John Biehler has been writing online about technology since 1999. An avid photographer and generally curious geek, he discovered 3D printing a number of years ago and built his first 3D printer shortly thereafter. Since then, he has been actively sharing his knowledge about the technology with thousands of people at various events and conferences in Western Canada and the Pacific Northwest, on television and radio, as well as online through his website. He cofounded a Vancouver-area group of 3D printer builders and enthusiasts that has grown exponentially since it started and as the technology heads toward the mainstream.
