Abstract: A system and a method for a constant micro dosing of powder material, comprising a control device,a cylinder comprising a first opening and a piston movably arranged inside the cylinder and controllable by the control device, wherein the piston is movable in the direction to or away from the first opening along a piston stroke direction. The cylinder is configured for storing the powder material between the piston and the first opening. The piston is configured for pushing the powder material through the first opening by moving along the piston stroke direction. Further the system and the method comprise a removing device for removing the powder material which is pushed out of the first opening of the cylinder. The control device is configured for controlling the piston and the removing device in a synchronized manner such that a predetermined amount of powder material pushed through the first opening is removable by the removing device.
