Building Houses With Robots: Tim Volkman On Australia's 3D Printed Homes Revolution | EC2026 #3
In this episode of Emeka Conversations, I sit down with Tim Volkman for a wide-ranging conversation about innovation, construction, entrepreneurship, education, regulation, and what happens when new ideas collide with systems that weren't designed to accommodate them. Tim is working on something that sounds almost futuristic but is already becoming a reality: using large-scale 3D printing technology to build concrete homes. His journey into this space came from years of experience in construction, engineering, and technology, and a willingness to question why we continue building the same way when better options are becoming available. We talk about what it actually takes to 3D print a house, how the technology works, the potential to reduce construction costs, and why Tim believes we could build stronger and more efficient homes using robotics and first-principles thinking. But technology is only part of the challenge. A major focus of our conversation is what happens when innovation runs into regulation, government approval, banking, and established industry practices. Tim explains some of the barriers he has encountered while trying to introduce a different way of building, including the difficulty of getting financial institutions to support homes built using new technology. We also go deeper into the culture that shapes how people think about work, education, risk, competition, and success. We discuss why schools may not be teaching young people to understand the "why" behind what they learn, how incentives can influence behaviour, and what happens when systems reward compliance rather than innovation. For me, this conversation goes beyond 3D-printed houses. It's really about whether we are willing to rethink the way we've always done things. If we already have the technology to build differently, what's stopping us? Topics explored in this episode include: • Tim's journey through construction, technology, and entrepreneurship • The development of concrete 3D printing • How 3D printing can be used to build houses • The potential to reduce construction costs • Innovation and first-principles thinking • Regulation and the barriers facing new technology • Why banks can be slow to finance innovative construction • The challenges of changing established industries • Administrative burden and productivity • Education, incentives, and the culture of achievement • Competition and why incentives matter • The future of construction and robotics • Why Australia needs to think differently about innovation If you appreciate long-form conversations that challenge conventional thinking and explore the people trying to build something different, follow the podcast and share this episode.
