A sealing blade includes opposite elongated edges (30, 31) and between them a flat (32) and which is adaptable to a blade holder (17) arranged in a coating applicator (25) of a coating device (21) and into contact with a moving surface (11′). The sealing blade has a contact surface (33), which may be arranged against the moving surface and which is 5-15% of the width (W) of the sealing blade (10).

The invention relates to a spin coater for a device for the additive manufacture of an object, having a support that can be connected to the device in a rotable manner about a rotational axis; and a coating element that is coupled to the support and that is suitable for applying or leveling a powder layer on a plane in the device while the support is rotating, the plane running perpendicularly to the rotational axis. The coating element substantially maintains its orientation during the rotational movement of the support within a specified rotational range. The coating element does not substantially move in a longitudinal direction of the coating element during the rotational movement of the support within a specified rotational range.

A method of generating a building assembly that includes spraying a coating material onto a plurality of pieces of substrate disposed on a first assembly face. The spraying includes spraying the coating material onto the plurality of pieces of substrate via a sprayer configured to apply the coating material to a target surface via a nozzle coupled with a mobile storage container storing the coating material, the coating material impregnating voids of the substrate. The method also includes allowing the coating material impregnating the voids to dry and harden and become rigid to generate the building assembly.

An applicator for dispensing a viscous material from a container. The applicator comprises a nozzle for fluid communication with the container. The nozzle has an outlet at a first end and base in proximity to an opposed second end. The nozzle further includes a support arm spaced apart from the nozzle. The support arm and the nozzle collectively forming a slot therebetween for releasably receiving a blade. An attachment portion extend from the base and is configured to releasably engage the container to permit material within the container to flow under pressure through the nozzle and onto a surface. When the blade is received within the slot, it contacts the material as it exits the nozzle and assists in forming the material into a desired shape or configuration.
