greg-bio-picGreg Pugh, CTO

Greg Pugh started working with clay and technology at an early age. Pugh grew up in a house where the traditions of crafting things by hand are a daily function. His mother was a craft artist in West Virgina, and his father is a landscape architect that still drafts everything by hand. Pugh’s mother purchased their first computer when he was 7. It was an Apple 2gs. There was an instant bond between Pugh and the computer. Pugh began to take his studies in clay seriously during high school. Pugh was a community member at the Urban Institute for Contemporary Arts in Grand Rapids, Michigan. This experience helped set up Pugh to continue his education in ceramics. To further his ceramic studies, he went to Bowling Green State University, and studied under John Balistreri, head of the ceramics program and known for wood-fired ceramics. His initial intention was to become a wood-fired potter, however, that quickly changed when Pugh became involved in Balistreri’s 3D printing project in the spring of 2007. Pugh became involved in the research and he became a driving force in the development of the project. Pugh is currently the Director of Technical Operations for Tethon 3D in Omaha, Nebraska. He has helped develop many materials for 3D printing. Pugh’s driving force to develop new ceramic materials is to answer a very basic question. “What can clay do?”
