Abstract Scope |
Metal additive manufacturing via liquid metal droplet jetting has a range of potential advantages that include use of non-powder feedstock materials (ingot, rod, wire), the potential to fabricate non-weldable alloys, and high material deposition rates with fine feature resolution compared with other high-rate metal AM processes. Typical droplet jetting frequencies for the two commercially available LMJ systems are in the 300-450 Hz range. Inkjet document printers, on the other hand, routinely jet at frequencies in excess of 3 kHz. This talk will present results of multi-physics simulation modeling whose aim is to optimize both ejection chamber geometry and jetting waveforms to allow higher frequency jetting. Simulation results together with experimental validation using a piezo-actuated LMJ test fixture will be presented. |
