Additive manufacturing is in addition to widespread manufacturing of functional prototypes increasingly deployed for manufacturing of components in Titanium alloys for a wide range of applications e.g. medical, dental, aerospace and industrial. Robust material properties and adhering to material standards are instrumental when moving into mass production of components.
Digital Metal® technology, a two-step Additive Manufacturing process, was applied for manufacturing of components in Ti-6Al-4V. Layer wise precision binder jetting on powder bed is followed by a curing to develop component’s green strength. Subsequently non-bonded powder is removed and component sintered to develop density and strength. Process parameters are optimized for the alloy and physical properties examined in relation to material standard ISO 22068.
Chemical composition and microstructure has been monitored as a function of process parameters. Mechanical properties investigated in the different directions relative the build direction and dimensional accuracy on components evaluated.
