While it may be true that the mother of invention is necessity, in today’s startup market, a more important factor is disruption. That’s where HIVE 3D, a Texas-based leader in constructing eco-friendly 3D printed homes, flourishes.

HIVE 3D was already revolutionizing the home-builder industry with its lightweight gantry system and mobile robotic arm system to 3D print its homes, but it took a giant leap further with its partnership with Utah-based Eco Material Technologies, North America’s leading producer of sustainable cement alternatives.

Together, they are building the world’s first near-zero-carbon, 3D-printed homes. Using Eco Material’s cement mixture called PozzoCEM Vite, which has 92 percent lower emissions than traditional concrete that can set in just a few minutes, they are focusing on providing a sustainable, cost-efficient and affordable housing solution.

“We want our homes to last 1,000 years,” Timothy Lankau, CEO, Hive 3D CEO, tells InnovationMap. “We want archaeologists to dig them up and wonder what they were. I mean, you go to the Parthenon in Rome, and it looks similar today to how it did 2,000 years ago because the materials are so stable.

“Concrete's just a very stable material. It doesn't change over time, and that's also why building with stone and masonry is important for the future. We think it's more sustainable because it's ultimately going to be better in terms of longevity.”

Key collaboration

Eco Material Technologies and HIVE 3D’s collaborative mission began through a mutual desire to develop sustainable and eco-friendly solutions for the construction industry.

“Both companies recognized the pressing need to reduce the environmental impact of traditional construction materials and processes and the need for affordable, high-quality housing,” says Grant Quasha, CEO of Eco Material Technologies. “The partnership between the two companies began when Eco Material Technologies reached out to HIVE 3D to explore the potential of incorporating their eco-friendly materials into 3D printed construction.

“HIVE 3D recognized the opportunity to combine their expertise with sustainable material solutions. The finished product of this collaboration is an eco-friendly construction material that can be 3D printed into various structural elements like walls, floors and columns.”

HIVE 3D’s first full project, a 3,150-square-foot home located in Burton, Texas, was printed with a rotating team of just four people using PozzoSlag, which replaces 50 percent of the portland cement in concrete and has been used in roads and bridges in Texas for over a decade.

The home used several innovations that hadn’t been used in a 3D printed house before, including parametric wall designs, foamcrete wall insulation, and pigmented concrete layers.

“Our product is more sustainable because it utilizes proprietary technology that allows for the use of alternative materials to replace the clinker and processes from traditional cement that contribute to its high emissions,” says Quasha. “It is estimated that the portland cement industry contributes to 8 percent of global emissions annually, but by utilizing Eco Material Technologies' cement replacement solutions ... builders can significantly decrease their carbon emissions without compromising on the product's setting time or long-term strength."

Each ton of portland cement replaced by a ton of Eco Material's products, PozzoSlag or Pozzocem, reduces emissions by close to one ton, Quasha explains.

The Calais project, located in Round Top, Texas, behind the Halles, an antique shopping and design destination, broke ground in March 2023 and will feature a collection of tiny homes known as casitas, including studio, single-bedroom and two-bedroom models, ranging from 400 to 900 square feet.

“These small homes will serve as a model for affordable and eco-friendly housing throughout the country,” says Lankau. “We plan to build them at a speed and cost point that is unprecedented in the affordable housing space.

“Ultimately, we want to build houses at a disruptive price point. We want to be vertically integrated and put our homes on the market at a significant discount to market wherever they are. And by significant, we're talking 20 or 30 percent. That's our goal.”

The right resources

HIVE 3D worked with CyBe Construction to create a mobile construction 3D printer and mixing system that allows the printing mortar to be mixed onsite, which eliminates a significant amount of labor and time, which means those savings can be passed on to the consumer.

“We worked with a company called CyBe in the Netherlands to build a robotic arm, and that arm has about an 11-foot reach, and it can go all the way in a circle around itself,” says Lankau. “So, it drives around the foundation of the house, printing sections of the house at a time. So, it'll print a section, drive to the next section, and print the next section.

“So instead of having this many different materials and these many different traits, people that do all these different things, we have a machine that just uses one material and prints the wall.”

HIVE 3D has an internal engineer that works through all of the structural issues that may come up on projects and helps them build homes with monolithic, foot-thick concrete walls with rebar and steel supported in them.

According to Lankau, their 3D printed homes are tornado-proof, hurricane-proof, pest-proof, bullet-proof and can virtually withstand anything because of the sustainable materials used to build them.

“They're everything-proof,” says Lankau. “Just because of the natural strength of the concrete and the steel we use to create them, they can support millions of pounds. So, it's actually a stronger material than a typical house. By a factor of 100. Like I said, it's bulletproof and tornado-proof. You could drive a car into it, and it would total the car. I mean, it's a very, very sturdy structure.”

A bright future

Moving forward, HIVE 3D would like to continue to innovate and advance its 3D printing technology by leaps and bounds.

“The science fiction goal here, which is maybe a five-year goal, is to be able to drive onto a site, press a button, and watch the robots work,” says Lankau. “We want to be a significant home builder. So, in five years, we want to be building a lot of houses quickly and affordably and we want to continue to automate more and more of the process.”

Right now, there is no formal process for commissioning a HIVE 3D printed home. Perspective customers are directed to the website, then put in a request to build a home, go through a screening process and if the project is a good fit, they'll put that project into their pipeline.

“We can build them quickly. It's just a matter of getting to them,” says Lankau. “We're also going to be doing some developments in Texas probably to start. We also have some international things that we'll be looking into next year. But right now, it's mostly in Texas. We'll be building some developments and putting those homes on the market. We hope to have some out this year and then a bigger chunk next year as we get more machines working. Those will be announced on our website.”

As HIVE 3D continues to find ways to scale its business model, there is a laser focus on the diminishing idea of the “American Dream,” where young families are able to purchase their first home. With the rising costs of supplies and labor, those families have been priced out of the market.

“That’s almost all we think about,” says Lankau. “Homeownership and that part of the American Dream is really struggling right now because the affordability gap between what the average person makes and what the average house on the market costs is just getting wider and wider.

According to Lankau, there are a lot of options to address the supply gap, but there aren’t an equal number of options to solve the affordability issue. Their goal is to find the best ways to deliver real cost savings over both traditional construction and other automated technologies.

“About three weeks ago, we kind of hit the inflection point in our current project where we printed a little house in three days. The cost of the house was what we wanted the cost to be, which is a disruptive amount less than what you could do traditionally or with any other construction technique. And we said, okay, now we're far enough along. We have this system. It's a scalable system. So, we're right now putting some capital together to go out and buy, build more of these machines and get out and start doing these truly affordable housing projects. Because that's where our heart is. Our heart's on the affordable side.”

HIVE 3D’s project in Burton, Texas isn’t available for sell yet, but it will be listed on Airbnb for interested customers to go and experience when it’s completed.

Additionally, the Casitas units in Round Top will be short-term rentals for festival patrons.

“We’ll go directly to market with our next projects,” says Lankau. “And then we'll sell that big house property in Burton at the end of this year.”

Rice University's top innovation exec leaving for new role at UVA

moving on

Paul Cherukuri, Rice University's top innovation executive, responsible for some of Rice’s major innovative projects like the Rice BioTech LaunchPad and Rice Nexus, will leave the university next month to accept a position at the University of Virginia.

Cherukuri, Rice’s first vice president for innovation and chief innovation officer, will become the University of Virginia’s Donna and Richard Tadler University Professor of Entrepreneurship and the school's first chief innovation officer, according to a release from Rice. Cherukuri, who has served for more than 10 years at Rice, plans to depart his current position on Sept. 30.

Adrian Trömel, associate vice president for innovation strategy and investments at Rice, will serve as interim vice president for innovation and chief innovation officer after Cherukuri departs, and as the university starts an international search for his replacement.

“We appointed Paul to build an ambitious and high-functioning innovation operation, and he has succeeded remarkably in short order,” Rice President Reginald DesRoches said in the release. “In every area, from technology translation and startup creation to commercialization and entrepreneurship training, he has led the effort to vastly improve our structure, operations and relationships. He has contributed immensely both to our strategies and their implementation across numerous areas, and we’ll miss him greatly.”

Cherukuri is a physicist, chemist and medical technology entrepreneur, and has been a member of DesRoches’ leadership team since 2022. Cherukuri served as executive director of Rice’s Institute of Biosciences and Bioengineering from 2016 to 2022, where he helped in the development of interdisciplinary translational research partnerships with federal and corporate agencies. His work helped earn nearly $37 million in funding for accelerating the development of new technologies into commercial products. In the energy transition field, Cherukuri led a $12.5 million partnership with Woodside Energy to transform greenhouse gases into advanced nanomaterials for next-generation batteries and transistors.

Initiatives the Rice Biotech Launch Pad, an accelerator focused on expediting the translation of the university’s health and medical technology; RBL LLC, a biotech venture studio in the Texas Medical Center’s Helix Park dedicated to commercializing lifesaving medical technologies from the Launch Pad; and Rice Nexus, an AI-focused "innovation factory" at the Ion; were all launched under Cherukuri’s leadership. With his work at the Ion, Cherukuri also led the announcement of a partnership with North America’s largest climate tech incubator, Greentown Labs.

“I am proud of the relentless innovative spirit we have built for Rice in Houston and around the world,” Cherukuri said in the release. “I look forward to bringing new energy and vision to UVA’s efforts in this critical space for our country, its success and future.”

UH scientists develop new flood scale for Houston weather resource

Weather Warning

One of the selling points of Houston's Space City Weather (SCW) blog and app has always been its hype-free forecasts. Meteorologists Matt Lanza and Eric Berger inform and soothe the 5 million annual visitors to the site in search of information about the latest weather events around Houston — without hyperbole.

But when severe weather alerts happen, how can SCW reach people in the Greater Houston area in such a way that they know it is time to take action and seek shelter? And when they do, will people understand the best actions to take?

To communicate information with the proper sense of urgency, SCW partnered with University of Houston Professor of Psychology Steven Paul Woods and doctoral student Natalie C. Ridgely to test out the effectiveness of messaging and a new flood scale.



“My lab does work on how people access, understand, and use health information, so I thought we could adapt some of that ongoing work and our expertise in psychological science to answer questions about weather communication, and help keep Houstonians informed and safe,” said Woods.

Woods, Ridgely, and their team recruited 100 Gulf Coast residents for a study and then presented them with weather forecasts that ranged in severity. One group reviewed the previous flood scale model used by Space City Weather that Lanza and Berger felt wasn't conveying enough urgency and information, and another reviewed a new enhanced scale that focused on predictive consumer behavior.

By framing the flood scale in terms of what people should expect to do (fuel vehicles, identify safety routes, etc.), they noticed users were more likely to actually perform preparations.

"People in the weather-protective cue group did a better job of planning for the storms,” said Woods. “We were able to improve flood-protective plans for the people who were at greatest risk of being unprepared.”

SCW has already implemented the new scale on its site as Houston moves further into Atlantic hurricane season. This change will hopefully fulfill SCW's goal of giving residents access to clear information to help them make safety decisions regarding the weather. Each entry on the 1-5 scale offers a simple checklist of safety behaviors, from encouraging the monitoring of emergency frequencies to preparing to move to higher ground. It's simple, but in disastrous situations, sometimes people need to be reminded clearly of simple tasks.

“Frankly, it feels great to be able to expand the Space City Weather Flood Scale to help people take action,” said Lanza.

“One of my biggest concerns about the scale was that we came up with it ourselves, which is fine in a vacuum. But as a scientist, I wanted us to make sure we were pushing out something that was adding value to storm prep, not adding confusion. Does it pass the test of being meaningful and scientifically sound? And who better to help solidify that than an expert in psychology?”
