Z-Polymers
Z-Polymers is a Lowell, Massachusetts materials science company that emerged from the UMass Lowell Innovation Hub to build Tullomer, a PFAS-free liquid crystal super-polymer spun into ultra-fine fibers and 3D-printing filament. Founded in 2021 by materials scientist Dr. Michael Zimmerman, the company claims strength up to four times that of PEEK - and up to six times stronger than steel at a sixth of the weight - while printing on desktop machines without annealing. Its materials target aerospace, defense, medical devices, energy, and functional fabrics, and in 2026 it secured a strategic seed investment and joint development agreement with Japan's Kureha Corporation.

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.
