A consumable material for use in an extrusion-based digital manufacturing system, the consumable material comprising a length and a cross-sectional profile of at least a portion of the length that is axially asymmetric. The cross-sectional profile is configured to provide a response time with a non-cylindrical liquefier of the extrusion-based digital manufacturing system that is faster than a response time achievable with a cylindrical filament in a cylindrical liquefier for a same thermally limited, maximum volumetric flow rate.


A universal adapter (18) for use with a consumable assembly (12) that is configured for use with an additive manufacturing system (10), the universal adapter (18) comprising an inlet opening (46a) configured to receive a guide tube (16) of the consumable assembly (12), and a connection member (52) at the outlet end (50), which is configured interface with a mating panel (44) of the additive manufacturing system (10).


A liquefier assembly (20) for use in an additive manufacturing system (10) to print three-dimensional parts (22), which includes an upstream pressure-generating stage (52) and downstream flow-regulating stage (52). The upstream pressure-generating stage (52) includes a drive mechanism (46), a liquefier configured (52) to melt a consumable material (48) receive from the drive mechanism (46) to produce a molten material in a pressurized state. The downstream flow-regulating stage (52) includes a gear assembly (52) having a casing assembly (64,66,68) and a pair of gears (74,76) disposed within the interior cavity (78,80) and engaged with each other to regulate a flow of the pressurized molten material (48) through the gear assembly (52) for controlled extrusion.


A method and system (10) for printing a three-dimensional part (74), which includes producing a developed layer (64) of a part material with one or more electrophotography engines (12) of an additive manufacturing system (10), transferring the developed layer (64) from the one or more electrophotography engines (12) to a transfer assembly (14) of the additive manufacturing system (10) sintering the developed layer (64) at the transfer assembly (14) to produce a sintered contiguous film (64F), cooling the sintered contiguous film (64F) down to a transfer temperature, and pressing the cooled sintered contiguous film (64F) into contact with an intermediate build surface (76) of the three-dimensional part (74) with a low applied pressure.

A material composition, which may be a support material, for three-dimensional (3D) inkjet printing is disclosed. The material composition may comprise a glycol polymer, a low molecular weight polar substance and a surface-active agent. The glycol polymer may be polyethylene glycol (PEG) having a molecular weight between about 1000 and about 6000 and the low molecular weight polar substance may be dimethyl hexanediol.


A method for building a three-dimensional object containing an identification-tag insert, the method comprising performing a build operation to form layers of the three-dimensional object using a layer-based additive technique, placing the identification-tag insert on at least a portion of the layers during the build operation, and reading information from the identification-tag insert.


A method and system (10) for printing a three-dimensional part (86), which includes rotating a transfer belt (22) with a developed layer (64), scanning the developed layer (64) on the rotating transfer belt (22), pressing the developed layer (64) into contact with an intermediate build surface (88) of the three-dimensional part (86) retained on a moveable build platform (80), scanning the pressed layer on the three-dimensional part (88), comparing the scanned layers to detect an overlay error, and adjusting a position of the moveable build platform (80) relative to the transfer belt (22) to reduce the overlay error for a subsequent developed layer.


A system (100) for building a three dimensional object includes a powder delivery station (10) for applying a layer of powder material on a building tray (200), a digital printing station (30) for printing a mask pattern on the layer, a sintering station (50) for selectively sintering the portion of the layer that is defined by the mask to be sintered and a stage (250) for repeatedly advancing the building tray (200) to each of the powder delivery station, digital printing station and sintering station to build a plurality of layers that together form the three dimensional object. The mask pattern defines a negative portion of the layer to be sintered. Optionally, the system includes a die compaction station (40) for compacting per layer of powder material.


A support material for printing a support structure with an electrophotography-based additive manufacturing system, the support material including a composition having a charge control agent and a thermoplastic copolymer having aromatic groups, (meth)acrylate-based ester groups, carboxylic acid groups, and anhydride groups, with a high anhydride conversion. The composition is provided in a powder form having a controlled particle size, and the support material is configured for use in the electrophotography-based additive manufacturing system having a layer transfusion assembly for printing the support structure in a layer-by-layer manner, and is at least partially soluble in an aqueous solution.


Methods for fabricating three-dimensional objects by 3D-inkjet printing technology are provided. The methods utilize curable materials that polymerize via ring-opening metathesis polymerization (ROMP) for fabricating the object. Systems suitable for performing these methods and kits containing modeling material formulations usable in the methods are also provided.
