A layering device for preparation of layers being formed in additive manufacture, each layer formed by printing a mold wall to define a mold space and filling the mold space with a paste to form the layer. The layering device comprises a roller to press the mold wall from above to form a mold layer surface in a plane, a paste applicator and a blade to spread the paste to fill the mold space. The blade is aligned into the plane to smooth the paste flush with the mold layer surface.

A three-dimensional shaped article producing composition is provided and contains a plurality of particles, a solvent for dispersing the particles, and a binder having a function to temporarily bind the particles to one another in a state where the solvent is removed, wherein a volume-based average particle diameter of the particles is 0.1 μm or more and less than 50 μm, and a content ratio of the binder is 1.5 vol % or more and 10 vol % or less.

In various embodiments, a microreactor features a corrosion-resistant microchannel network encased within a thermally conductive matrix material that may define therewithin one or more hollow heat-exchange conduits.

A three-dimensional device is fabricated in a layer-by-layer approach using a support material. The support material is deposited in a liquid form on a surface, hardened by cooling or ultraviolet (UV) curing, and selectively ablated to create an area within which the desired structure of the device will be formed. Active material is deposited into this area, and the layer-by-layer process repeated until the three-dimensional device has been completed. Thereafter, any remaining support material is removed by water or other solvent.

A lamella block is provided for a calibrating device for calibrating an extruded profile, wherein the lamella block includes a carrier structure and a lamella structure, and wherein the lamella structure has a plurality of lamellae, which are spaced apart from each other by grooves and arranged in a longitudinal direction (L) of the carrier structure. Neighboring lamellae of the lamella block are arranged laterally offset to each other in the longitudinal direction (L). Also provided is a method for manufacturing the lamella block mentioned above, as well as a calibrating device, which includes a plurality of the lamella blocks mentioned above. Further provided is a system for additively manufacturing the lamella block mentioned above, a corresponding computer program and a corresponding dataset.
