  • 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.

  • Patent number: 9258852
    Abstract: A system for melting a substance may be provided. The system may include a crucible insulated with fused silica, a microwave generator configured to supply microwaves, and at least one burner probe extending into the crucible. The at least one burner probe may include a wave guide. The wave guide may be configured to receive microwaves from the microwave generator and transmit the microwaves. The at least one burner probe may further include an absorber. The absorber may have a geometry configured to cause a minimal amount of microwave energy to be reflected back into the wave guide. In addition, the absorber may include a one piece cast of silicon carbide configured to dissipate heat along an exterior of the absorber. The absorber may be further configured to receive the microwaves from the wave guide and convert energy from the microwaves into the heat.

  • Patent number: 9168699
    Abstract: By reversing the direction of a first build material fed into an extruder, the first build material can be wholly or partially evacuated from the extruder before a second material is introduced. This approach mitigates transition artifacts and permits faster, more complete changes from one build material to another.
