An accessory dwelling unit (ADU) is a secondary living space that is attached to a primary residence. This can be anything from a garage, a new basement, an attic, or even a Zumba studio. These homes are not only cost-effective—they also can last for years with regular maintenance. 

Here are the top 3D printed ADU builders you should check out if you wish to remodel or expand your home and increase its value:

Mighty Buildings

Mighty Buildings is based in Oakland, CA, and is known for building technologically advanced and sustainable ADU homes using patented 3D printing technology as well as robotics automation.

The company’s high-tech resources allow it to build modular homes much faster than its traditional counterparts. Its 3D printers use special thermoset composite material that is resistant to UV light.

What We Like About It

Besides being certified under California’s Factory Built Housing program, Mighty Builders is also the first organization to meet UK 3401 standards for examining structures and assemblies.

The company is also backed by notable organizations and investors from Silicon Valley, including Zeno Ventures. 

Boxabl

Boxabl is revolutionizing affordable housing due to its foldable 3D ADU structures and other sustainable housing options. Its original product, Casita, comes with a full-sized bathroom, tall ceilings, big windows, and even kitchen appliances

The company’s main aim is to drastically reduce housing costs by using assembly-line mass production techniques so their customers can get fully-constructed and sustainable homes sooner rather than later.

What We Like About It

The company re-engineers buildings by choosing different materials and manufacturing methods that make its structures outperform fire resistance, wind resistance, and energy rating standards.

Its original plant fabricated one house every 90 minutes. One of the first products was a 20 x 20 prefab studio apartment that could be installed in a backyard in under an hour. 

ICON

ICON is a 3D ADU builder that is passionate about advancing the state of home construction and making it as affordable as possible without sacrificing efficiency.

In 2008 it became the first company to secure a building permit to create a 3D printed home, and it has attracted hordes of investors ever since. ICON leveraged that support to develop software and robotics technology that has driven a number of their projects.

What We Like About It

ICON uses a special Vulcan construction system that can produce homes and structures that are up to 3,000 square feet, and each one is built to International Building Code (IBC). These last longer than concrete masonry unit (CMU) structures. 

PERI 3D

PERI was founded back in 1969 by Artur Schwörer and his wife, Christi. Over the years, the company expanded into 3D ADU homes to make the construction process easier, more reliable, and safer. The company has headquarters in Weißenhorn, Germany, where it produces new system devices. 

What We Like About It

The main aim of all PERI developments is the complete integration of formwork and scaffolding solutions in BIM simulations to ensure optimized solutions for each project.

Plus, the company provides accurate technical documentation such as implementation drawings as well as verifiable statistical calculations. 

Apis Cor

Apis Cor is one of the first ADU builders to develop special 3D equipment that can print whole buildings onsite. Its aim is to upgrade that technology so it can create buildings on Earth and beyond. The company is known for its 3D printer, which can be transported to different sites due to its compact design.

What We Like About It

The Apis Cor 3D printer is almost completely automated and requires just two people to run, which cuts down on the manpower you need to pay for.

Plus, it can be installed in just half an hour, after which it gets to work. The technology cuts down costs by about 40% compared to traditional building techniques. 

Winsun

Winsun is one of the ADU builders focused on constructing and decorating large-scale public buildings such as stadiums, theatres, conference halls, industrial parks, and even clubs.

Winsun uses special reinforced concrete (SRC) developed on its own for the structures it creates. The concrete not only makes buildings resilient against harsh weather conditions but also provides insulation. 

CyBe Construction

The company also boasts a range of 3D Delta WASP printers that meet small and large printing needs. The aim of Wasp is to build ‘zero-mill’ homes using materials that can be found in nature. 

What We Like About It

WASP owns the first service in Italy for 3D printing of large materials via an industrial warehouse that is thousands of square meters in size. Its main aim is always to tackle large prints using its technology.

The company built and uses a gantry-style 3D printer that can be used to build complete commercial and residential buildings. Its special ARCS system was designed to be sustainable on and off job sites, and it can be used to create more than buildings.

What We Like About It

The ARCS 3D printer used by the company employs about the same amount of electricity as a standard hairdryer, and its carbon-neutral building process also ensures eco-friendly construction. The entire process used to print structures is highly automated, meaning it doesn’t waste materials. 

SLIK Build

SLIK offers a range of concrete products at a square meter rate which allows customers to save money. This includes reduced overheads since they don’t have to use any heavy machinery, molds, or additional labor, making it ideal for small, custom, and complex projects.

Conclusion 

3D buildings are here to stay. As the climate crisis becomes a very real threat and we look towards Mars as an alternative home planet, looking into 3D AUD builders should be a priority. So if you wish to save time, money, and resources for a construction project, refer to the aforementioned companies.
