Printing method for shielding component of 3D model, and calculating method for printing start point of shielding component

摘要

A printing method for shielding component adopted to print a shielding component (2) of a 3D model (20) having multiple printing layers (11) is disclosed. The method first obtains all candidate points of first layer of the shielding component (2) and chooses one of the candidate points as a start point (211) of the first layer according to a default rule, and prints the first layer from the chosen start point (211). Next, the method obtains all candidate points of next layer of the shielding component (2) and chooses one of the candidate points of the next layer which is closest to the start point (211) of last layer to be printed as a start point of the next layer, and prints the next layer from the chosen start point.
