Fast-as-lightning 3D microprinting with two lasers

"blue laser diodes project images into liquid resin using high-resolution display... high frame rate... red laser formed into thin light sheet beam and crosses blue beam vertically... micrometer-sized parts in hundred milliseconds... With more sensitive resins, we could even use LEDs instead of lasers in our 3D printer," says Professor Martin Wegener of APH. "Ultimately, we want to print 3D structures that are centimeters in size, while maintaining micrometer resolution and high printing speeds"
