Thanks to the production of sand molds and cores without tools, you can make your manufacturing from single parts to small series in an economical way. Unlike traditional production methods, the complexity of your molds and cores has almost no importance in 3D printing. You can easily produce complex geometries with 3D printers.
The advantages of 3D printing are particularly pronounced in situations such as sand core manufacturing for turbine wheels. In the traditional production method, the individual core parts of the turbine blades must be mounted to the core in a hard way. In 3D printing, the entire turbine core can be produced in one piece. This significantly shortens the entire production process since the core assembly step is eliminated. Thus, up to 75% savings can be achieved in series with fewer quantities.
