3D Printed Optics
I came across a rather interesting idea while checking out Disney's Research Hub: Printed Optics. They seem to be quite interested in fabrication and 3D printing as a good majority of their videos pertain to this type of subject matter. More interestingly, they have devised a way to print objects that embed optical characteristics so that light traverses where they intend to create some very interesting effects.

Printable Electronics
Two recent developments are getting us very close to printing electronics, one using inkjet printers to print conductive material for electronics and photonics and another, a conductive ink to create flexible electronics for books, displays and wearables.

LaserCAD Installation for the Anywells Laser Controller
How to install the LaserCAD Trocen Anywells Laser Cutter Controller and CAD software. The Software to be installed is called LaserCAD and is the software that allows communication between the computer and the laser cutter controller, but it also allows you to draw geometry, add text and images and download that file to the laser cutter controller.
