Abstract Scope |
Droplet-on-Demand additive manufacturing (DODAM) techniques have the ability to produce high resolution near-net-shaped parts which require minimal post-processing. A key requirement to ensure efficient and consistent ejection of droplets through the nozzle of a DODAM nozzle is to tune wetting behavior of the liquid metal with the body and orifices. Wetting of liquid metals is highly dependent on the compatibility with nozzle materials, influenced by various operational conditions such as the nozzle temperature, atmospheric composition, reactivity of liquid metal and nozzle etc. This work presents a screening approach to build a materials compatibility library that enables the DODAM community to understand the wetting conditions of various material combinations under precisely controlled operating conditions to support material selection for nozzle materials to maximize the jetting efficacy of materials. Results of compatibility studies for tin, aluminum, and copper will be presented, and their implications discussed.
