摘要： A 3D printing method is provided. A stereolithography 3D printer (2) selects one of multiple layers of print data sequentially, makes a modeling plane be a default thickness (h) away from a material tank (23), irradiates heading to the modeling plane according to the selected layer of the print data for printing one layer of slice physical model (421-422, 431-433), makes the modeling plane detach from light-curable materials (41) in the material tank (23), rotates the material tank (23) for making an angle difference between angles before and after rotation be within a default angle interval, and performs above steps repeatedly until completion of a 3D physical model.

摘要： A 3D printing device including a base (110), a gantry (120), a forming platform (140) movably assembled to the gantry, a tank (130), an adjustable platform (170), a driving module (150) and a control module (160) is provided. The gantry and the tank are respectively disposed on the base. The adjusting platform is disposed between the gantry and the forming platform or between the tank and the base. The driving module is connected to the forming platform and the gantry. The control module is electrically connected to the driving module to drive the forming platform to reciprocate along the gantry, so that the forming platform is moved into or out of the tank. Before 3D printing is performed, the control module moves the forming platform to lean against the tank through the driving module, so as to drive the adjustable platform to deform, and confirm consistency of contact surfaces of the forming platform and the tank.

摘要： A formation tank (10) includes a tank body (100) and a release film (200). The tank body (11) includes a bottom plate (100) and a tank wall (12). One face of the bottom plate (100) is an inner bottom surface (101), and at least one engagement structure (110) is formed on the inner bottom surface (101). The tank wall (12) protrudes from the inner bottom surface (101) and surrounds a periphery of the bottom plate (100). The release film (200) is attached on the inner bottom surface (101) and the release film (200) is mortise-and-tenon connected to the engagement structure (110). An engagement structure (110) is arranged on the bottom plate (100) to improve an engagement force between the bottom plate (100) and the release film (200). Accordingly, the release film (200) is prevented from being detached, and therefore durability of the release film (200) is also improved.
