Patent number: 9649814Abstract: A 3D scanning-printing device includes a platform, a processor, a reflecting module, a projector and a 3D printing module. The platform carries an object. The processor is electrically connected with the platform, the reflecting module, the projector and the 3D printing module. The processor controls the reflecting module to move between a first position and a second position. When the reflecting module is located at the first position, the projector projects a structured light to the object so as to produce 3D spatial information. The processor receives the 3D spatial information and produces 3D printing information. When the reflecting module is located at the second position, the projector projects a cutting layer image according to the 3D printing information, and the reflecting module reflects the cutting layer image to the 3D printing module.Type: GrantFiled: November 25, 2014Date of Patent: May 16, 2017Assignee: DELTA ELECTRONICS, INC.Inventor: Hsin-Tsung Yeh

Patent number: 7972016Abstract: A projector system includes a light source module and an integrator including a light receiving surface for receiving light from the light source module. The light source module includes a number of light sources for emitting parallel light, multiple sets of light-adjusting prisms corresponding to the light sources and a focusing lens arranged near the integrator. Light emitted from each of the light sources is refracted by the corresponding set of light-adjusting prisms, and then focused by the focusing lens to the light receiving surface of the integrator, and forms into a converging light cone with the apex being at the light receiving surface of the integrator. An angle of the light cone is 1/N of a cone formed by the light without being refracted, where N is number of the light sources and is greater than 1.Type: GrantFiled: August 4, 2008Date of Patent: July 5, 2011Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Hsin-Tsung Yeh, Chun-Hsiang Huang
