How to 3D print a bicycle bridge? Study discusses Dutch concrete printing project

IMG_8618

In 2017, the world’s first prestressed 3D printed concrete bicycle bridge officially opened to cyclists. It was created by the Eindhoven University of Technology (TU/e) in collaboration with construction company BAM Infra, and was installed in the Dutch village of Gemert. The bridge was part of a research project that involved the development of a giant concrete 3D printer, and now the researchers involved have published a paper on the project, entitled “3D Printed Concrete Bridge.”

The bridge was designed to replace an existing structure over a small local canal. The structure is 3.5 meters wide and spans 6.5 meters. It consists of 3D printed elements that are rotated 90 degrees after printing, then pressed together by post-tensioned prestressing tendons.

New “Super Wood” is as strong as steel

IMG_8569

Wood is great. It looks nice as a building material. It grows right out of the ground. But compared to things like concrete, marble, and steel, it’s not all that strong. Well, it didn’t used to be, anyway. Scientists have now created a “super wood” that’s strong enough to stop a bullet.

Here’s what NASA thinks Mars houses could look like

IMG_8054

They’ve awarded cash prizes as part of an ongoing competition.

NASA has selected five winners in an ongoing contest it has been running to get smart ideas about how to build a 3d-printed habitat on Mars.

The winners have passed level one of the 3D-Printed Habitat Centennial Challenge, which required developing about 60 percent of the design. Level Two will require greater complexity with 100 percent completion and an understanding of the hydraulics of each build. The teams will then create virtual structures and, on April 29, build them for real on the campus of Bradley University in Peoria, Ill.

The teams have different approaches and their video entries reflect that. First-place Team Zopherus, for example, highlights the autonomous robots that build out their modular structures. Using the Martian soil, their robots would build structures from the ground up.

Wellness real estate has blossomed into a $134 billion industry worldwide- and it’s growing fast

IMG_7583

From personalized wellness programs to fitness-focused apps, luxury homes are focusing on making residents feel better

It’s the non-stop pace of our digital lives. An increasingly isolated and aging population. Rising chronic illness. Climate change. Given the pressures of the modern world, a gym membership and taking the occasional “mental health day” often just aren’t enough to maintain a healthy lifestyle.

One way to achieve optimum wellness, experts and developers say, is by choosing a home that is designed for it.

Virgin Voyages hope to appeal to virgin cruisers with its new line

IMG_7185

Race you to the “catamaran net.”

The designers behind the world’s newest cruise ship have never been on a cruise. But if this approach seems crazy, well, it’s all strategy. The group, dubbed the “Creative Collective” and led by the likes of Roman and Williams (The Boom Boom Room, Le Coucou, Ace Hotels), Concrete Amsterdam (citizenM hotels, W London), and Tom Dixon’s Design Research Studio (Shoreditch House, Mondrian Hotels), are deep into designing Virgin’s cruise line with the aim of attracting travelers who normally wouldn’t touch the idea of taking a cruise with a ten foot pole. In fact, Rob Wagemans of Concrete Amsterdam joined the project under the condition that he wouldn’t have to go on any existing cruises at all.

Designed for a community of tech elites, these tiny homes are 3D printed, run by Tesla batteries, and cost $250,000

IMG_7093

A 609-acre California coastal community, Walden Monterey, serves as a respite for those needing to recharge their batteries — especially the region’s leaders in tech.

The enclave’s founder, Nick Jekogian, invites potential homeowners to visit the property and stay in portable homes, called “roving rooms,” to truly experience the sustainable, outdoor-centric lifestyle the community has to offer.

Now, a new unit, called the Galini Sleeping Pod, will be used to house prospective buyers as they consider making a more permanent purchase of the land.

Pipe dreams: can ‘nano apartments’ solve Hong Kong’s housing crisis?

IMG_7051

The city with the world’s tiniest and costliest living spaces may soon convert drainpipes into homes. The aim is to get young people on the property ladder – but how small is too small?

“Both indoors and out, life in Hong Kong can feel pretty suffocating at times,” says 39-year-old finance worker Wai Li, who rents a 200 sq ft (19 sq m) “nano flat” by herself in Hong Kong’s Sheung Wan neighbourhood. Li’s living area is little more than the size of two standard Hong Kong parking spaces.

These Uber Air ‘Skyport’ concepts look straight out of Star Wars

IMG_6822

If Uber is to get its “flying taxi” service off the ground, it will need dozens of launchpads and landing sites on rooftops around cities as a supportive infrastructure. At the ride-hailing company’s second annual Elevate conference in Los Angeles, six architecture firms presented their winning designs of what these so-called “Skyports” could look like. And holy cow, these things look straight out of Star Wars.

American highways are so expensive that cities are tearing them down — here’s what they’re turning into

Throughout the 20th century, highways were key generators of economic growth for American cities. They allowed commuters to quickly travel between urban centers and the suburbs, unclogged traffic-ridden streets, and created infrastructure jobs.

But these days, investing in highways is a bad business decision for many cities.

An increasing number of cities around the US are choosing to tear down or transform parts of their dilapidated interstates, rather than repair them. These redevelopments are largely happening because old highways are costly to rebuild, according to Rob Steuteville from a DC-based nonprofit called the Congress for New Urbanism.

For the past decade, Steuteville’s team has documented cities that have or are considering highway removals. He expects the trend to continue to grow.

Floating city of modular, eco-friendly pyramids is now enrolling citizens

IMG_6677

Pierpaolo Lazzarini envisions wayaland, a floating city made of modular pyramids that offers different living and entertainment facilities including hotels, shops, spas, gyms, bars and cinemas. completed with solar panels and water turbines for energy supply, the project aims to provide a new offshore living experience within a self-sustainable community.

The main waya pyramid comprises different modules that overlap on a floating 54 by 54-meter basement, offering a total surface of about 3000 m2. The basement includes a large entrance for boats and a reception, while the part of each module submerged underwater stores engines, equipment, additional energy sources and generators. dividing the height in ten different floors with a total surface of 6500 m2, the complete waya reaches a maximum height of 30 meters from the waterline.

This new 3D-printed house was built by a portable robot in just 48 hours

IMG_6533

There are a lot of 3D-printed houses popping up these days, but this is the first time an architect with the renown of Massimiliano Locatelli of CLS Architetti and Arup has tackled one. Built out of a special quick-drying mortar, the 1,076-square-foot house was constructed in just 48 hours. Locatelli envisions 3D printing as the housing of the future – and that his house could be constructed anywhere,”even the moon.”

The world’s first 3D-printed steel bridge looks like it came from another planet

IMG_6251

Dutch technology company MX3D just officially unveiled the world’s first 3D-printed stainless steel bridge. It took four robots, nearly 10,000 pounds of stainless steel, about 684 miles of wire, and six months of printing to build the sinuous, undulating structure, which looks like it’s straight out of a science-fiction movie.

The MX3D Bridge, designed by Joris Laarman Lab, is around 41 feet by 20 feet, and it’s made from a new kind of steel. 3D-printing created a ribbed surface as robots added layers upon layers; Gizmodo said it could be buffed out, but MX3D plans to keep the unique, rough look.
