EP. 006 - Marvin Groeb

Winston and Eddie are joined by fellow instamachinist Marvin Groeb (@marvgro on IG) on DFX episode 6. Learn how Marvin combines his formal material scientist education along with a tinkerer's talent for CNC machining to push the limits of surface finish quality in his role at Kern Microtechnik. Hear about how one of the world's highest precision CNC milling machines is designed. And we discuss Marvin's experience with building the ultimate DIY 3d printer, the maker scene in Germany and why less is sometimes more when it comes to single flute end mills. In a brief shop update we discover that Winston will soon be IMTS-bound while Eddie cleans up the dust after some minor workshop remodeling.
