Design and Development of a Metal Jet Print-Head

Additive manufacturing or 3D printing is a novel and fast-evolving technology in the manufacturing industry. Fused Deposition Modeling is a widely used 3D printing technology that produces objects by continuously extruding melted filament and adding it layer by layer onto the substrate. This method allows for more flexibility in the design of the parts and their structural complexity. The majority of FDM printers use plastic filaments since it is very challenging to print with metals. This research work focuses on the design and development of a metal jet print head for the FDM printer which can melt and extrude metal filaments and build metal parts. This study gives an idea about developing a high-temperature metal jet print-head that can print aluminium metal using less power consumption and less time. Additionally, factors including the heating method, target temperature, heating time, consumed electrical power, and materials required for the development of the print-head are discussed.
