Texas startup receives $9M to build affordable 3-D printed houses

In the not-too-distant future, a Texas company's 3-D printed homes will be popping up across the world for a fraction of the cost of traditional homes.

"It's our mission at ICON to reimagine the approach to homebuilding and construction and make affordable, dignified housing available to everyone throughout the world," says Jason Ballard, co-founder and CEO of Austin-based ICON LLC. "We're in the middle of a global housing crisis, and making old approaches a little better is not solving the problem."

The 3-D printed homes startup just raked in $9 million in seed funding from a host of investors, including Fort Worth-based homebuilding giant D.R. Horton; Vulcan Capital, a Seattle investment firm launched by Microsoft billionaire Paul Allen, who died October 15; Austin startup accelerator Capital Factory; Austin real estate developer Cielo Property Group; and San Francisco venture capital firm Oakhouse Partners, which is the lead investor.

At this point, ICON executives aren't sure when their homes will be popping up around town. However, Ballard tells CultureMap, "serious conversations" are underway about bringing these homes to Austin and other places around the world.

In March, ICON reaped tons of press when it unveiled a 350-square-foot 3-D home at SXSW — the first home of its kind to receive a construction permit in the U.S. At the time, ICON executives said the home — constructed of concrete and printed in less than 48 hours by 3-D printing robots — cost less than $10,000. By contrast, the median price in September 2018 of a single-family home in the Austin metro area was $302,250.

ICON's first batch of homes is planned for a project in impoverished El Salvador that's being developed in conjunction with New Story, a San Francisco nonprofit that seeks to eradicate homelessness. The first homes there are scheduled to be printed next year.

ICON is targeting a per-home cost of $4,000 in El Salvador. Relying on technology upgrades, ICON hopes to create each 3-D home in less than 24 hours.

"While prices to print homes will vary from country to country and state to state," Ballard says, "the big takeaway is that downloading and printing a home has the potential to cost half of standard construction costs."

Homes at the development in El Salvador will measure 600 to 800 square feet — around the size of a typical one-bedroom apartment. Eventually, ICON aims to print homes in the 1,500- to 2,000-square-foot range.

Among the advantages of 3-D printed homes cited by ICON are:

Speedy construction
No manual labor
Little generation of leftover construction materials
"Tremendous" design freedom

There's a positive environmental impact with this construction process as well.

"Conventional construction is slow, fragmented, wasteful, and has poor thermal properties that increase energy use, increase operating costs, and decrease comfort," Ballard says. "Also, conventional materials like drywall and particleboard are some of the least resilient materials ever invented."

Astros and Rockets launch new streaming service for Houston sports fans

Sports Talk

Houston sports fans now have a way to watch their favorite teams without a cable or satellite subscription. Launched December 3, the Space City Home Network’s SCHN+ service allows consumers to watch the Houston Astros and Houston Rockets via iOS, Apple TV, Android, Amazon Fire TV, or web browser.

A subscription to SCHN+ allows sports fans to watch all Astros and Rockets games, as well as behind-the-scenes features and other on-demand content. It’s priced at $19.99 per month or $199.99 annually (plus tax). People who watch Space City Network Network via their existing cable or satellite service will be able to access SCHN+ at no additional charge.

As the Houston Chronicle notes, the Astros and Rockets were the only MLB and NBA teams not to offer a direct-to-consumer streaming option.

“We’re thrilled to offer another great option to ensure fans have access to watch games, and the SCHN+ streaming app makes it easier than ever to cheer on the Rockets,” Rockets alternate governor Patrick Fertitta said in a statement.

“Providing fans with a convenient way to watch their favorite teams, along with our network’s award-winning programming, was an essential addition. This season feels special, and we’re committed to exploring new ways to elevate our broadcasts for Rockets fans to enjoy.”

Astros owner Jim Crane echoed Feritta’s comments, adding, “Providing fans options on how they view our games is important as we continue to grow the game – we want to make it accessible to as large an audience as possible. We are looking forward to the 2026 season and more Astros fans watching our players compete for another championship.”

SCHN+ is available to customers in Texas; Louisiana; Arkansas; Oklahoma; and the following counties in New Mexico: Dona Ana, Eddy, Lea, Chaves, Roosevelt, Curry, Quay, Union, and Debaca. Fans outside these areas will need to subscribe to the NBA and MLB out-of-market services.

Rice University researchers unveil new model that could sharpen MRI scans

MRI innovation

Researchers at Rice University, in collaboration with Oak Ridge National Laboratory, have developed a new model that could lead to sharper imaging and safer diagnostics using magnetic resonance imaging, or MRI.

In a study recently published in The Journal of Chemical Physics, the team of researchers showed how they used the Fokker-Planck equation to better understand how water molecules respond to contrast agents in a process known as “relaxation.” Previous models only approximated how water molecules relaxed around contrasting agents. However, through this new model, known as the NMR eigenmodes framework, the research team has uncovered the “full physical equations” to explain the process.

“The concept is similar to how a musical chord consists of many notes,” Thiago Pinheiro, the study’s first author, a Rice doctoral graduate in chemical and biomolecular engineering and postdoctoral researcher in the chemical sciences division at Oak Ridge National Laboratory, said in a news release. “Previous models only captured one or two notes, while ours picks up the full harmony.”

According to Rice, the findings could lead to the development and application of new contrast agents for clearer MRIs in medicine and materials science. Beyond MRIs, the NMR relaxation method could also be applied to other areas like battery design and subsurface fluid flow.

“In the present paper, we developed a comprehensive theory to interpret those previous molecular dynamics simulations and experimental findings,” Dilipkumar Asthagiri, a senior computational biomedical scientist in the National Center for Computational Sciences at Oak Ridge National Laboratory, said in the release. ”The theory, however, is general and can be used to understand NMR relaxation in liquids broadly.”

The team has also made its code available as open source to encourage its adoption and further development by the broader scientific community.

“By better modeling the physics of nuclear magnetic resonance relaxation in liquids, we gain a tool that doesn’t just predict but also explains the phenomenon,” Walter Chapman, a professor of chemical and biomolecular engineering at Rice, added in the release. “That is crucial when lives and technologies depend on accurate scientific understanding.”

The study was backed by The Ken Kennedy Institute, Rice Creative Ventures Fund, Robert A. Welch Foundation and Oak Ridge Leadership Computing Facility at Oak Ridge National Laboratory.
