 We’ve followed New Story’s efforts to create affordable 3D-printed homes for a while, including its first prototype model and ambitious plan to build a community in Latin America. That plan has now been put into action and the non-profit has revealed what it calls the world’s first 3D-printed community, which is currently under construction in rural Mexico.

The project, which was created in partnership with Icon and Échale, is located in Tabasco, southeastern Mexico. The team aims to produce 50 homes for families in the area who are living in extreme poverty, often in dangerous and rickety makeshift shelters. So far, two homes have been completed and the families chosen will receive them at a zero interest, zero profit mortgage costing around 400 Mexican Pesos (about US$20 per month), which will run for seven years.

3-D printers are revolutionizing manufacturing by allowing users to create any physical shape they can imagine on-demand. However, most commercial printers are only able to build objects from a single material at a time and inkjet printers that are capable of multimaterial printing are constrained by the physics of droplet formation. Extrusion-based 3-D printing allows a broad palette of materials to be printed, but the process is extremely slow. For example, it would take roughly 10 days to build a 3-D object roughly one liter in volume at the resolution of a human hair and print speed of 10 cm/s using a single-nozzle, single-material printhead. To build the same object in less than 1 day, one would need to implement a printhead with 16 nozzles printing simultaneously!

Watch a massive 3D-printed building take shape

C39FE584-2A75-4AB1-8DDF-3F48BEBDA241

Dubai is now home to the world’s largest 3D-printed two-story building.

On Wednesday, officials in the city’s Warsan neighborhood unveiled the building, which is 9.5 meters (31 feet) tall and has a total area of 640 square meters (6,889 square feet). The structure’s concrete walls were constructed in place using a massive 3D printer — and the entire building serves as a testament to the power of 3D printing in construction.

To make a 3D-printable rocket, Relativity Space simplified the design of many components, including the engine.PHOTOGRAPH: RELATIVITY

Relativity Space may have the biggest metal 3D printers in the world, and they’re cranking out parts to reinvent the rocket industry here—and on Mars.

For a factory where robots toil around the clock to build a rocket with almost no human labor, the sound of grunts echoing across the parking lot make for a jarring contrast.

“That’s Keanu Reeves’ stunt gym,” says Tim Ellis, the chief executive and cofounder of Relativity Space, a startup that wants to combine 3D printing and artificial intelligence to do for the rocket what Henry Ford did for the automobile. As we walk among the robots occupying Relativity’s factory, he points out the just-completed upper stage of the company’s rocket, which will soon be shipped to Mississippi for its first tests. Across the way, he says, gesturing to the outside world, is a recording studio run by Snoop Dogg.

Neither of those A-listers have paid a visit to Relativity’s rocket factory, but the presence of these unlikely neighbors seems to underscore the company’s main talking point: It can make rockets anywhere. In an ideal cosmos, though, its neighbors will be even more alien than Snoop Dogg. Relativity wants to not just build rockets, but to build them on Mars. How exactly? The answer, says Ellis, is robots—lots of them.

…and how this is really about using wood to replace metal

If you’re shopping for a 3D printer, a key consideration is bed size; what’s the largest object you’d realistically need to print?

For the University of Maine’s Advanced Structures and Composites Center, size limitations aren’t so much of an issue. That’s because they’ve got a gantry-style 3D printer that can spit out pieces that are 22×100.

Twenty-two by 100 feet. And ten feet tall.

Icon is an Austin startup that designs 3D-printing technology capable of building tiny homes in about a day for a fraction of the cost of traditional construction methods.

Icon cofounder Evan Loomis told Business Insider that pinpointing an exact cost estimate is tricky, but the company successfully printed a 350-square-foot proof-of-concept home for $10,000 in 24 hours in 2018.

The company isn’t the first to design 3D printing technology for home building, but its unique customization and on-site construction could be revolutionary feats amid a growing demand in the US for affordable housing.

Icon’s latest 3D printer, the Vulcan ll, is available for purchase and is already being put to use.

International Space Station crew 3D-prints meat in space for the first time!

 

F40F71E6-D3FD-4FD7-8A37-DC1E0F7B3D1A

For the first time in the history of space, meat was ‘created’ on the International Space Station (ISS) and no animals were harmed in the making of this 3D bio-printed ‘space beef.’ On October 7, Aleph Farms, an Israeli food company, announced that its experiment aboard the space lab resulted in the first lab-grown meat in space.

Albeit climate change was the main motivation for the company to produce slaughter-free meat, it seems like a breakthrough for space as an entire piece of real, edible meat was grown out of just a couple of cells in a lab- Bovine cell spheroids to be precise.

The experiment was carried out by Russian cosmonaut Oleg Skripochka in the space lab’s Russian segment using a 3D printer developed in Moscow. It involved growing meat by mimicking a cow’s natural muscle-tissue regeneration process. Aleph Farms collaborated with the Russian company 3D Bioprinting Solutions and two U.S.-based food companies to test this method in space.

Meet Olli 2.0, a 3D-printed autonomous shuttle

3791BCCE-CCE9-4790-BA65-9D0C194114CD

From afar, Olli resembles many of the “future is now!” electric autonomous shuttles that have popped up in recent years.

The tall rectangular pod, with its wide-set headlights and expansive windows nestled between a rounded frame, gives the shuttle a friendly countenance that screams, ever so gently, “come along, take a ride.”

But Olli is different in almost every way, from how it’s produced to its origin story. And now, its maker, Local Motors, has given Olli an upgrade in hopes of accelerating the adoption of its autonomous shuttles.

Meet Olli 2.0, a 3D-printed connected electric autonomous shuttle that Rogers says will hasten its ubiquity.

“The future is here; it’s just not evenly distributed,” Local Motors co-founder and CEO John B. Rogers Jr. said in a recent interview. “That’s something I say a lot. Because people often ask me, ‘Hey, when will I see this vehicle? 2023? What do you think?’ My response: It’s here now, it’s just not everywhere.”

While in its early stages, bioprinting of human tissue is an emerging technology that is opening up some exciting possibilities, including the potential to one day 3D print entire human organs. This scientific objective has now grown a little bit closer, with researchers at Carnegie Mellon University reporting a breakthrough that enabled the printing of full-scale heart components that in some cases functioned similarly to the real thing.

The specialized cells that make up the various organs in the human body are glued together by what is known as an extracellular matrix (ECM). This is a web of proteins that not only holds everything together, but also provides the biochemical signaling needed for an organ’s regular, healthy function. Collagen is a protein that plays a key role in this structural integrity, but when it comes to bioprinting, also brings some unique and notable challenges.

Baldness breakthrough uses 3D-printed “hair farms” to grow new hair follicles

520E2D84-D515-4C9F-B665-496448B22190

The 3D-printed structure can for the first time grow human hair follicles entirely in a laboratory dish

An exciting breakthrough from Columbia University researchers demonstrates a new way to grow human hair follicles using 3D printed molds. This is the first time human hair follicle cells have been grown completely in lab conditions, opening up a potentially unlimited source of hair follicles for future hair restoration surgical procedures.

Over the last few decades hair transplantation surgery has rapidly evolved, becoming more sophisticated and successful, however the process has still fundamentally relied on hair follicles being redistributed from one part of the body to another. Growing human hair follicles in laboratory conditions has proved challenging for researchers, ultimately limiting the efficacy of hair restoration surgery, especially in patients without hair already present that can be grafted.

This new breakthrough brings together a couple of recent innovations. First, the researchers created a unique plastic mold using 3D printers. The moulds are designed to resemble a natural micro-environment stimulating hair follicle growth through tiny extensions just half a millimeter wide.
