Foundry cores are an essential part of the production of turbine blades for aviation, aero derivative and land based gas turbines. The internal cooling structure of the turbine blade facilitates a reduction in the substrate temperature, creating opportunities to lower fuel consumption, improve turbine efficiency and decrease engine emissions. The need for complex core design has increased dramatically with customers’ demands for smaller, more efficient and cost-effective engines running at higher temperatures, stretching existing alloy technology to its limit.
These new complex core designs can prove to be difficult to produce using traditional methods due to the web of internal passageways and chambers present to promote the increased surface area and airflow to cool the blade.
What kind of impact can the distributive technology of 3D ceramic printing have on foundry core production in the future?
