Abstract: A 3D printing system comprising: a selective solidification module to: form a printed article by processing a build material; and form a printed container encompassing the printed article and a portion of unused build material about the printed article, the printed container defining a first port and a second port fluidly connected to the first port. The 3D printing system further comprises a connector to couple to the first port or second port of the printed container; and a pump fluidly connected to the connector to cause a fluid to flow through the printed container from the first port to the second port such that the printed article is cooled by the fluid flow.

Abstract: A method and apparatus is described in which a signal indicative of an operation of a energy source of a 3D printer during a second predetermined time period commencing with the end of a first predetermined time period is obtained, the first predetermined time period commencing with an activation of the energy source, wherein the energy source is active throughout the first and second time periods; the obtained signal is compared with a reference signal; and it is determined, based on the comparison, whether the energy source is operating according to predetermined characteristics.

Abstract: Example implementations relate to an apparatus to control supplying power to a linear load; the power having a predetermined current profile; the apparatus comprising a controller to establish synchronisation information associated with an AC input voltage of an AC supply; and produce at least one pulse width modulation signal in response to the synchronisation information and a target instantaneous current of the predetermined current profile; and at least one output to output the at least one pulse width modulation signal to a current modulator for controlling current to the linear load.
