Abstract: A method and system for manufacturing a three-dimensional porous structure. Filaments are deposited in a predetermined interconnected arrangement in a plurality of stacked layers for forming a porous structure with interconnected pores. A pressure value indicative of a pressure being applied on the build material in the build material reservoir of a nozzle used for deposition is monitored during deposition of the filaments. The processing unit is configured to adjust at least one extrusion parameter in order to compensate for the irregular rising and/or falling of the pressure value.

Abstract: A three-dimensional porous catalyst, catalyst carrier or absorbent monolith of stacked strands of catalyst, catalyst carrier or absorbent material, composed of alternating layers of linear spaced-apart parallel strands, wherein the strands in alternating layers are oriented at an angle to one another, wherein the distance between inner spaced-apart parallel strands is larger than the distance between outer spaced-apart parallel strands in at least a part of the layers of the monolith.

Abstract: Process for producing shaped bodies of catalysts, catalyst supports or adsorbents by microextrusion in which a pasty extrusion composition of a shaped body precursor material is extruded through a movable microextrusion nozzle and through movement of the microextrusion nozzle a shaped body precursor is constructed in layerwise fashion and the shaped body precursor is subsequently subjected to a thermal treatment, wherein for construction of each shaped body precursor the pasty extrusion composition is simultaneously extruded through a plurality of microextrusion nozzles.
