Abstract

The disclosure provides a 3D printing apparatus and a 3D printing method which form a 3D object by forming and stacking a plurality of forming layers. The 3D printing apparatus includes a body, a printing module, a curing module, a sensing module and a controlling module. The body has a stage. The printing module sprays liquid forming material on the stage. The curing module cures the liquid forming material on the stage to form a forming layer. The sensing module is configured corresponding to the stage and detects a surface profile of the forming layer according to a condition parameter to generate a profile signal. The controlling module is electrically connected to the printing module, sensing module and curing module. The controlling module receives the profile signal and drives the printing module and the curing module according to the profile signal to remedy the surface profile of the forming layer.
