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.

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.

A New Material for Mars Habitats? Mars Itself

Researchers from the University of California, San Diego demonstrated a compaction technique that may someday be used to turn Mars soil into building blocks for the Red Planet. The scientists' new method of applying pressure offers construction possibilities as NASA plans manned Mars missions in the upcoming decades.

What's New on TechBriefs.com: 3D Printing's Next Frontier

In 1983, when Chuck Hull was spending nights and weekends building the first 3D printer, he couldn’t have imagined that someone would eventually use the apparatus to build a toaster from ashes.

How 3D Printing Began, Layer by Layer

In 1983, Chuck Hull worked for a small California-based company that used ultraviolet light to turn liquid polymers into hardened, or cured, coatings. Inside the firm’s lab on his nights and weekends, Hull found a way to make UV-curable materials the basis for his Stereolithography Apparatus, patented the following year.

Tech Briefs spoke with Hull about the future of his invention, the 3D printer.
