| Abstract Scope |
Recent advancements in liquid metal deposition technologies have fostered innovative additive manufacturing solutions. This study introduces the MetalJet 3.0 system, a dual-head drop-on-demand (DoD) metal deposition platform, which advances upon previous MetalJet research to facilitate multi-material 3D printing in a single build process. The complex mechatronic control system combines an FPGA, integrating two independent deposition heads, an induction heater, a waveform generator, in-situ monitoring cameras, and high-precision linear stages with encoders in a LabVIEW program. The system applies Magnetohydrodynamics (MHD) to create jetting pulses and is equipped with a strobe camera to configure the jetting. This voxel-defined Drop-on-demand process has achieved an accuracy of 50um, giving it the potential to accelerate progress in materials and functional structures across industries such as microelectronics, robotics, and medical implants. Experimental evaluation using Sn in both heads asses printing accuracy and alignment. The dual-head DoD system exhibits promising potential in fabricating voxel-defined complex multi-material structures, free-standing structures and FGMs, underscoring its potential to revolutionize additive manufacturing. |
