Abstract: A method includes a computer receiving a fulfillment request associated with one or more items. Responsive to receiving the fulfillment request, the computer determines estimated weight data based on the one or more items in the fulfillment request. The computer obtains actual weight data associated with the fulfillment request for one or more items. The computer verifies that the actual weight data corresponds to the estimated weight data. The computer performs additional processing based on verifying.

Abstract: An additive manufacturing system includes: (a) a build platform dispensing assembly carrying a plurality of build platforms; (b) at least two additive manufacturing apparatus, each apparatus configured for receiving a removable build platform on which objects can be produced; (c) a build platform buffering assembly configured for removably receiving at least one build platform on which an object has been produced; (d) a cleaning apparatus; and (e) a robot operatively associated with each cleaning apparatus, the at least two additive manufacturing apparatus, the build platform dispensing assembly, and the build platform buffering assembly.

Abstract: A method includes: providing a three-dimensional printer including a build surface and a carrier that is movable away from and toward the build surface; advancing the carrier toward the build surface and contacting a lower surface of the carrier with the build surface or a fixture or frame member adjacent the build surface to align the carrier in an aligned position with the lower surface of the carrier parallel to the build surface; and locking the carrier in a locked state to maintain the carrier in the aligned position.
