Patent number: 10406746Abstract: The invention provides a heating head for a three-dimensional printing pen. The heating head includes a heating pipe, a heating member, a heat insulation pipe, a heat insulation sleeve, and a heat sink. The heating member is disposed on the heating pipe. The heat insulation pipe penetrates into the heating pipe. The heat insulation sleeve is sleeved on the heating pipe and opposite to the heating member. The heat insulation sleeve partly covers the heat insulation pipe, and the heat insulation pipe and the heat insulation sleeve are separated by the heating pipe. The heat sink and the heat insulation sleeve mutually lean against, wherein the heat insulation sleeve is located between the heating member and the heat sink, and the heat insulation pipe penetrates into the heat sink.Type: GrantFiled: March 10, 2016Date of Patent: September 10, 2019Assignees: XYZprinting, Inc., Kinpo Electronics, Inc.Inventor: Hao-Jen Huang

Patent number: 10173411Abstract: A 3-D printing apparatus includes a frame, a tank, an automatic-filling module and a control unit. The tank is disposed in the frame and contains a liquid-forming material. The automatic-filling module includes a sensing unit, a reservoir, a filling pipe and a pressuring unit. The sensing unit detects a liquid level of the tank. The reservoir stores the liquid-forming material. The filling pipe connects to the reservoir and includes an outlet. A maximum liquid level of the liquid-forming material in the reservoir is lower than or equal to a level of the outlet. A gap exists between the outlet and a top edge of the tank. The pressuring unit provides a positive pressure to the reservoir so that the liquid-forming material in the reservoir flows to the tank. The control unit determines whether the pressuring unit provides the positive pressure to the reservoir according to the liquid level.Type: GrantFiled: December 8, 2014Date of Patent: January 8, 2019Assignees: XYZprinting, Inc., Kinpo Electronics, Inc., Cal-Comp Electronics & Communications Company LimitedInventors: Chen-Fu Huang, An-Hsiu Lee, Hao-Jen Huang

Patent number: 9346217Abstract: A three-dimensional printing apparatus including a swing tank containing a liquid formation material, a swing mechanism, an elevating platform, a light source and a control unit is provided. The swing tank includes a pivot side and a swing side adapted to be swung about the pivot side. The swing mechanism includes a cam and a driving motor. The cam leans against the swing side for swinging the same. The elevating platform and the light source are respectively disposed above and below the swing tank. The control unit controls the elevating platform to immerge into the liquid formation material. The light source cures the liquid formation material between the elevating platform and the bottom of the swing tank. The control unit then controls the swing mechanism to swing the swing side, so the cured liquid formation material is separated from the bottom and located on the elevating platform.Type: GrantFiled: September 16, 2014Date of Patent: May 24, 2016Assignees: XYZprinting, Inc., Kinpo Electronics, Inc., Cal-Comp Electronics & Communications Company LimitedInventors: Chen-Fu Huang, An-Hsiu Lee, Hao-Jen Huang
