Selection of chemically cured molding sands’ with inorganic binders dedicated to 3D sand printing

Abstract

This conference abstract shows the results achieved within NetCastPL4.0 project. The project is being realized in cooperation between AGH Faculty of Foundry Engineering (Leader), CNR-ICMATE and Aalto University School of Engineering. The work presented during XXXI. medzinárodnej vedeckej konferencie slovenských, českých a poľských zlievačov SPOLUPRACA 2025 in Rajecke Teplice (Slovak Republik) determined the influence of molding sands’ with different inorganic binders composition on their chosen properties. The molding sands with 3 commercial inorganic binders used in traditional mold and core production technologies were tested as well as the molding sands dedicated to 3D printing with new binders based on them. Four types of hardener were used for chemical curing.
