THREE-DIMENSIOANL PRINTING METHOD AND THREE-DIMENSIONAL PRINTING APPARATUS THEREOF

摘要

A 3D printing method and a 3D printing apparatus using the same are provided. The method includes following steps. A printing section is obtained according to printing information of a 3D object, where the printing section includes N-layer of casing layers and a single layer of a filling layer. A feeding rate of the printing head is respectively adjusted to a first value and a second value, where the second value is N times of the first value, and N is a positive integer greater than 1. The printing head is controlled to print the casing layers on a carrying surface of the printing platform according to the first value, and is controlled to print the filling layer according to the second value. A thickness of the single layer of the filling layer of the printing section is consistent with a total thickness of the N-layer of the casing layers.
