Abstract: Closure device suitable for a 3D printing device and/or coater device, comprising a closure means, wherein the closure means is activatable and can be opened by activating means, wherein the activating means is an eccentric, a draw key and/or a slotted link. The invention also relates to a method and a device for producing 3D mouldings, wherein such a closure device is used.

Abstract: The invention relates to a method and a device for applying fluids, particularly in a method for producing three-dimensional shaped parts, wherein a coating device comprising a blade, a fluid outlet and a reservoir is provided, and the blade is displaced across the working field such that it can implement a rotational movement type vibration, said vibration occurring as the result of a stroke by a linear actuator.

Abstract: The present invention relates to a device for manufacture of three-dimensional models by means of a 3D printing process, whereby the build material is deposited on a build platform in layers and the build platform is moveable in the Z-direction and one or several drive units and one or several guide elements is/are provided to move the build platform. In so doing, drive units and guiding elements are arranged in such a way that a movement of the drive units is decoupled from the movement of the guiding elements.

Abstract: In a pump chamber connected to a liquid supply, an overlapping piezoelectric flexural transducer is disposed so that when voltage pulses are applied to produce an excursion, a number of droplets can be expelled from a nozzle array in the housing wall of the pump chamber using a plurality of nozzles. Gaps are formed between the edges lateral to the direction of overhang an the free end of the piezoelectric flexural transducer ad adjacent section of the housing wall. The nozzle array can be disposed in the projection of the plate surface of the piezoelectric flexural transducer in its direction of motion or in the extension of the piezoelectric flexural element or in another suitable pattern. As part of a combustion device the droplet mist generator is excellent for producing a combustible fuel-oxidant mixture.
