With her mastery of 3D printing, Janet Lieberman helped create the first successful hands-free couples’ vibrator in 2014. Lieberman earned a BS from MIT in mechanical engineering in 2007 and immediately went to work designing 3D printers for Z Corporation, MindsInSync, and industry leader Makerbot, where she was the lead engineer for the award-winning Mini Compact Desktop 3D Printer. When she created Dame Industries with Alexandra Fine in 2014, Lieberman used her knowledge of 3D printers to tinker with the design and production of prototypes for Eva, a hands-free vibrator that could be recharged via USB and that incorporated feedback from couples who tested the product. Fine and Lieberman launched an IndieGoGo campaign to fund mass production and quickly blasted past their $50,000 goal in five days, eventually earning over $800,000 from their initial campaign, along with accolades from Bustle, Daily Dot, and Forbes, among many others. Lieberman continues to fine-tune Eva’s design and work on ways to speed production of the popular toy.
