In this episode of The Dwayne Kerrigan Podcast, Dwayne sits down with Jim Ritter, founder of Printed Farms and the man behind the world’s largest 3D-printed building. Jim’s story is one of relentless innovation—pivoting industries later in life, solving real-world housing problems, and challenging outdated construction methods with cutting-edge robotics and 3D printing technology.

From the challenges of curing concrete in extreme heat to the economics of large-scale printing, Jim reveals what it really takes to make 3D-printed housing viable. He explains the logistical nightmares of early machines, why cement isn’t the perfect print material, and how his team has built a new system to solve industry problems.

This is more than a conversation about construction—it’s about innovation, adaptability, and the future of housing.

Jim Ritter is a lifelong horseman, entrepreneur, and innovator. After decades competing internationally in show jumping and developing equestrian properties in the U.S. and Sweden, he turned his focus to real estate and advanced construction. In 2019, he founded Printed Farms, the company behind Florida’s first permitted 3D-printed home and the world’s largest 3D concrete printed building. Today, Jim continues to pioneer new patented printing systems through his latest venture, CASPER, shaping the future of construction technology.

Notable Quotes

• “It’s what you don’t know that hurts you the most. If you know something and you don’t mitigate for it, well then you’re just stupid.” – Jim Ritter
• “Innovation always starts small, and then it catches on. That’s how every industry evolves.” – Dwayne Kerrigan
• “We need structures that can withstand climate events. We can’t stop them, but we can build smarter.” – Jim Ritter

Key Takeaways

1. 3D Printing is Not a Gimmick – It’s about solving real housing shortages with scalable, resilient solutions.
2. Economics Matter More Than Hype – Printing walls in a day is possible, but the real costs lie in logistics, labor, and setup.
3. Innovation Meets Necessity – Climate change, labor shortages, and housing demand are driving the adoption of robotics.
4. Early-Stage Industry – With fewer than 500 printed houses worldwide, the sector is still young—but poised for explosive growth.
