The New 3D Dimensions^TM Powered by Braskem Design Competition provides an innovative forum for the next generation of 3D printing design leaders

Philadelphia, PA - June9, 2022 - Braskem (B3: BRKM3, BRKM5, and BRKM6; LATIBEX: XBRK; OTC: BRKMY), the largest polyolefins producer in the Americas, as well as a market leader and pioneer producer of biopolymers on an industrial scale announced today the winners for the New 3D Dimensions^TM powered by Braskem design competition.

In its inaugural year, the competition received a strong turnout from universities and colleges across the nation, and 18 teams made it to round two. An esteemed slate of judges reviewed submissions from a competitive pool of applicants who created designs based on one of two categories (1) Industrial Applications for Aerospace & Transportation and (2) Quality of Life for Mobility & Medical, with both categories aimed at aiding the development of the next generation of sustainable and innovative 3D printed designs. Braskem invited students from California Polytechnic State University, Virginia Tech, Carnegie Mellon University, and Penn State University to compete for cash prizes for best design.

"We are proud of everyone who participated in our first edition of New 3D Dimensions^TM powered by Braskem. It was great to witness the creative and inspirational designs from all the students. The students submitted innovative ideas that have the potential to set the standard for the future of 3D printing," said Mark Nikolich, CEO, Braskem America. "I'd like to congratulate our winners. We hope you continue to bring your ideas to life, and we look forward to seeing what you accomplish in the coming years."
