Abstract: A 3D printer configured to print a 3D part includes an ejector having a nozzle that is configured to eject drops of a build material. The 3D printer also includes a build plate positioned below the nozzle. The drops land and solidify on the build plate to form at least a portion of the 3D part. The 3D printer also includes a first heater positioned under or within the build plate. The first heater is configured to heat the build plate and the 3D part thereon. The 3D printer also includes a second heater positioned laterally-offset from the build plate. The second heater is configured to heat a volume of air between the nozzle and an upper surface of the 3D part. The 3D printer also includes an enclosure. The nozzle, the build plate, the first heater, and the second heater are positioned at least partially within the enclosure.

Abstract: Methodologies, systems, and computer-readable media provided for a system for generating personalized electronic documents and verifying user identity are discussed. The system receives user identification data and check information from a user application. The check information is validated by the issuer of the check. The system transmits a notification to the user application that includes a machine readable code. The user application presents the machine readable code and the user identification data to a check-in module and automatic processing of the check is initiated.

Abstract: A system for storage of goods carriers with a rack having storage shelves for the goods carriers on multiple levels, with a rack-servicing machine for storage of goods carriers into the storage shelves and for discharge of goods carriers from the storage shelves. The rack-servicing machine runs along tracks extending the longitudinal extension of the rack, preferably in an aisle between two racks, and is configured to service at least one level, where the goods carriers have at least two pockets correspondingly located in respective opposite side walls configured to allow interaction with the load handler of the rack-servicing machine.
