Abstract: The invention relates to an additive manufacturing system (1) and a method for manufacturing one or more three-dimensional structures. At least one deposition unit (3) with one or more nozzles (5) is arranged for dispensing a build material through an opening area thereof on a print surface (7). A controller is provided which is configured to operate the system (1) for deposition of filaments of a build material paste on the print surface (7) in an interconnected arrangement in a plurality of stacked layers in order to form the one or more three-dimensional structures. An actuation unit (9) is arranged in order to have printing access to the at least one deposition unit (3), wherein the actuation unit (9) is configured to hold the print surface. The controller is configured to control the actuation unit (9) so as to move the print surface (7) at the at least one deposition unit (3) during deposition of the filaments by said deposition unit. The one or more nozzles (5) of the at least one deposition unit (3) are arranged to remain stationary during the deposition of the filaments.

Abstract: A three-dimensional porous catalyst, catalyst carrier or absorbent structure of stacked strands of catalyst, catalyst carrier or absorbent material, composed of layers of spaced-apart parallel strands, wherein parallel strands within a layer are arranged in groups of two or more closely spaced-apart, equidistant strands separated by a small distance, wherein the groups of equidistant strands are separated from adjacent strands or adjacent groups of strands by a larger distance.

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: The invention relates to a die (10) for the extrusion of catalyst molding, catalyst support molding, or adsorbent molding (60) in flow direction (32) of an extrudable composition from an entry side (12) to a discharge side (14) of the die comprising a shell (56) and comprising one or more channel-formers (18) which are displacers of the extrudable composition and which extend in flow direction of the extrudable composition, wherein the channel-formers (18) have been metal-printed.
It is preferable that this is free from cavities for receiving extrudable composition which extend at right angles to the flow direction (32) of the extrudable composition, and that this is free from connections running at right angles from channel-formers (18) to the interior side wall (22) of the die (10).
The invention further relates to a process for the production, by means of 3D metal printing, of a metal-printed die (10) for the extrusion of catalyst moldings/support moldings (60).
