WHAT IT TAKES TO REALIZE YOUR VISIONS
Every project begins with a vision — and design goals. The materials in our palette can be used individually or combined in the same design, and even in the same layer, to satisfy your design goals for strength, hardness, corrosion resistance, conductivity, biocompatibility and more. This has enabled designers to build miniaturized mechanisms that can withstand 2,000 G’s of acceleration, run at 10,000 rpm or survive over 2,000,000 cycles of mechanical and thermal stress —all in mission-critical applications. And because they can be fabricated in highly complex structures, designers have even more options to create the small, robust, reliable devices and components that make a big difference in the world.
