A recoater collision prediction and calibration method for additive manufacturing and a system thereof are provided. The recoater collision prediction and calibration method includes the following steps: loading a printing image file to generate a simulated printing object according to the printing image file; performing a process thermal stress simulation on the simulated printing object to obtain a plurality of simulated deformation variables respectively corresponding to a plurality of prediction results of the simulated printing object in a vertical direction on each layer; obtaining an experimental collision height of an experimental printed object; selecting one of the plurality of simulated deformation variables according to the experimental collision height; calculating a recoater tolerance according to the one of the plurality of simulated deformation variables; calibrating a collision risk formula according to the recoater tolerance; and predicting a collision risk value between the simulated printing object and a recoater according to the collision risk formula.

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.
