In recent years additive manufacturing technologies have developed rapidly due to their capability of manufacturing near-net shape parts of complex geometry without dies or substantial machining, resulting in reductions of the lead-time, material waste and costs. Different 3D printing processes are extensively used to produce various kinds of parts including metal ones. Nevertheless, there are still significant obstacles in the production of large-volume components particularly in the efficiency of the process or material use. A major impediment in the application of additive manufacturing at industrial scale and its feasibility within the sustainable business cases is the limitation in component dimensions and low build-up rate of commonly used powder-based methods. The wire and arc-based additive manufacturing is gaining interests due to its capability to produce near-net-shape parts of medium to high complexity at medium to large scale without the need for large, complex tooling using relatively simple and readily available welding equipment and control systems. The arc wire-based additive manufacturing technology, 3D-Metal Print (3DMP®), from GEFERTEC GmbH is a stable and economical process that provides new possibilities for producing large-volume components at industrial scale. High deposition rates, low material and equipment costs and good structural integrity makes the arc-wire-based manufacturing a potentially high beneficial replacement to machining out of solid billets or forging. For the 3DMP® process various kinds of weldable materials can be used. The presented work focuses on different tool steels using flux-cored wire and solid wire in regard of applications in tool-making industry. The material properties of the printed parts have been validated in substantial tests and the possibilities of obtaining good mechanical properties, in particular hardness, and very high density of printed parts from 3DMP® process will be presented in depth.
