A novel method for metal additive manufacturing
Current metal additive manufacturing processes either use a high-power heat energy source to melt and fuse material or they use post-processing steps like sintering or machining to give the material its net shape and/or structural integrity. We are developing a fundamentally new method of additive manufacturing that does not use a high-power heat energy source or any post-processing operation.
I have had the opportunity to be involved in this project since its inception. The project has demanded multi-disciplinary approach that includes:
Material science and microscopy oriented research to understand the process physics.
Mechanical engineering and design to develop prototype systems.
Electronic hardware and software development.
Process engineering that ensures reliably functioning systems and enables continuous improvement of existing processes and systems.
