Laser Cutter vs. 3D Printer

At a recent conference, Jim Merrel mentioned that he bought a laser cutter rather than a 3D printer for his STEM lab at LabRats in San Diego. When asked why, he responded you can produce things faster on a laser cutter. Laser cutters can reduce “print times” to minutes, not hours.

Here are some resources to give you an idea of what a laser cutter can do and how to use it.
