The disclosure relates to an application device for applying an application medium onto a component, preferably for application of a coating onto a motor vehicle body component. The application device includes a print head for preferably serial and/or permanent application of the application medium, wherein the print head has: a nozzle plate, at least one nozzle in the nozzle plate in order to discharge the application medium, at least one valve element, which is movable relative to the nozzle plate, for control of the application medium discharge through the at least one nozzle, wherein the at least one movable valve element closes the at least one nozzle in a closing position and releases it in an opening position, and at least one drive for moving the at least one valve element. The application device is characterised in particular in that it includes at least one temperature control apparatus for reducing heating of the at least one drive during application of the application medium.

Provided is a vaporizer capable of reducing the occurrence of bumping in a vaporization space and thereby minimizing the pressure fluctuations therein, when a method not using an atomizer is employed. A vaporizer (1) includes a tank body (10), a porous member (30) disposed in the vaporizer (1) and heated, a supply tube (40) configured to supply a liquid material (L) to the porous member (30), and a gas discharge passage (7) configured to discharge a source gas (G) produced by vaporizing the liquid material (L) to the outside. An outlet (41) of the supply tube (40) is disposed in contact with or in close proximity to the porous member (30). When the outlet (41) is disposed in close proximity to the porous member (30), a separation distance (H) between the outlet (41) and the porous member (30) is not greater than a distance from the outlet (41) to a bottom of a droplet of the liquid material (L) formed and suspended at the outlet (41) by surface tension.

An apparatus for applying a first fluid to an advancing substrate comprising a nozzle body made, at least in part, using an additive manufacturing method. The nozzle body comprises a fluid orifice for receiving the first fluid; a conduit in fluid communication with the fluid orifice for receiving the first fluid received by the fluid orifice; a passageway in fluid communication with the conduit for receiving the first fluid received by the conduit; and a slot in fluid communication with the passageway for applying the first fluid to the advancing substrate. A method for making an apparatus comprising a nozzle body is also provided, comprising: sequentially forming, from at least one material using an additive manufacturing method, a plurality of layers in a configured pattern corresponding to a shape of at least one of an upper nozzle assembly member or of a lower nozzle assembly member of the nozzle body.

Methods, systems, and apparatus, for performing additive manufacturing with concrete. One example is an additive manufacturing print head. The print head includes a body defining an internal flow path, a print nozzle at an outlet of the internal flow path, an auger disposed within the internal flow path, a first microwave emitter, and a second microwave emitter. The auger is operable to convey a concrete mixture towards the print nozzle. The first microwave emitter is operable to alter a viscosity of the concrete moisture within the flow path by directing first microwave energy towards the internal flow path. The second microwave emitter is arranged to direct second microwave energy towards the concrete mixture when it exits the print nozzle.
