摘要： A method and system for printing a three-dimensional porous structure (1). Interconnected filaments (2) are deposited in a predetermined arrangement in a plurality of stacked layers (11). The filaments (2) of the consecutive layers (11) are connected to one another to obtain the porous structure (1) with interconnected pores (15). The filaments are deposited in such a way that one or more preselected frangible regions (7) are formed in the arrangement of filaments (2). The one or more frangible regions (7) are connected to less-frangible regions (9) of the porous structure (1). The predetermined arrangement of interconnected filaments (2) is configured such that the one or more frangible regions (7) form structurally weakened zones of the porous structure (1) such that the porous structure (1) breaks along said one or more frangible regions (7) under influence of a load and/or a stress. The plurality of three- dimensional parts (10a) are releasable under influence of the load and/or stress.

摘要： A method and system for controlling an extrusion system (1) having a plurality of nozzle heads (7) for depositing a predetermined interconnected arrangement for concurrently forming individual three-dimensional structures (3) in parallel. An operation of each of the plurality of nozzle heads is monitored in order to detect failing nozzle heads, wherein a first value is calculated which is indicative of an average print time for finishing a number of three-dimensional structures when the print job is continued using one or more non- failing nozzle heads of the plurality of nozzle heads which are still operational, and a second value is calculated indicative of an average print time for finishing the number of three-dimensional structures when the print job is promptly interrupted and a new print job is initiated with the one or more failing nozzle heads of the plurality of nozzles heads being repaired. The controller is configured to restart the print job with the one or more failing nozzle heads being repaired, when the second value is smaller than the first value.

摘要： 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.

摘要： A method and system for manufacturing three-dimensional porous structures. Filaments are deposited in a predetermined interconnected arrangement in a plurality of stacked layers for forming a porous structure with interconnected pores. Furthermore, the porous structure is subjected to a heat treatment in a heat chamber in order to reduce a moisture, solvent and/or organic material, solvent or organic material content (drying and/or calcination) of the porous structure by irradiating microwave energy through said porous structure. The applied microwave energy is selected based on the structural interconnected arrangement of the deposited filaments defining the shape and size of the pores of the three-dimensional porous structure.

摘要： A method and system for manufacturing one or more three- dimensional porous structures (10). Filaments (2) are deposited on a support in a predetermined interconnected arrangement in a plurality of stacked layers (11) for forming one or more porous structure with interconnected pores (15). A nozzle head (30) with a plurality of nozzles (20) is used for depositing filaments. The plurality of nozzles are spaced apart from each other with a predetermined spacing therebetween. Each nozzle has an opening area through which filaments are dispensed as the nozzle head is moved relative to the support. Multiple 3D porous structures are manufactured in parallel, using a subset of nozzles for each porous structure, each subset of nozzles including at least one nozzle. Neighboring subsets of nozzles are distanced in order to provide a working area on which the relevant porous structure of the plurality of porous structures is manufactured.
