1. A method for manufacturing a component involving direct energy deposition by
stacking layers of material that are each obtained by depositing and melting, continuously, a material in an impact zone targeted by an energy beam,
the material coming from a material supply system configured to occupy an activated state in which the material supply system supplies the impact zone with material and a deactivated state in which the material supply system no longer supplies the impact zone with material,
the energy beam being emitted by a focused energy source configured to occupy an activated state in which the focused energy source generates the energy beam and a deactivated state in which it does not generate the energy beam,
the energy beam having at least one feature controlled by an energy beam input current,
wherein the manufacturing method comprises the steps of:
monitoring the energy beam input current,
comparing the monitored energy beam input current with a given threshold current above which energy runaway occurs, and
stopping the manufacturing method when the energy beam input current is above the given threshold current.
