For those unfamiliar with microprinting, it is typically done red lasers with wavelengths between 700 and 800 nanometers. These are called femtosecond lasers, said Philippe Paliard, cofounder at Microlight3D, and they are very big, expensive, and difficult to handle, with maintenance needed regularly. According to Paliard, some scientists believe that these are the only lasers that can be used in 3D microprinting.
Looking at the Falcon, printed by Paliard with green lasers, we now have an example that shows us that 3D microprinting is not limited to red lasers. And in case you had any doubt, Paliard also printed a teeny tiny Baby Yoda (that baby) and some pretty cool itsy bitsy X-wings.
