Claim:
1. A method for controlling a three-dimensional printing apparatus, applicable for controlling a tank of the three-dimensional printing apparatus, wherein the three-dimensional printing apparatus is adapted for printing a three-dimensional object relating to a three-dimensional model, the method comprising: obtaining a plurality of layer objects of the three-dimensional object according to the three-dimensional model, wherein the layer objects comprise a first layer object; searching a reference layer object from the object layers, wherein the reference layer object is stacked above the first layer object along an z-axis; comparing the cross-section information of the first layer object with reference cross-sectional information of the reference layer object to obtain a structural friability level of the first layer object, determining a swing velocity of the tank according to the structural friability level; controlling a light source to project light on liquid curing material in the tank, such that the first layer object is cured on a bottom of the tank; and controlling the tank to swing according to the swing velocity corresponding to the first layer object, such that the cured first layer object is separated from the bottom of the tank.
