Abstract: A print engine of an additive manufacturing system can include an XY galvo arranged to direct a laser beam toward multiple positions on a print bed following a print path. In one embodiment an XY gantry supporting the XY galvo is connected to a motion control system that supports dynamic adjustment of the cycle time for both the XY gantry and XY galvo.

Abstract: The present invention relates generally to a method of diagnosing, predicting or monitoring the development or progress of heart failure in a mammal and, more particularly, to a method of diagnosing, predicting or monitoring the development or progress of congestive heart failure in a mammal. The present invention contemplates a method for detecting heart failure by screening for the systemic presence of pulmonary surfactant protein in a subject. The present invention further provides a method for diagnosing or monitoring conditions associated with or characterised by the onset of heart failure, in particular congestive heart failure. Also provided are diagnostic agents useful for detecting one or more surfactant proteins.
