New special moulding material for cores produced by additive manufacturing

GTP Schäfer from Grevenbroich has developed the new special moulding material Cerapearl 3D. This moulding material allows cores to be produced through additive manufacturing – instead of from segments made by shooting. This makes the usually following work steps unnecessary, which means less time is required for manufacture.

Additive manufacturing is becoming increasingly important for production. This technology for production has made it feasible to reproduce geometries that continue to expand in complexity. At the same time, however, the demands made of the moulding material used by this production technology have risen.

With Cerapearl 3D, GTP SCHÄFER has developed a synthetic moulding material that satisfies the highest demands. Among its convincing qualities are its thermal resistance, high permeability for gasses, good flow behaviour, reduced need for binding agents and its suitability for additive manufacturing. The new moulding material is printable with all usual binding agents on all 3D printers commonly used on the market. Adjusting the machines is not necessary. Production of a core in one piece means there is no additional work assembling the core, and the dimensional accuracy of the cast parts increases.
