Will 3D printing solve the affordable housing crisis?
3D printing’s impact on construction is slowly materializing.
Owning one’s own house—a dream of human beings ever since Cro-Magnons looked out of their caves at the retreating glaciers—has been sometimes more, sometimes less affordable. Currently, we’re in one of the less affordable phases. With construction accounting for almost 60 percent of the cost of a new single-family home, measures that reduce labor and simplify material needs may make the dream more accessible for many.
Cue the 3D-printing evangelists. The 2010s have been ringing with the hosannas of houses extruded from a 3D printer in hours, sometimes many of them per day. The options seem limitless, with made-to-order versions in concrete, like Icon’s tiny house in Austin; ABS plastic and carbon fiber, like Branch Technology’s prototype home in Chattanooga; and recycled materials, like Chinese manufacturer WinSun’s five-story apartment building in Suzhou. By simplifying construction, we’re told, 3D printing can provide affordable shelter to everyone from the working poor to refugees.

The newest industrial revolution: How a tech unicorn’s 3-d metal printers could remake manufacturing
Ric Fulop, the 43-year-old cofounder and chief executive of Desktop Metal, is eager to show off the skunkworks for the company’s giant 3-D metal printers, which can produce stainless steel, aluminum and other metal alloy parts at assembly-line speeds and in large quantities. It’s the first time he’s taken an outsider to the facility in Nashua, New Hampshire, just across the state line from Desktop Metal’s headquarters in Burlington, Massachusetts. The four machines—which are 16 feet long, 6 feet tall and weigh about as much as an SUV—are in various states of production. They’ll be able to 3-D print 100 times faster than existing high-end 3-D printing systems used for aerospace, and at one-twentieth the cost, without the tooling required for traditional manufacturing processes. “It’s the first metal printing press,” says Fulop, an exuberant, heavyset man with a slight accent from his native Venezuela.
HP’s new 3-D printers build items not of plastic but of steel
HP is hoping its new Metal Jet 3-D printers will provide inroads into manufacturing sectors such as automobiles and medical devices.HP
WHEN YOU THINK about 3-D printing, chances are you think of little plastic doodads created by desktop devices like those made by MakerBot. Computing and printer giant HP wants you to think about metal.
Today the company announced the Metal Jet printer, an industrial-scale 3-D printer that builds items not of plastic but of steel.

Five technologies changing construction
Technology is changing every industry, but what are the top technologies accelerating construction?
The construction industry, in general, suffers from a traditional hesitancy to embrace nascent technologies, caused partly because projects take years to plan and complete. Recently, however, progressive construction honchos have begun to harness and realise the potency of tech – whether it’s virtual reality, autonomous drones, artificial intelligence, concrete three-dimensional (3D) printing and much more.
Thanks to incredible tech advancements, great value is generated by optimising efficiency and productivity – at every stage, from planning to construction. Indeed, many within the industry predict that in a decade a building site will look very different. Here follows five of the most game-changing technologies in the construction world.

How to 3D print a bicycle bridge? Study discusses Dutch concrete printing project
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.
Research team develops the world’s first-ever 4-D printing for ceramics
A research team at City University of Hong Kong (CityU) has achieved a groundbreaking advancement in materials research by successfully developing the world’s first 4-D printing for ceramics, which are mechanically robust and can have complex shapes. This could turn a new page in the structural application of ceramics.
Ceramic has a high melting point, so it is difficult to use conventional laser printing to make ceramics. The existing 3-D-printed ceramic precursors, which are usually difficult to deform, also hinder the production of ceramics with complex shapes. To overcome these challenges, the CityU team has developed a novel “ceramic ink,” which is a mixture of polymers and ceramic nanoparticles. The 3-D-printed ceramic precursors printed with this novel ink are soft and can be stretched three times beyond their initial length. These flexible and stretchable ceramic precursors allow complex shapes, such as origami folding. With proper heat treatment, ceramics with complex shapes can be made.

CDC uses HP bioprinters to speed up testing for new antibiotics
The pilot will help test effectiveness against superbugs.
The Center for Disease Control and Prevention is turning to some bleeding edge tech in its bid to stamp out drug-resistant ‘superbug’ bacteria. It’s buying a slew of HP bioprinters (the D300e you see above) as part of a pilot program that could speed up the testing of more effective antibiotics. The machines will give regional labs in New York, Minnesota, Tennessee and Wisconsin their first shot at printing drug samples used for developing and running antimicrobial susceptibility tests. Hospitals won’t have to wait for testing or else risk mistakes like overusing drugs.
The testing will start at CDC’s regional labs in the first quarter of HP’s fiscal 2019 (between November and January). Its initial focus is on widely resistant bacteria. And HP won’t be done once th e bioprinters are in the Center’s hands. HP will help the CDC study the success of the pilot, tweak it if needed, and explore the possibility of wider-scale printer uses if the test proves successful. This may become an instrumental part of fighting superbugs if all goes smoothly.

The Marines 3D printed a concrete barracks
Letting robots do construction jobs on the battlefield frees Marines to fight.
Forging ahead with plans to have robots do “dull, dangerous and dirty” jobs, the U.S. Marine Corps used a 3D printer to create a barracks building out of concrete. The process, which took less than two days, created a hardened living space capable of resisting enemy fire, a real improvement over canvas and nylon tents.
The U.S. Marine Corps moves around a lot, deploying worldwide, often to dusty, remote locations for months at a time. As a consequence, they tend to build a lot of housing for themselves, and it takes a team of ten Marines five days to build a barracks from wood. Not only is construction dangerous, it also prevents those ten Marines from doing other things during those five days.

3D-printed nerve stem cells could help patch up spinal cord injuries
A 3D-printed device, loaded with neuronal stem cells, that can be implanted into an injured spinal cord to help “bridge” the damage,
Spinal injuries can be like downed power lines – even if everything on either side of the injury is perfectly functional, the break can effectively shut down the whole system. Now, researchers at the University of Minnesota have designed a device that could link everything back together again. A silicone guide, covered in 3D-printed neuronal stem cells, can be implanted into the injury site, where it grows new connections between remaining nerves to let patients regain some motor control.

Here’s what NASA thinks Mars houses could look like
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.
