3-D object layer by layer. The 3-D printing apparatus includes a printing assembly and a cleaning unit. The printing assembly includes a feeding tube, a nozzle and a driving wheel set disposed between the feeding tube and the nozzle to drive the modeling material transferred to the nozzle from the feeding tube and then exiting from the printing assembly via the nozzle so as to form a 3-D object layer by layer. The cleaning unit has a brush, in which the brush leans against on the driving wheel set to clean out the residual modeling material while the driving wheel set rotates relatively to the cleaning unit.Type: GrantFiled: March 18, 2014Date of Patent: October 20, 2015Assignees: XYZprinting, Inc., Kinpo Electronics, Inc., Cal-Comp Electronics & Communications Company LimitedInventors: Yang-Teh Lee, Yi-Chin Tang
