In this episode of the 3DPOD, we talk with Zach Detweiler, vice president of Technology at Velo3D (NYSE: VLD), about his past as a chemist and the path that took him to his current position. We also go through the complex systems that intertwine to form a metal powder bed fusion system, including the variables that need to be controlled and what must be done in order to achieve industrial manufacturing of 3D printed parts.
