Abstract: A method for fabricating a medical device includes steps as follows: A degradable powder including at least one metal element is firstly provided on a target surface. A focused energy light bean is applied to sinter/cure the biodegradable powder within an oxygen-containing atmosphere; wherein the oxygen concentration of the oxygen-containing atmosphere is adjusted to provide a first oxygen concentration and a second concentration when the focused energy light is driven to a first location and second location of the target surface respectively. The aforementioned processes are then repeatedly carried out to form a three-dimensional (3D) structure of the medical device.
