Polymer Damage Detector

New Polymer Additive Reveals Microscopic Damage

A new polymer additive will allow engineers to detect damage to steel long before a visual examination would reveal deterioration. The creators imbed tiny capsules of uv sensitive dye into a polymer, when the base material is damaged the capsules release the dye allowing engineers to detect microscopic damage. This will be especially helpful for systems where microscopic damage can quickly have massive ramifications. Read more here.

Video: MX3D’S Intriguing 3D Printer

We posted an article back in October about Dutch company MX3D’s plan to robotically 3D print a bridge over a canal in Amsterdam. Well a video has surface showing their robotic 3D printers in action and it is incredible. The system uses a 6-axis robot arm to squirt molten steel, through a nozzle that welds it as it comes out. Watch the video below and enjoy!

Structural Steel Welder

New Remote Control Welding Technology is Improving Efficiency

New remote control technology is giving the welder much more control of the weld settings while at the weld joint. This is proving to be highly beneficial for welding when there is considerable distance between the joint and power source. Traditionally, remote controls required an additional cord running to the power source to control voltage, these are more costly to buy, manage and repair. Wireless is also an option but it leaves the welder no way to adjust the voltage without walking […]

New Metal is 100X Lighter than Styromfoam

HRL Laboratories in Malibu, California has developed a new material they’re calling “microlattice.” It is made up of tiny interconnected hollow tubes that mimics the structure of bridge supports. By adjusting the chemical makeup up microlattice they can adjust the its rigidity to either be highly flexible to absorb shock or exceptionally rigid for structural support.Read more here.

Hydrogen Embrittlement

Researchers are trying to Find Out Why Hydrogen Makes Steel Brittle

Engineers have long known that hydrogen makes steel brittle but no one has yet figured out why the weakening occurs. While stronger and lighter steel continues to become available, steel’s one remaining weakness, called hydrogen embrittlement, holds it back from mainstream use. Oxford University researchers are now collaborating to try to sove this mystery once and for all. Read more here.

Big River Steel Under Construction

Big River Steel Mill Projected to have 3 Billion Dollar Impact on the Local Economy

In what is being called the biggest economic development project in Arkansas history, it is being estimated that the Big River Steel Mill will have a 3 billion dollar impact on the local economy. Big River Steel has moved 1.2 million cubic yards of soil and installed 22,000 tons of rebar so far in the massive project. The space under the roof of the finishing mill facility is roughly 747,000 square feet or the equivalent of 16 football fields. Nu […]
