Abstract: A method is disclosed in which print instructions for a 3D print job are received which including a plurality of layers to be printed on a layer-by-layer basis to form a 3D object. The print instructions are executed using at least one nozzle whilst performing a nozzle test in a plurality of layers of the 3D print job. The nozzle test results for each layer of the plurality of layers is compared to stored nozzle data. A current nozzle health status is determined based upon the comparison. A corrective action is triggered if the health status is non-compliant with a pre-determined threshold. An apparatus and a machine-readable storage medium comprising instructions executable by a processor are also disclosed.

Abstract: A control system for controlling actuators comprises a central processor, a plurality of actuators, and a plurality of servo systems for controlling the respective actuators. Each servo system is operable, independently of the central processor, to control a controlled parameter (Y) in accordance with a reference value (R). The servo systems and the central processor communicate via a non-deterministic communications system. The central processor and the servo systems provide, to the central processor via the non-deterministic communications system, offset signals representing offsets (R−Y) measured by the servo systems between reference R and actual Y values of the controlled parameter. The central processor compares the offsets (R−Y) measured by the respective servo systems one with another.

Abstract translation: 用于控制致动器的控制系统包括中央处理器,多个致动器以及用于控制各个致动器的多个伺服系统。 每个伺服系统可独立于中央处理器操作,以根据参考值(R)控制受控参数(Y)。 伺服系统和中央处理器通过非确定性通信系统进行通信。 中央处理器和伺服系统通过非确定性通信系统向中央处理器提供偏移信号,表示伺服系统在参考R和受控参数的实际Y值之间测量的偏移(R-Y)。 中央处理器将由相应的伺服系统测量的偏移(R-Y)与另一个相比较。

Abstract: An example method to determine an excess of build material in 3D printing includes providing an amount of build material, spreading the amount of build material to form a layer of build material on a build platform and to leave any excess build material on an excess zone having visible marks thereon and analyzing the marks on the excess zone to determine an excess of build material at the excess zone.

Abstract: A method of printing an envelope for encapsulating at least one 3D printed object, the envelope allowing for removal of the at least one 3D printed object from an additive manufacturing system, the method comprising: monitoring a printing queue for one or more print jobs; determining a size of at least one dimension of the envelope based on the size of the one or more queued print jobs; commencing printing of the one or more queued print jobs and the envelope; and varying the size of the at least one dimension in response to changes in one or more print jobs in the printing queue.
