Sand printing process uses conventional foundry-grade materials to digitally create moulds & cores for sand casting, without the need for a physical pattern.
Furan resins, suited for sand casting foundries, create complex sand cores and moulds directly from CAD data, eliminating the need of a physical pattern to create a core or mould. The system manufactures even the most complex cores with furan binder, giving the ability to produce castings for a wide range of applications.
