low-cost replication techniques that will make the fuze application affordable.
That's where Amish Desai (who used to work for Liquidmetal) comes into the picture. He, through Tanner Research, has won at least a couple of SBIR awards in order to develop manufacturing techniques for these bulk metallic glass applications:
Mass Fabricating S&A with Bulk Metallic Glass: Micro-Components with Nano-scale…
A state of the art technology suitable for facilitating the mass fabrication of metallic components used in high g gun-launched MEMS-based S&A devices is Bulk Metallic Glass (BMG). The emerging need for micro-scale S&A devices to complement the smart fuzing in modern munitions is jeopardized by high implementation cost of the metallic components able to survive the harsh gun-launch environment. The impact of cost reduction and/or cost avoidance on implementing critical munitions' designs actually starts with the S&A device. Tanner Research proposes to design and implement a mass fabrication production process for micro-scale bulk metallic glass (BMG) components with nano-scale tolerances. This production capability, when implemented in Phase II, will be similar to other MEMS-based processes implemented by Tanner, and used to support MEMS-based S&A device fabrication.
Mass Fabricating S&A with Bulk Metallic Glass: Micro-Components with Nano-scale…
In Phase I Tanner Research has already demonstrated a state of the art technology suitable for facilitating the mass fabrication of metallic components used in high g gun-launched MEMS-based S&A devices. The emerging need for micro-scale S&A devices to complement the smart fuzing in modern munitions is jeopardized by high implementation cost of the metallic components able to survive the harsh gun-launch environment. The impact of cost reduction and/or cost avoidance on implementing critical munitions' designs actually starts with the S&A device. Tanner Research is proposing as a primary objective to further develop and refine the micro to nano scale manufacturing techniques required to establish a process for extremely high-rate, low-cost manufacture of micro-scale components needed for use in the Army's MEMS safe and arm device. We envision the Phase II program to be an opportunity to develop a batch scale forming process to mass fabricate metallic sliders and parts.
