While magnesium (Mg) is a promising material for personalized temporary implants, the lack of digital manufacturing solution Mg implants impedes its potential progress. This study introduces hybrid process that integrates binder jet additive with automated dry post-machining to enable end-to-end implants. Spherical cap-shaped were additively manufactured through jetting. These placed on graphite flakes during sintering as non-reactive support material, allowing unrestricted shrinkage 15.2 % relative density 87 %. Microstructural and dimensional analysis revealed consistent interconnected porous microstructures distortion within ± 0.2 mm original drawing. High-speed milling sintered samples, assessed via an orthogonal cutting test, identified optimized parameters. A three-step machining 5-axis machining, along clamping strategies, referencing, adaptive plug-in, successfully implemented. The binder-jet printed resulted in average roughness < 1.3 µm no defects.
