The second episode provides an in-depth exchange between Olaf Diegel, associate consultant and design expert, and Terry Wohlers, founder and president, both of Wohlers Associates. They discuss basic and advanced approaches, tools, and solutions used to design for additive manufacturing, also referred to as DfAM. Olaf has designed and manufactured more than 100 commercial products and is perhaps best known for his innovative 3D-printed guitars.
