As of 2025, the Factory of the Future 1.0 is the world's largest 3D printer

Housed at the University of Maine, the machine incorporates AI and can utilize bio-based materials to construct homes exceeding 3,000 square feet in size. Homes made from these materials are fully recyclable, as their components can be deconstructed, ground up, and reused as raw materials for printing.

3D printers can create nearly any object that can be digitally designed

Limited only by the size of the printer and the properties of the materials used for printing, fabrications, including household items, toys, props, cases, prototypes, and models, can take anywhere from fractions of an hour to several days to make, depending on design complexity, size, color changes, and printer settings.

Software subscriptions, licenses, and climate control systems add to 3D printing costs

Although the sharing of designs and reduced manual labor suggested the fabrication of prosthetics would be facilitated by 3D printing, particularly in developing regions, software and hardware requirements have posed hurdles to achieving this goal. While some insurance companies have refused to cover 3D-printed limbs, they are covered by Medicare.

Chip-based 3D printers can be pocket-sized and involve no moving parts

View a timeline of 3D printing technology through 2019

The first working 3D printing device was invented in 1983 and utilized stereolithography, a process in which a laser triggers a chemical reaction that hardens liquid resin. Powder-based laser sintering technology was patented in 1987, with metal-based powders first being used for 3D printing in 1997.

The benefits of 3D printing batteries, from safety to sustainability

Rather than using the liquid electrolyte commonly found in lithium-ion batteries, 3D-printed batteries would use a solid layer, which can be custom-built into different shapes, deliver higher energy density by building thinner layers, and be fabricated with fewer raw materials compared to injection molding.

Construction of small, affordable starter homes has decreased 75% since the 1970s

Rising costs aren’t the only thing stopping first-time homebuyers from buying real estate—only 9% of recent new construction is for starter homes. The majority of new housing construction focuses on higher-end buyers due to the increased cost of land, labor, and resources.

US housing costs have risen by roughly 175% between 1991 and 2026—but a growing number of Gen Zers are becoming homeowners anyway. In 2025, 4% of homebuyers were Gen Z, up from 3% the year before.

Data center companies are worsening housing undersupply in some regional markets

With large capital to spend, technology giants have disrupted the real estate market, driving up prices by outbidding commercial and residential developers and intensifying competition for available land. A property purchased over several years for $50M in Prince William County, Virginia, was sold to Amazon for $700M in 2025.

The ancient engineers inspiring modern building practices

Modern concrete structures need replacing every 50 to 100 years, so why are buildings by the Maya, ancient Rome, and ancient China still standing strong? This article details how scientists are looking into humanity's past for clues on how to craft long-lasting structures. Part of the problem is adopting old material recipes to hold up to modern demands.

Why Le Corbusier called a house a 'machine for living'

Modernist architects aimed to boil design down to its essence, stripping ornamentation and frivolity. One of the most famous designers of that movement was Le Corbusier, who famously called a house a "machine for living in." This resource breaks down Le Corbusier's architectural theory and highlights where it can still be found today.

Inhabiting Mars without terraforming might be accomplished with 'worldhouses'

Between 1908 and 1940, "kit homes" that buyers could build themselves were advertised in Sears’ famous catalog—and many of them are still standing today.

The skinniest house in America was built out of spite

John Hollensbury was a brickmaker in the early 1800s, living in Alexandria, Virginia. He also had the misfortune of living next to an alley around 7.5 feet wide where horse-drawn carriages scraped against his wall and rowdy loiterers stood by. To solve his problem, he built what is now known as the Alexandria Spite House. Read more about the home created to end neighborhood riffraff.
