Effect of binder type on properties of molding sands dedicated to 3D 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 ECIG 2025 European Cast Iron Group Meeting 2025 on 29 April 2025 in Milan presented the influence of binder type on the properties of molding sands, including sands dedicated to 3D printing. The authorsdemonstrated the possibility of replacing environmentally harmful organic binders with inorganic binders. Various technologies for binding molding compounds were presented, including chemical, thermal (also microwave) or combined binding. The effects of different binders on the strength, permeability, abrasion of the tested sands were presented, as well as their influence on the kinetics of binding or thermal deformation.
