    摘要: The present invention relates to a method of forming a three- dimensional article through successively depositing individual layers of powder material that are fused together so as to form the article, comprising a method of operating a triode electron beam source including a cathode (102), a grid (104) and an anode (106) with the following steps: (a) setting an electron beam current, a cathode heating power, a grid potential Ug and a cathode potential Uc to predetermined start values; (b) reducing the cathode heating power and decreasing a Ug - Uc potential difference for mainintainig a predetermined electron beam current; (c) detecting an X-ray signal emanating from the electron beam source with at least one X-ray detector (190); (d) repeating said reducing and detecting steps until the detected X- ray signal is above a predetermined value; and (e) increasing the cathode heating power by a predetermined safety value above the heating power value which resulted in X-ray signals above said predetermined value. Thereby, the lowest acceptable cathode heating power without affacting the electron beam current is determined and thus the lifetime of the cathode element is prolonged.
