Is 3D printing the future of affordable housing? It certainly seems possible. The burgeoning technology has the potential to construct houses faster and cheaper than with traditional building techniques, and has already resulted in a low-cost housing project in Mexico. Now global housing nonprofit Habitat for Humanity is creating a 3D-printed home that it hopes will become a blueprint for affordable housing.

The prototype house is currently under construction in Tempe, Arizona, and is expected to be completed by September and serve as home to a low-income family. It will have a usable floorspace of 1,738 sq ft (161 sq m) and will contain three bedrooms and two bathrooms, as well as a living room and kitchen, plus a garage.

More ambitiously though, Habitat for Humanity aims to build on its experience making the home to produce a series of affordable 3D-printed houses. How affordable? We reached out to the nonprofit and received the following statement.

3D-printable phase-change materials insulate buildings better at scale
By Michael Irving
July 12, 2021
Heating and cooling systems are some of the biggest energy guzzlers in use, so passive temperature control could be a good way to reduce emissions. Phase-change materials (PCMs) show promise for this, and now engineers at Texas A&M have developed a new PCM composite that can be 3D printed.

The name “phase-change materials” is pretty self-explanatory – these materials will switch between phases of matter as the temperature changes. One of the most promising applications for this technology is insulation: the PCM melts into a liquid as it absorbs heat, cooling its surroundings. As the ambient temperature cools, the material will solidify again, releasing its stored heat.

In the past, PCMs have been used in coffee cups to keep hot drinks hot, fabrics that keep wearers warm or cool as needed, liquid coatings that prevent frost build-up, and in building materials that better regulate indoor temperature. It’s that last one that the researchers on the new study wanted to improve.

Habitat for Humanity Deploys First 3D Printed Home
https://www.extremetech.com/extreme/330 ... inted-home
By Adrianna Nine on December 28, 2021 at 1:43 pm

Habitat for Humanity, a non-profit that builds and repairs homes in partnership with lower-income families and individuals, has officially signed over its first 3D printed home.

Habitat for Humanity partnered with Alquist to build the 1200-square-foot house in Williamsburg, VA. Alquist, a large-scale 3D printing company, aims to make home ownership more accessible across demographics using advanced, environmentally-friendly building techniques. Not only does the company’s strategy reduce build time, but its 3D printed concrete homes are said to boast longer life expectancies than traditional wood-framed structures. Concrete walls also stand up well against tornadoes and hurricanes and help to reduce homeowners’ energy bills, as they offer better insulation than wood and drywall.

The US will soon be home to the world’s first 3D-printed hotel
It will be a sprawling 62-acre desert oasis located in Marfa, Texas.
https://interestingengineering.com/inno ... nted-hotel

Hospitality world genius Liz Lambert, 3D construction start-up Icon, and Danish design firm BIG, have joined forces to bring to Texas the world’s first 3D-printed hotel in 2023. More specifically it will be in Marfa, according to a blog on BIG’s website.

The Danish architect might seem familiar as he is already the brain behind renowned architectural wonders in the VM Houses and Mountain Dwellings, a couple of housing complexes based in Copenhagen.

Meanwhile, Lambert is the founder of El Cosmico, a camping site located in Marfa that has become a must-visit for travelers worldwide. The new venture will see the 3D-printed hotel built on the same ground using innovative technology.

For the time being, El Cosmico is only 21 acres. But very soon the 3D-printed expansion will nearly triple that area, transforming it into a sprawling 62-acre desert oasis with all the necessary elements that truly make a summer vacation enjoyable and restful.

There will be a massive infinity pool kitted with cabanas and captivating guest dwellings. It will be Icon’s extremely efficient home-sized 3D printer that will be in charge of churning out these mesmerizing locations.

Curving data center to be Europe's largest 3D-printed building
By Adam Williams

https://newatlas.com/architecture/europ ... ing-cobod/

3D-printed architeture has gone from strength to strength over the past few years, with the cutting-edge tech used to build everything from an experimental Mars habitat to a string of major residential works in the United States. The latest notable advance comes from Germany, where an ambitious new data center is under construction that's hailed as Europe's largest 3D-printed building.

The project, which doesn't have an official name yet, is located in Heidelberg. Its design leans into the aesthetics of 3D-printed architecture and will feature an eye-catching wavy exterior that will also incorporate some greenery. Its interior will be used to host cloud-computing infrastructure.

It will have a length of 54 m (177 ft), a width of 11 m (36 ft) and a height of 9 m (29.5 ft), which as far as we can tell will indeed make it Europe's current largest 3D-printed structure, though in this fast-moving area it's hard to say how long that will last. It's being built using the same COBOD BOD 2 printer used on 2020's 3D-printed two-story house in Antwerp.

"World's largest" 3D-printed building nears completion in Florida

With projects like the 100-house development in Austin, Texas, and NASA's Mars habitat, 3D-printed architecture is really taking off in the United States. Another major milestone comes from Printed Farms, which is nearing completion on what it calls the world's largest 3D-printed building, a "luxury horse barn" in Florida measuring roughly 10,100 sq ft (almost 940 sq m).

To get the firm's bold claim out of the way first, as far as we can tell, the project is indeed the world's largest 3D-printed building, though it's such a fast-moving area of technology that there may well be a company out there about to take the wraps off something even larger.

The total length of the single-story structure is 155 ft (47 m), and its width is 83 ft (25 m) while its height comes in at 13 ft (4 m). To help build it, Printed Farms made use of a single COBOD BOD2 3D printer, which was the same model used to create Europe's first two-story 3D-printed home.

3D-printed apartment building provides affordable housing in Germany
By Adam Williams
November 06, 2023
3D-printed construction continues to grow in popularity worldwide, and the latest example is an ambitious new low-rise apartment building in Germany. The project will incorporate cutting-edge 3D printing technology – as well as timber – and will be used to provide affordable social housing.

The unnamed development is described by 3D printer manufacturer COBOD as Germany's first 3D-printed social housing apartment building. It's being built in the town of Lünen by Peri 3D Construction, and follows the firm's curvy data center revealed elsewhere in Germany earlier this year. It will consist of three floors, each of which will host two rental apartments subsidized by the local government. The six apartments will range from 61 sq m (670 sq ft) to 81 sq m (890 sq ft), and the building's total footprint will be 651 sq m (7,150 sq ft).

Structurally, it will be a little more complex than most 3D-printed buildings we've covered. The first two floors will be built using a COBOD BOD 2 printer, which is the same model used on the recent Indian post office and earthquake-resistant house. The machine will carry out its construction work on-site by extruding a cement-like mixture out of a robot-operated nozzle in layers, building up the structural shell of the first two floors while following a blueprint. The entire printing process is expected to take 100 hours.

As 3D-printed architecture continues to grow in popularity, architects and designers are finding more and more creative uses for the cutting-edge tech. A new project by Studio RAP is the latest example of this and uses a 3D printing system to transform a retail store with a decorative knitted fabric-like ceramic facade.

The project, named Ceramic House, is located in a busy area of Amsterdam, the Netherlands, and involved giving a luxury boutique store a facelift, helping it stand out among the surrounding buildings.

Influenced by textiles, the facade is made up of 3D-printed ceramic tiles, which were produced in a similar fashion to Studio RAP's previous project, New Delft Blue. The firm used an industrial robotic arm fitted with a custom extruder, which pushed a clay based mixture out of a nozzle in layers, according to a predetermined pattern, to build up each clay tile. The tiles measure roughly 40 x 20 cm (15.5 x 7.5 in) each and were glazed and fired to create a ceramic finish before being attached to the facade. On the lower floors, the tiles are finished in white, while the higher floors are made up of three shades of red.
