Effect of binder type on properties of molding sands dedicated to 3D printing
(2025) Major-Gabryś, Katarzyna; Halejcio, Dawid
Wydział Odlewnictwa
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.

Wydział Odlewnictwa
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) aimed analyzing modern solutions for molding sands, both with organic and inorganic binders. In molding sands with organic binders, the innovative approach of replacing part of the binder with biodegradable additives reduces the harmfulness of molding sand at the stage of casting production a solution, molding sands with organic binders based on modified with furfuryl alcohol resins cured by hardeners with reduced sulfur content, molding technologies with alkyd resins hardened by catalyst based on isocyanates and alkaline phenolic resin hardened by esters. Molding sands with environmentally friendly inorganic binders based on sodium silicates and aluminosilicates were also analyzed.

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.

Self-assembling, antibacterial hybrid calcium phosphate-based composites
Czechowska, Joanna P.; Pańtak, Piotr; Belcarz, Anna; Kowalska, Kinga J.; Zima, Aneta
Wydział Inżynierii Materiałowej i Ceramiki
Self-assembling materials have emerged as a groundbreaking solution in tissue engineering, offering innovative strategies to combat bacterial infections. Special attention is given to the hybrid granules. Our research focuses on self-assembling, antibacterial hybrid granules composed of hydroxyapatite, methylcellulose, and/or chitosan. These granules were produced via modified wet-chemical method and enriched with ions or nanoparticles (Cu 2+ , CuONPs). The chemical and phase compositions (XRF, XRD, FT-IR, Raman), compressive strength, thermal properties and microstructure were analyzed. Additionally, their bioactivity in simulated body fluid and antibacterial effectiveness against E. coli and S. aureus were tested. The obtained results are particularly promising as hybrids showed high mechanical strength, biocompatibility and antibacterial properties. Granules may be applied independently or as components of innovative biocomposites.

This work, presented during the V International Conference of Casting and Materials Engineering ICCME 25 in Krakow, Poland on October 27-28, 2025, describes the research on molding sands for molds and cores 3D printing. The work concerns the influence of furfuryl resin type (classical and designed for 3D printing) on cast iron castings properties. The pouring parameters were elaborated on the basis of MAGMA software. The microscopic observations of castings, produced in classical and 3D printed molds were conducted as well as roughness of the samples assessment.

The project is being realized in cooperation between AGH Faculty of Foundry Engineering (Leader), CNR-ICMATE and Aalto University School of Engineering. This work, presented during the V International Conference of Casting and Materials Engineering ICCME 25 in Krakow, Poland on October 27-28, 2025, describes the research connected with the development of molding compounds for thin-walled castings. Two compounds with organic binders and two compounds with inorganic binders of self-curing molding sands were tested. Tests were carried out on the tensile and bending strength, permeability, and friability of the compounds. For selected molding sands, tests were carried out on their thermophysical properties (hot distortion parameter), gas emission, and thermal degradation. For castings production also molds produced using additive manufacturing (3D printing technology) were used.
