Siemens Energy uses additive manufacturing as supplemental technology to manufacture components and part constructions that are difficult to manufacture conventionally. The technology helps the company develop and bring products on the market more quickly. At the same time, the new manufacturing method helps push the boundaries of current product design. New component designs, for example, mean less fuel is needed to produce the same amount of energy - a key contribution to decarbonising our planet. In addition, additive manufacturing optimises cash flow, as additive parts can be manufactured on demand, thus helping to reduce inventory.
The TruPrint 5000 3D printer is a perfect fit for Siemens Energy's industry requirements. With the 500 °C preheating option, even the demanding high-temperature alloys used in the manufacture of gas turbines can be processed in a reproducible manner. The hot build cylinder with printed component is removed from the machine and placed in the inert cooling station; the machine simply continues working on the next job in the meantime. After cooling, the component is depowdered in the depowdering station; the remaining powder can then be sieved again under shielding gas. This decoupling of parts and material handling, based on the interchangeable cylinders, means that manufacture is not only cost-effective and efficient, but also conserves resources at the same time. Siemens Energy and TRUMPF have shown how the TruPrint 5000 can be integrated in an industrial 3D printing process chain for high-temperature alloys – including digital data linking out of the office and back, performed by the machine.
