Request a free trialRead an article about the first 3D printed houses?
3D printing has been used in construction for several years now. In this article, you will learn about the first real houses printed on 3D printers.
3D printing of houses is still quite new to the layman. While construction 3D printing technologies have been developed for many years, only a few "real" projects have already seen the light of day. We are still far from technology taking over conventional construction methods. But with each new project, she is getting closer to becoming mainstream. nine0005
There are many benefits to 3D printing. For example, the cost of a 3D printed house can be much lower. And it will take much less time to build.
In order to draw a line under what has already been achieved in this area and show some interesting projects, we have devoted an article to the "first" and the best. These projects will always remain milestones in the construction 3D printing industry as they set the stage for future advances in the field.
First 3D printed house in Germany
Germany is a country often associated with cutting edge engineering, so let's start our list with Germany's first ever 3D printed house.
The house itself is located in Beckum, a city that is partly located in North Rhine-Westphalia, next to Holland and Belgium. This is the first 3D printed house to be fully certified to official building codes. This project will give way to many other 3D printed construction projects in Germany as well as the rest of Europe. nine0005
The project is the result of a collaboration between German construction company Peri and Danish construction 3D printing firm COBOD. Peri is a large corporation that operates not only in Germany, but throughout the EU. Its portfolio includes many products, including scaffolding and formwork solutions that every construction site needs.
Peri followed the construction 3D printing segment for years before acquiring a stake in COBOD in 2018. Now they are pushing the technology together and further. The construction of the house in Beckum began two years after the acquisition of the share. nine0005
For 3D printing at home, a BOD2 modular 3D printer from COBOD was used. The printing itself took just over 100 hours.
• Built: (started) September 17, 2020
• Commissioned: summer 2021
• Where: Beckum, North Rhine-Westphalia, Germany
• By: Peri, COBOD
First occupied 3D printed home in the US
Several homes have been printed in the US, but this home is the first officially occupied home, according to CNN. Its creators: the construction company Alquist and the humanitarian organization Habitat for Humanity Peninsula. nine0005
From a distance, you might think that this is an ordinary house. However, when approaching it, the layered structure of the concrete walls becomes noticeable. After all, 3D printing creates an object in layers.
Surprisingly, the 111.5 square meter concrete structure of the house (was printed in about 12 hours, significantly faster than traditional construction methods would allow.
The house was reportedly purchased by April Springfield, who lives there with her son and dog She bought the house through Habitat for Humanity's housing program, and given that the nonprofit's goal is to help solve the global housing crisis, it makes sense to use 3D printing to create affordable homes that will make many people's dreams of home ownership come true.0005
• Built: 2021
• Commissioned: December 22, 2021
• Where: Williamsburg, Virginia, USA
• By: Alquist 3D, Habitat for Humanity Peninsula, Greater Williamsburg
The first five-story 3D printed house
This project, made by the Chinese company WinSun, is a real record holder. It is a 3D printed five-story residential building with a height of 10 meters - the tallest 3D printed building so far.
The house is located in Suzhou Industrial Park in Jiangsu province in eastern China. It stands next to a mansion that was also built by WinSun using a concrete 3D printer.
Looking at the WinSun designs, you can't help but notice that they don't look like they've been 3D printed. Usually 3D printed structures are gray in color, the layer lines are clearly visible. But WinSun adds color and makes walls smoother. Nowhere is it stated how the company achieves the smoothness of the walls, but we assume that the workers smooth them by hand. WinSun projects are not like the ones we're used to. nine0005
• Built: Winter 2014
• Commissioned: Not specified
• Where: Suzhou, Jiangsu, China
• By: WinSun
First 3D printed biodegradable house
Can you guess that there is rice in the walls of this house?
Most 3D printed buildings are made from concrete mix. But this project is different from the rest. With the aim of creating housing solutions with little to no environmental impact, Italian company WASP 3D printed Gay's house using soil and agricultural waste. nine0011 WASP developed the sustainable blend in collaboration with Ricehouse, a company that specializes in using natural and agricultural materials such as clay and rice in construction.
The house is named Gaia in honor of the ancient Greek goddess of the earth. In fact, 25% of the mixture contains local soil, 10% hydraulic lime, 25% rice husks and 40% crushed rice straw (a by-product of rice production at harvest).
An innovative solution not only in terms of material, but also in the design of the walls themselves. The specific corrugated structure was used to provide ventilation on warm days as well as insulation on cold periods, virtually eliminating the need for air conditioning. nine0005
Gay's house is small - about 20 square meters. The wall printing took only 10 days, while the estimated materials cost is just under $1,000.
• Built: not specified
• Commissioned: October 7, 2018
• Where: Massa Lombarda, Ravenna, Italy
• By: WASP, Ricehouse
AirBnB's first 3D printed house
The perfect weekend getaway.
You can find many different types of accommodation on AirBnB, but what about a 3D printed home? nine0005
The so-called Fibonacci house is the first 3D printed house to be offered for booking through AirBnB. Considering that it is located in rural British Columbia, it will be a wonderful place to stay.
Although the Fibonacci house looks small, it has a lot to offer vacationers. About 35 square meters is enough to accommodate up to four people.
The concrete walls of the house were designed and printed by Dutch 3D printing firm Twente. 20 concrete parts were produced offsite in just 11 days. The material was produced by Laticrete. The parts were later transported and assembled at their current location. nine0005
• Built: 2020
• Commissioned: Not specified
• Where: Kootenays, British Columbia, Canada
• By: Twente Additive Manufacturing
First 3D printed houseboat
Prvok is not only the first 3D printed house in the Czech Republic, but the world's first floating 3D printed house on a pontoon.
The project was implemented by the start-up company Scoolpt. The concrete structure of the houseboat took only 22 hours to print. nine0005
Approximately 43 square meters of living space divided into bathroom, bedroom and living room with kitchen. Weight isn't usually discussed in the context of houses, but given that this one is on water, it's interesting to note that Prvok weighs 43 tons.
The house is equipped with a built-in recirculating shower and tanks for drinking and municipal water and has a service life of at least 100 years.
• Built: June 2020
• Commissioned: August 18, 2020
• Where: Prague, Czech Republic
• By: Scoolpt
Europe's first 3D printed residential house
Not every 3D printed house has visible line layers.
More often than not, 3D printed houses are demos made to show what the technology can do. For most of them there is no information about the actual residents. But in 2017, the couple did move to live in a 3D printed house located in Nantes, France. Thus, the house of "Yanov" became the first of its kind, which was inhabited in Europe. nine0005
The house is a project of the University and the Laboratory of Digital Sciences of Nantes. An interesting aspect of the project is the special technique used in its construction by BatiPrint3D. Instead of 3D printing a concrete structure, the robotic arm created wall shells using polyurethane, a material used for insulation. Later, these membranes were filled with concrete.
It took a total of 54 hours to print. It took a little over 4 months to complete the construction. Mainly due to the fact that the rest of the components were created using conventional means. House area - 95 square meters.
• Built: 2017
• Commissioned: March 2018
• Where: Nantes, France
• By: University of Nantes, Nantes Digital Science Lab
India's first 3D printed house
This building was built in a couple of days.
India's first ever 3D printed house was completed back in 2020. The project was carried out by construction startup Tvasta, founded by graduates from the Indian Institute of Technology Madras. In fact, the institute's Chennai campus was chosen as the location of the building. nine0005
The significance of this project lies in its possible impact on the solution of the housing crisis worldwide and in India in particular. The ability to build such a house within a few days and at a low cost cannot be underestimated.
House 55.7 sq.m. with a spacious layout, one bedroom, combined kitchen and living room.
The concrete structure of the house was 3D printed off site and the parts were later transported and assembled on campus. The foundation, meanwhile, was built using the conventional method of pouring concrete into the ground. nine0005
• Built: 2020
• Commissioned: Not specified
• Where: Chennai, India
• By: Tvasta Construction
Africa's first 3D printed house
Back in 2019, in the Moroccan city of Ben Guerir, Spanish firm Be More 3D created Africa's first 3D printed house. The project originated during the team's participation in the Solar Decathlon in Africa. This is an international competition during which teams design and build solar-powered houses. nine0005
Be More 3D printed house 32 sq.m. in about 12 hours, took first place and received the title of the most innovative startup.
Be More 3D didn't stop building in Africa and later created the first 3D printed house in Spain and developed its own concrete 3D printer in partnership with several corporations from the automation and materials industries.
• Built: 2019
• Commissioned: Not specified

First 3D printed home for sale in the US
Last on our list is the first 3D printed home for sale in the US.
This house was printed in the same place by SQ4D, a company specializing in the development of robotic building systems. The building was printed with SQ4D's Arcs concrete extrusion system and has a 50-year warranty on the printed structure.
Living area of 130.7 sq.m. with three bedrooms and two bathrooms. There is also a garage for 2 cars. nine0005
The house was listed for sale in January 2021 for $299,999. Considering the size of the house and the fact that it is priced 50% below the cost of comparable newly built houses in the same area, the deal is pretty good.
• Built: 2020
• Commissioned: 2021
• Where: Riverhead, New York, USA

Basically, this site acts as an online store where you can buy 3D printed parts, or order your own 3D model to be printed. But if you look closely enough, you can find people who sell their products and also offer the files you need so you can print them yourself. nine0005
