The Open Source RepRap Simpson 3D Printer Design Reduces Friction, Uses Less “Vitamins”

John Biggs

This is the Grounded Experimental Delta 3D printer aka the Simpson, a project built by computer science teacher Nicholas Seward that does away with the excess frames, pulleys, and hardware associated with earlier models. Seward wanted a machine that could print itself and used "less vitamins," namely metal parts that the machine couldn't create from scratch. There are still motors and controllers, but there are fewer in this model than in any other I've seen.

3D Printing Tiny Batteries For Tiny Robots, Medical Devices

Jennifer Hicks, Contributor

Researchers from Harvard's School of Engineering and Applied Science and University of Illinois at Urbana-Champaign were able to 3D print lithium-ion microbatteries - the size of a grain of sand. This will have a tremendous impact on the advancement of tiny devices in the field of robotics, medicine and communications.

How to print tiny batteries

Thomas Anderson

3D printing can now be used to print lithium-ion microbatteries the size of a grain of sand. The printed microbatteries could supply electricity to tiny devices in fields from medicine to communications, including many that have lingered on lab benches for lack of a battery small enough to fit the device, yet provide enough stored energy to power them.
