The article is devoted to the development of 3D printing technology for metal products based on the Fused Deposition Modelling (FDM) method. The aim of the research is the creation and testing of a prototype extrusion system for working with metal wire. Based on thermodynamic calculations accounting for specific melting energy and heat losses, a specialized heating block was designed, capable of transforming aluminium into a liquid phase. The device design was implemented by upgrading a consumer-grade FDM printer: a high-temperature extruder, a temperature control system, and a heat-resistant build platform were installed.Physical experiments with aluminium wire confirmed the fundamental possibility of extruding liquid metal and forming material layer by layer. For the further development of the technology, key improvement directions are proposed, including implementing printing in an inert gas environment and ensuring a uniform thermal regime in the build zone. The work demonstrates the potential of the FDM method for creating economically accessible metal additive manufacturing systems.
