  • Patent number: 10730282
    Abstract: In an example, a method includes forming, at an additive manufacturing apparatus, a first layer of build material to be processed in the generation of an object. A print agent is selectively applied onto the first layer based on a first print instruction associated with the first layer. Energy is applied to the first layer to cause fusion in a region of the first layer. The method further comprises: measuring the temperature of the first layer at a plurality of locations to form a measured temperature distribution profile; comparing the measured temperature distribution profile against a predicted temperature distribution profile to generate a difference; and correcting a temperature distribution profile of a subsequent layer of the build material following fusion of the subsequent layer based on the difference by modifying a second print instruction associated with the subsequent layer.

  • Patent number: 10399269
    Abstract: A three dimensional (3D) printer and method for dispensing a material to form a 3D substructure and for dispensing an adhesive onto the 3D substructure. The adhesive printed onto the 3D substructure may be used to attach the 3D substructure to another substructure such as a conventionally formed substructure or another 3D printed substructure. Printing the adhesive using the 3D printer during the same 3D manufacturing process used to print the 3D substructure may improve precision of the location at which the adhesive is dispensed, thereby improving the quality of superstructure created by joining the substructures. An embodiment of the present teachings may decrease the overall time and cost to attach substructures.

  • Patent number: 10384436
    Abstract: The invention relates to a method and a production line (10) for making tangible products by layerwise manufacturing. Layers of a uniform thickness are deposited on top of each other and solidified in a pattern that corresponds to a cross section of the product. The method and production line are in particular suited for making mutually different products out of powders of construction material. The construction material is deposited on the different building platforms (11,12) individually by a deposition head (13). A surplus of material is removed by a remover (14), preferably before the layer is solidified (15). This allows that the quantity of material can be adapted to the specific product on each building platform. The production line further comprises a platform conveyor (16) for conveying the towards and away from the deposition head repeatedly.
