Effect of Span-80 to Moisture Resistance of Near-infrared Curing 3D Printing Sodium Silicate Foundry Sands

The paper presents the results of dimensional and shape analysis of additively manufactured shaped parts of foundry moulds; specifically, shaped gate valve inserts made of DIEVAR steel used in the die-casting process of aluminium alloys. The paper aims to provide a comprehensive overview of dimensional and shape analysis during the manufacturing of shaped mould parts before their use in foundry operating conditions. The manufacturing operations include additive manufacturing, heat treatment, machining, and applying a protective coating. Based on these technological operations, the required component accuracy is achieved before application in the operating conditions. The dimensional and shape analysis was measured by 3D scanning and 3D measuring methodology on a coordinate measuring machine. The ROMER ABSOLUTE ARM 3D scanning arm and the THOME PRÄZISION coordinate measuring machine were used for the measurements. The paper presents findings in the development and application of additive manufacturing technologies in engineering metallurgy.
