This triple gear is a real thing, and thanks to some intricate math and the advent of 3-D printing, it exists. Before this, at least as far as I can tell, a triple-meshed gear required one of the gears to turn in the opposite direction as the other two. That is no longer the case.
I can’t for the life of me imagine what this would be used in, but hey … at least we have it now. Get to designing!

How to 3-D Print the Skeleton of a Living Animal: Amazing story from Wired Science about a grad student working in an imaging lab who figured out how to take a CT scan of a rat and turn into into a 3D-printed skeleton!
I would gladly get shot with radiation if one of you would print my skull.

Printing a New Lease on Life
Just in case landing on another planet wasn’t cool enough for you today: Emma is two years old, and she was born with a rare disease called arthrogryposis. It caused her to not be able to raise her arms above her head or move and play like a normal child. Thanks to a 3-D printed exoskeleton system called WREX, she can now do that.
The best part? If a piece breaks or needs adjustment as she grows, they can print a new one in no time at all. A heartwarming application of technology.
Previously: An amazing robotic exoskeleton that can help paraplegics walk.
Now In The Print Queue: Custom Bone Implants
Within the next 10 years, dentists and orthopedists should be able to print custom bone scaffolds on 3D printers. Doctors would mold the bone scaffold on a computer, fitting it exactly to the patient’s size and anatomy, and then implant it. They would then stimulate bone growth factors, eventually the body would grow new bone around the scaffold, and the implant would dissolve away after a few years.
Here it is at work.
Really cool solar powered printer - the sand is used as ink!
I’m truly blown away by this.
A solar-powered 3D printer in an Egyptian desert creates with sand and magnified sunlight to make glass-based objects.
In a world increasingly concerned with questions of energy production and raw material shortages, this project explores the potential of desert manufacturing, where energy and material occur in abundance.
In this experiment sunlight and sand are used as raw energy and material to produce glass objects using a 3D printing process, that combines natural energy and material with high-tech production technology.
Solar-sintering aims to raise questions about the future of manufacturing and trigger dreams of the full utilisation of the production potential of the world’s most efficient energy resource - the sun. Whilst not providing definitive answers this experiment aims to provide a point of departure for fresh thinking.
Can I get a hell yeah? Also, who do you call for tech support when your computer won’t recognize that it’s connected, and it just printed fine yesterday GAHHHHHHHH!!!
