The first 3D-printed steelbridge in Europe

The 3D-printed pedestrian bridge in Amsterdam's Red Light District.

Following several years of planning and research, the world's first 3D printed footbridge is open to the public in Europe.

 

The 12 m bridge was built by Dutch company MX3D and is serving as a "living laboratory" in Amsterdam's city center.

Researchers and engineers at Imperial College London were able to 3D-print the bridge — which now serves pedestrians and cyclists crossing Amsterdam's Oudezijds Achterburgwal canal.

"A 3D-printed metal structure large and strong enough to handle pedestrian traffic has never been constructed before," said Imperial College London professor Leroy Gardner in a news release.

Designers first created the concept for the bridge in 2015, with the goal of making an "exceptionally efficient structure," emphasizing both simplicity and safety.

 

"We have tested and simulated the structure and its components throughout the printing process and upon its completion, and it's fantastic to see it finally open to the public," Gardner said.

Researchers at Imperial College London are collecting data in real-time to monitor how it behaves with foot and cyclist traffic.

"Research into this new technology for the construction industry has huge potential for the future," said Imperial College London co-contributor Dr. Craig Buchanan. "It is fascinating and we are delighted that the structure is used."

A French climber’s reward on Mont Blanc

 

With a summit of 4,809m, Mont Blanc is the highest mountain in the Alps and in Western Europe.

The mountain is located in the French Alps, very close to the border with Italy.

Mont Blanc is “owned” by both France and Italy under a bilateral agreement. The lowest recorded temperature on Mont Blanc is -43°C, set in January 1893.

More than 20,000 climbers reach the summit of the mountain every year.

In 2013, a French mountain climber ascending Mont Blanc found something besides stunning views: a box containing about $340,000 worth of precious stones.

The gems—an assortment of emeralds, sapphires, and rubies—are believed to have been on an Air India flight that crashed on the mountain in 1966.

All 117 passengers and crew members were killed in the crash of the Kanchenjanga, a plane named, somewhat ironically, for the world’s third-highest mountain.

The plane was bound to New York from Mumbai and crashed on its way to Geneva from Beirut. Among the passengers was Homi Jehangir Bhabha, a physicist regarded as the father of India’s nuclear program, which gave rise to conspiracy theories about the crash

Due to global warming Mont Blanc’s Bosson glacier is receding, which has exposed more of the wreckage from the  crash.

The climber handed over the gems to the authorities, as required by French law. After efforts to find the rightful owners of the gems were unsuccessful, the unnamed climber  was rewarded with half of them. The government in Chamonix, France, will retain the other half.

The discovery of precious cargo from a mountain plane crash is unusual but not unheard of. In the US, a small plane loaded with 6,000 pounds of marijuana crashed in California’s Sierra Nevada mountains above Yosemite National park in 1976, supplying enterprising climbers with free weed for years.
