Abrégé

A control system for regulating an additive manufacturing process of an additive manufacturing apparatus, the apparatus configured to add metal to a substrate by means of metal deposition. The apparatus comprises: a nozzle for output of a metal strip, the nozzle configured to be arranged at a distance from the substrate, and configured to move relative the substrate in XYZ-axes via a position actuator. The apparatus further comprises a heat source configured to melt the metal strip into a weld pool on the substrate, and an electrical power source configured to supply current via the metal strip 20 to the substrate. The control system is configured maintain process stability, during the deposition of a layer of metal, via: determining electrical conductance between the metal strip and the substrate by measuring at least one electrical property of the supplied current; determining the difference between the determined electrical conductance, and a desired electrical conductance; and, adjusting at least one of: the substrate to nozzle distance, the speed of the nozzle movement relative the substrate, the amount of supplied current, the heat provided by the heat source, and/or the rate of output of the metal strip, based on the difference between the determined conductance and the desired conductance.
