Mike Zimmerman is the founder and CEO of Z-Polymers, the Lowell, Massachusetts company behind Tullomer, a melt-spun super polymer marketed as stronger than PEEK and stainless steel yet light enough to print on a desktop 3D machine. A career materials scientist with a PhD in mechanical engineering, he spent nearly 15 years at Bell Labs and Saint-Gobain before founding a string of deep-tech ventures including Quantum Leap Packaging and the solid-state battery company Ionic Materials. He has also taught materials science at Tufts University for more than three decades.
Mark Sommer is the founder and CEO of Gamma Alloys, a Santa Clarita-based materials company that 'decorates' metal powders with ceramic nanoparticles to make aluminum strong enough to 3D print into aerospace and automotive parts. He simultaneously leads Del West Engineering, the Formula 1 world's go-to maker of titanium valves and lightweight valvetrain components. Backed by Boeing HorizonX, his bet is that of the roughly 5,500 industrial alloys in use, only a few dozen work with 3D printers today, and Gamma's nano-ceramic process can unlock the rest.
