The foundry allows the economic production of large quantities of dimensionally similar construction parts with adjustable properties. Due to the development pressure that the foundry is exposed to due to the advent of additive manufacturing, it leads to development needs in lightweight construction, functional integration, material efficiency and resource conservation [Ing15]. This increases the demands placed on temperature-resistant casting molds and cores [Wös19] with regard to thermal shock and low thermal expansion, high thermal conductivity and corrosion resistance [Pfe01].
