Tank assembly and components thereof for a 3D printing system

A tank assembly (10, 12) for a 3D printing system may include a membrane assembly (48, 50) that is releasably secured to a bottom rim (14) of a tank sidewall (12, 13) of the tank assembly (10, 12). The securing mechanism may include one or more of a friction-fit coupling and a magnetic coupling. The...

Zusammenfassung:	A tank assembly (10, 12) for a 3D printing system may include a membrane assembly (48, 50) that is releasably secured to a bottom rim (14) of a tank sidewall (12, 13) of the tank assembly (10, 12). The securing mechanism may include one or more of a friction-fit coupling and a magnetic coupling. The membrane assembly (48, 50) may include a frame (50, 52, 80, 82), a radiation-transparent flexible membrane (72, 74) and a membrane securing member (100, 76, 78). A peripheral portion (74) of the flexible membrane (72, 74) may be secured within a groove (16, 62) of the frame (50, 52, 80, 82) by the membrane securing member (100, 76, 78). The tank sidewall (12, 13) may include one or more components for supplying fresh resin (26, 30, 34, 44, 4) to the tank assembly (10, 12) and one or more components for draining used resin (26, 30, 34, 44, 4) from the tank assembly (10, 12).
