An additive manufacturing apparatus includes a support plate and a stage configured to hold a component formed of one or more cured layers of a resin. An actuator assembly is configured to change a relative position of the stage relative the support plate. A radiant energy device is positioned opposite to the stage such that it is operable to generate and project radiant energy in a pattern. A peeling device is positioned downstream of the window. The actuator assembly is configured to move the stage simultaneously with a resin support over the peeling device in an X-axis direction.

The present invention discloses a roll forming device for micro-casting and rolling additive manufacture for large special-shaped pipes, comprises a supporting assembly, a sliding assembly, and a roller system assembly. The sliding assembly includes a guide rail, hydraulic cylinders, hydraulic push rods and a guide rail sliding frame. Two ends of the guide rail are respectively fixedly connected with the centers of two ends of the frame plate in a width direction, the lower surface of the sliding plate of the guide raid sliding frame is slidably connected with the guide rail, housings of the hydraulic cylinders are respectively fixedly connected to the centers at both ends of the frame plate in the width direction. The invention adopts the structures of the guide rail, the hydraulic cylinder and the steering hinge rod to expand the working range of the device and the working types of workable parts.

A molding device includes a movement processing unit configured to move a liquid column sandwiched between two substrates and a molding unit configured to perform a molding process by partially changing the liquid column to a solid within a prescribed molding region.

A 3D printing cleaning module comprises an extraction gate at a lateral wall of a housing; and a platform within the housing to support a build bed including 3D printed parts and un-solidified build material. The platform is tilted or tiltable with respect to a horizontal plane towards the extraction gate to enable 3D printed parts on the platform to be removable through the extraction gate. The module comprises a cleaning engine to remove at least part of the un-solidified build material from the housing, a vibrating mechanism to vibrate the platform; and a controller. The controller is to control the cleaning engine to execute a cleaning operation by removing un-solidified build material from the housing, to cause the part ejection gate to open upon completion of the cleaning operation, and to cause the vibrating mechanism to vibrate the platform when the part extraction gate is in the open position.

A 3D printing module to remove un-solidified build material attached to a 3D printed part is disclosed herein. The 3D printing module comprises a platform within a housing to support a 3D printed part, a vibrating mechanism to vibrate the platform, a cleaning element to apply a cleaning stream within the housing to clean the 3D printed part, and a controller. The controller is to vibrate the platform, generate a cleaning stream in the housing, and to control at least one of the platform and the cleaning element to apply the cleaning stream to different portions of a 3D printed part on the platform.

An additive manufacturing apparatus configured to laminate a plurality of thin films to form a modeled object, the additive manufacturing apparatus including a stage; a roll coater, including a first roll and a second roll, configured to form each of the thin films, the thin film being made of a modeling material, the modeling material being a material of the modeled object; and a drive unit configured to move the roll coater on the stage, the roll coater: is arranged so that the second roll is located on the stage; passes the modeling material between a first roll surface of the first roll and a second roll surface of the second roll; and the drive unit moves the roll coater on the stage in a direction orthogonal to the second axis, and thereby laminates the thin film, formed on the second roll surface, onto the stage.
