Abstract: A release device and a printing apparatus are provided. The release device includes: a fixing member, a release film, a support plate, a soft rubber ring and an exhaust device. The fixing member is arranged to be fixed to the release film. The soft rubber ring is arranged between the release film and the support plate at edges of the release film and the support plate. A cavity is enclosed by the release film, the support plate, and the soft rubber ring together. The support plate is provided with a first through hole through which the exhaust device is in communication with the cavity. In this way, air in the cavity can be exhausted by the exhaust device, the release film can be attached downward to the support plate, a printing model can thus be smoothly released from the release film.

Abstract: A three-dimensional printing device includes a cantilever, a platform, and a leveling device. The leveling device includes a connecting piece and an adjuster. A first end of the connector is provided with a spherical connecting part, and a second end of the connector is detachably connected to the platform. The side of the cantilever adjacent to the connector is recessed inwards to form a accommodating cavity, and the spherical connecting part is accommodated in the accommodating cavity. The adjuster is configured to move between a first position and a second position. In the first position, the adjuster passes through the connector and is fixedly connected to the cantilever, thus the platform is fixed to the cantilever by the leveling device. In the second position, the adjuster is separated from the cantilever, the platform can be rotatably connected to the cantilever by the leveling device.

Abstract: Disclosed are a feeding device and a 3D printing apparatus. The feeding device includes a resin vat, a driving device and a conveying device. The driving device is connected to the resin vat, the driving device is connected to a container filled with a resin liquid through the conveying device, and the interior of the container is further in communication with the resin vat through the conveying device. When the height of the resin liquid inside the resin vat is lower than a first preset height, the driving device inputs gas into the container through the conveying device, such that the resin liquid inside the container is conveyed into the resin vat through the conveying device, thereby achieving automatic feeding to avoid a model printing failure due to lack of the resin liquid.
