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.
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.
New 3D printing algorithms speed production, reduce waste
Purdue University researchers have developed two software algorithms for trimming time and material, reducing 3D-printing time by up to 30 percent and the amount of support material by up to 65 percent.
The new PackMerger algorithm works by printing a project in segments that can fit into the printing tray and later be glued together.
