Abstract

Metal additive manufacturing is currently experiencing strong growth in the industry. Until recently, it remained confined to small dimensions, a consequence of the limits imposed by the technologies used (mainly PBF (Powder Bed Fusion) technology). Today, suppliers offer large PBF machines using numerous lasers to ensure sufficient manufacturing speeds. Furthermore, another large-scale offer is based on the use of DED (Directed Energy Deposition) processes which use an energy source (for example Laser) to melt a deposited filler material to form the volume layer after layer. of the room. IREPA LASER has therefore developed a new technology capable of manufacturing or repairing XXL parts (up to 5 meters in length and weigh up to 5 tonnes). This technology is based on a head for depositing one or more molten metal wires using a high-power laser (10kW). This presentation will be an opportunity to take stock of the evolution of additive manufacturing technologies, and to present the latest results obtained in the field of DED, but also to show that the laser has become essential in manufacturing industries.
