BTW if you wonder who is this guy:<p>Dan Gelbart is a German-born, Israel-raised, and since 1973, Canada-based inventor, engineer, and entrepreneur known for his influential work in prototyping, machining, and high-tech innovation. He holds a Bachelor’s and Master’s degree in electrical engineering from the Technion-Israel Institute of Technology, where he also served as an infantry soldier during the 1967 Six Day War.<p>After moving to Canada, Gelbart began his career at MacDonald, Dettwiler and Associates (MDA), where he developed high-speed film recorders for satellite imagery and contributed to the founding of spin-off companies like MDI-Motorola and Cymbolic Sciences. He is best known as the co-founder and Chief Technology Officer of Creo Products, a British Columbia-based company specializing in laser-based printing technology. Creo grew to employ around 4,000 people and was sold to Kodak in 2005 for $1 billion, with much of its award-winning technology invented by Gelbart himself.<p>Gelbart is credited with over 100 U.S. patents (some sources state 145), spanning fields from optics and telecommunications to medical devices and metal 3D printing. He is recognized as a pioneer in computer-to-plate printing technology and has twice received the British Columbia Science Council Gold Medal. In recent years, Gelbart founded Rapidia, a Canadian manufacturer of metal 3D printing systems, introducing a water-based metal printing process that simplifies and accelerates production.
