Abstract: A bionic fixing apparatus is provided. The bionic fixing apparatus includes a flexible portion having at least one trench. The trench is disposed on the surface of the flexible portion and has a first end and a second end. An interval is disposed between the first end and the second end. The trench is disposed for spreading the stress applied on the bionic fixing apparatus and preventing stress concentration and stress shielding.

Abstract: An additive manufacturing method for a 3D object is provided and includes (a) providing a 3D digital model of the 3D object; (b) dividing the 3D digital model into repeat arrangement of at least one type of polyhedral 3D units and an X-Y plane is an acute angle or an obtuse angle; (c) cutting the 3D digital model along a Z-axis into a plurality of 2D slices; (d) defining a scanning path covering one of the 2D slices; (e) providing an energy beam to a material on a working plane along the scanning path to form a construction layer corresponding to the one of the 2D slices; and (f) repeating the steps (d) and (e) to build up the 3D object by adding a plurality of construction layers in sequence.
