Abstract: A design with multiple instances of a three-dimensional article is printed by first defining a unit cell that includes a single instance of a three-dimensional article that repeats in the design along with its nearest neighbor elements in both a plane of a build plate of a target printer on which the design is to be printed and a plane orthogonal thereto. The design is represented in an output file of a design application and a slicer application then generates instructions to manufacture the design by the target printer. The instructions (g-code) include directions to print, for each of a specified number of layers a number of instances of the unit cell that can be accommodated within a build envelop of the target printer per layer as determined by said slicer application. The design is printed by the printer according to the instructions from the slicer application.

Abstract: A hierarchical resource management system for a building includes one or more processors. The processors implement a plurality of agents that each monitor sensed values, and generate operating scenarios based on the sensed values for corresponding resources. The processors also implement a coordinator that filters the operating scenarios to remove the operating scenarios that violate internal laws of the agents to form an aggregate validated set of operating scenarios. The processors further implement a supervisor that, responsive to receipt of target conditions for the zones and the aggregate validated set of operating scenarios from the coordinator, selects a combination of the operating scenarios from the aggregate validated set of operating scenarios that achieves target conditions and minimizes overall energy consumption by the resources such that some of the operating scenarios of the combination do not minimize energy consumption of the resources corresponding to the some of the operating scenarios.

Abstract: According to some aspects, calibration techniques are provided that allow an optics module of an additive fabrication device to be installed and operated in a stereolithography device by a user. In particular, the calibration techniques enable the optics module to be calibrated in a way that only depends on the characteristics of the optics module, and not upon any other components of the stereolithography device. As a result, the techniques enable a user of a stereolithography device to remove one optics module and replace it with another, without it being necessary to repair or replace the whole device. In some cases, the calibration techniques may include directing light onto one or more fiducial targets within the stereolithography device and measuring light scattered from said targets.

Abstract: A method operates a three-dimensional (3D) metal object manufacturing system to compensate for errors that occur during object formation. In the method, thermal image data and dimensional image data of a metal object being formed by the 3D metal object manufacturing system is generated prior to completion of the metal object. Thermal conditions are identified from these data and compared to predetermined ranges corresponding to the identified thermal conditions to identify one or more errors. For identified errors outside a corresponding predetermined difference range, the method performs an error compensation technique. The error compensation includes modification of a surface data model, modification of machine-ready instructions, or operation of a subtractive device.

Abstract: Examples herein relate to assigning, by a system agent of a central processing unit (CPU), an operating frequency to a core group based priority level of the core group while avoiding throttling of the system agent. Avoiding throttling of the system agent can include maintaining a minimum performance level of the system agent. A minimum performance level of the system agent can be based on a minimum operating frequency. Assigning, by a system agent of a central processing unit, an operating frequency to a core group based priority level of the core group while avoiding throttling of the system agent can avoid a thermal limit of the CPU. Avoiding thermal limit of the CPU can include adjusting the operating frequency to the core group to avoid performance indicators of the CPU. A performance indicator can indicate CPU utilization corresponds to Thermal Design Point (TDP).
