Innovative internal application for HP metal jet 3D printing solution

Abstract

Metal Jet 3D printing has gained attention as an advanced manufacturing technique capable of producing complex metal components with high precision. This study aims to develop a successful use case of HP Metal Jet printing technology, which covers part design, mechanical properties and surface characteristics of 3D-printed 17-4PH stainless steel, comparing them with conventional manufacturing benchmarks. Key aspects examined include roughness, hardness, and tensile strength to assess the feasibility of this technology for industrial applications. The findings highlight both the advantages and limitations of Metal Jet 3D printing. While surface roughness remains an area for optimization, the process offers significant advantages, including design flexibility, material efficiency, and streamlined production workflows. With appropriate post-processing techniques, the technology can achieve even greater performance, making it a strong contender for industrial adoption. This research contributes to the growing body of knowledge on metal additive manufacturing and provides insights for future improvements in print quality, mechanical reliability, and industrial adoption.
