Nanoscale Racing Car 3D Printed Within Minutes

A Formula One-style racing car just four times the width of a human hair has been created in just four minutes and 8 seconds thanks to a world record-breaking high-precision 3D printing technique. Developed by Jan Torgersen and colleagues from the Vienna University of Technology, the technology is capable of building such supremely detailed, intricate models at an all-impressive speed of 5 m/s.
