Large 3D metal printing with powdered laser cladding: Robotic cell with 6 degrees of freedom (gdl) with an additional turning table (1 gdl) for the construction of large components (up to approximately 1m3 in volume) at high deposition rates of up to 6kg/h. Possibility of depositing in external and even internal structures (by means of specific heads) both in a material and in a mixture of materials generating mixtures of materials of variable concentration (' graded materials'). This asset allows us to study different materials, geometries and use cases that can be manufactured by means of laser cladding. The implementation of a closed loop process control system is also offered within the asset in order to optimize the process and detect premature failures in the manufacturing process. Additionally, new nozzle designs and deposition heads can be tested in this cell, as well as the development of deposition paths (CAM) to reduce distortions and geometric failures in the manufactured components.
