Fast Forward: 3D Building Blocks Are the Secret Of This Old (Digital) House | Innovation

Made of sustainable, raw materials, the houses can be customized to fit individual design tastes and aim to eliminate waste.

Four hundred years ago, when architects began to build tall, narrow houses along Amsterdam’s winding canals, they invented a style that would become popular around the world.

Now, designers from the Dutch firm DUS Architects are re-imagining the structures in a very modern way, breaking ground on what could become the world’s largest 3D-printed structure.

Dozens of industries, from athletic wear to health care, have chased after 3D printing in the past few years. Construction isn’t new to the game, but most efforts have focused around individual building parts—steel rods or concrete beams, for instance. Much of the race in housing has focused on speed: In China, one company recently built 10 houses measuring 2,100 square feet each in a day, and a professor from University of Southern California says he can build a 2,500 square foot house—including the plumbing and wiring—in about 20 hours.

DUS’ venture, though, has loftier aims—for large houses but also structures that could conceivably be used for shops or restaurants. It also relies mostly on recycled materials and claims to better handle more complicated design elements (which means, beyond disaster and poverty relief, 3D printed houses could also help repair or add to the veneer of historic neighborhoods without as much aesthetic disruption).

It also, unlike the other projects, is inviting the public into the process.

As in traditional construction, the process begins with blueprints. Digital design files are fed into a device called the KamerMaker (“room builder”), a 20-foot-tall printer that converts a digital design into code. The machine prints the interior and exterior of a room in a single round, squeezing recycled bioplastic layer by layer from floor to ceiling, leaving space for pipes and wiring.

Once completed, the individual rooms become three-dimensional building blocks. For the pilot project, blocks will be stacked to form a 13-room house overlooking one of the city’s central canals.

Though the first room in that project won’t be done until this summer, the venture—open to the public as an expo—could revolutionize modern architecture, designers say. The blocks can be rearranged to create different layouts depending on occupants’ needs. Since the house is printed and assembled on-site, says expo manager Tosja Backer, there is little waste and minimal transportation costs. And digital design files can be sent to sites around the world and then produced locally, says expo manager Tosja Backer, “to suit the location and context.” In areas struck by disaster, for instance, the KamerMaker could print with local waste materials.

Granted, it will be some time before we reach the age of print-it-yourself houses. It will take three years to complete the house, DUS says; along the way, designers are bound to hit roadblocks and challenges, some of which they may not be able to solve on their own. But in some ways, Backer says, that’s the point: Because the site is both an open workplace and exhibition, anyone, from engineers to visitors who pay the $3 entry fee, can help improve the technology.

“Sharing knowledge helps a project grow,” he says. “A building project is not just about the building: it’s about the context, the users, and the community. They are all part of the process.”

Fake: “Houses were already being printed on 3D printers in the 1930s”

Fake News

A message appeared on social networks that already in the 1930s people were able to print residential buildings on a 3D printer. According to the author of the idea, now this technology is being hidden, since such houses would be very cheap, which would allegedly harm the market economy. The mailing is accompanied by a video in which concrete walls are erected using an unusual device. We tell you what is actually shown in the video and why this is not a 3D printer.

The video being distributed was actually filmed in the late 1930s in the USA. The footage shows the construction of the building according to the method, which was patented in 1941 by William E. Earschel.

The method itself was to use a special device that was able to erect and immediately smooth concrete walls. However, it is difficult to call it a 3D printer, since the construction process is still not fully automated. On the videos that can be found on the Web, it can be seen that workers manually load concrete already mixed in advance into the machine, and the device itself lays it out only in a circle and nothing else.

The patent filed by the inventor states that the machine can be set up to place concrete in conical or hyperbolic shapes, but this setting must be done by hand. The patent itself was valid for 20 years. It expired in January 1961. Nevertheless, the description and drawings are still kept in the public domain. Therefore, this technology is not secret and anyone can access it.

William E. Ershel's technology differs from today's 3D printers in many ways. 3D printers are programmed in such a way as to lay out the material in certain forms in advance, while the forms can be of absolutely any complexity. The printing process is almost completely automated and does not require heavy physical labor of people.

The theory that 3D printing at home is currently unprofitable is a lie. In fact, such projects are being developed and are considered very promising. The problem today lies only in the fact that not all buildings constructed in this way meet the safety and quality requirements put forward by the authorities of the states. However, in some countries this issue is already being addressed. For example, 3D-printed houses already exist in Denmark, India and Germany. According to the World Economic Forum, it is this technology that in the future may be the key to solving the problem of providing people with affordable and high-quality housing.

So, the distributed video is not a 3D printer at all, but a technology for building concrete walls, patented in 1941 in the USA. No one hides it from people - drawings and a description of the technology are available in the public domain. Modern 3D printers are significantly different from what was patented in 1941. To date, there are already residential buildings printed using a 3D printer, and they plan to develop these technologies further.

Thus, the mailing that at 19In the 30s, people were able to print houses on a 3D printer - not true.

The world's first 3D printed house

June 21, 2016

The world's first 3D printed building has appeared in the capital of the United Arab Emirates. It was erected in the city center near the Dubai International Financial Center.

A 250,000 square meter one-story office building was erected in the city center near the Dubai International Financial Centre. It has electricity, telecommunications, water supply and an air conditioning system.

Construction using new technology cost $140,000. This is about 50% cheaper than the same building erected in the traditional way.

Construction team consisted of 19 people. One monitored the work of a 3D printer, eight assembled a house from printed elements, the rest carried out engineering communications. The creation of the office building took 17 days, another two days were spent on decorating the premises inside.

For construction, a 3D printer 6 m high, 37 m long and 12 m wide is used. Workers only need to install the rails along the contour of the future house and the 3D printer structure, the computer will do the rest.

The robot moves along the rails, spreading concrete until the house is completed. It remains for builders to install windows and doors in prepared openings.
