Building a 3D Printed Atomic-Resolution Scanning Tunneling Microscope (STM) | DIY STM Explained

The link to the GitHub repo for all design files and raw data: In this video, I share the journey of creating the world’s first fully 3D-printed Scanning Tunneling Microscope (STM) — an instrument capable of visualizing individual atoms! From designing and constructing the piezoelectric scanner to crafting atomic-sharp tungsten tips, this project pushes the boundaries of DIY science at home. Using affordable, 3D-printed parts, I tackled the technical challenges of building an STM in my living room, including how to achieve atomic resolution with just a few cents’ worth of components. Discover how I: Recreated Dan Berard’s open-source STM design and took it to the next level with 3D-printed components. Built a piezoelectric actuator capable of sub-nanometer accuracy. Crafted precision tips from tungsten wire for atomic-level scanning. Designed a vibration isolation system to stabilize the STM and achieve
