Abstract: A bionic fixing apparatus is provided. The bionic fixing apparatus includes a body having a through hole and at least one slit. The through hole penetrates the body from the top surface to the bottom surface to form a top opening and a bottom opening. An inner diameter of the top opening is larger than an inner diameter of the bottom opening. The slit is connected to the bottom opening and extends upwardly from the bottom surface of the body, such that the body has a flexible bottom portion.

Abstract: An additive manufacturing system is provided. The system includes: a stage, a powder supplying device, an energy beam generating device and an atmosphere controlling module. The powder supplying device provides powder to the stage. The energy beam-generating device generates an energy beam and directs the energy beam to the stage. The atmosphere controlling module includes at least one pair of gas inlet-outlet devices coupled around the stage, and a dynamic gas flow controlling device connected with the gas inlet-outlet devices. The dynamic gas flow controlling device dynamically controls an angle between a flow direction of the gas and a moving direction of the energy beam. The angle is predetermined by a scanning strategy.
