Secure 3D Printing: 'Three-Layer' System Protects Parts from Hackers

A 3D printer is essentially a small embedded computer — and can be exploited like one.

Researchers from Georgia Institute of Technology and Rutgers University have developed a “three-layer” way of certifying that an additively manufactured part has not been compromised.

Sound-Off: How Does ‘Cold Forming’ Impact a Part?

The manufacturing process of "cold forming" applies force to a metal as it is staged in a die. The technology, used originally in the early 1900s to create artillery shells, supports the creation of a variety of sophisticated, small parts, including fasteners, pins, and screws. But how do the residual stresses caused by the process affect the life of the part?

Electromagnetic Actuator Decouples Linear and Rotary Motions

A lightweight module for rapid, accurate, and versatile positioning of semiconductor chips features a novel electromechanical actuator that can move objects both linearly and rotationally. The technology was developed by researchers at the A*STAR Singapore Institute of Manufacturing Technology (A*STAR SIMTech) and National University of Singapore (SIMTech-NUS) Joint Lab.

3D Printed Tensegrity Object Can Change Shape

A team of researchers from the Georgia Institute of Technology has developed a way to use 3D printers to create objects capable of shape change. The objects use tensegrity, a structural system of floating rods in compression and cables in continuous tension. The researchers fabricated the struts from shape memory polymers that unfold when heated. The technology could someday be used in applications ranging from space missions to biomedical devices.

How Metal 3D Printing is Redefining Part Design

It's one of the basic rules of manufacturing: As part complexity increases, so do machining and assembly costs. But what if there were a different way to produce metal parts — one with fewer limitations than traditional milling, turning, and grinding processes, and able to build complex parts in less time and with little human intervention?

3D-Printed Soft Robot ‘Walks’ on Any Terrain

Traditional robots often feature isolated mechanical joints. These discrete components limit a rover’s ability to traverse sand, stone, and other challenging environments.

A team at the University of California San Diego has demonstrated a more flexible option: a soft robot that lifts its legs over obstacles and operates on a variety of terrains. The 3D-printed quadrupedal technology may someday support search-and-rescue missions requiring intelligent navigation capabilities.

What's New on Tech Briefs: Brickmaking on Mars a 'Smashing' Success

With support from Congress and the President, NASA aims to send a manned mission to Mars by 2040. Establishing a human presence on the Red Planet, however, will require permanent shelters.

And lugging a pile of bricks on the nine-month, 35-million-mile trip is out of the question.
