In recent years, 3D printing has captured the imagination of many, especially in the field of architecture. From 3D printed villas to the 3D printed eyes of a castle, the concept of 3D printed buildings has become one of the most exciting topics in the industry. Although the technology hasn't seen major breakthroughs yet, it continues to attract entrepreneurs, researchers, and students who are eager to push the boundaries of what’s possible. One such individual is Le Roux, a mechanical engineering senior from Baylor University in Texas. He recently unveiled a massive 8×8×8-foot concrete 3D printer that he designed and built entirely on his own. This isn’t just a theoretical idea or a prototype shown at a conference — Le Roux has actually created a functional machine capable of reliably extruding layers of concrete. What makes this even more impressive is that he funded the entire project using his own savings, going well beyond the typical budget for an undergraduate project. According to reports from OFweek 3D Printing Network, Le Roux graduated in December and has been applying his engineering knowledge to test and refine the printer. The machine features a wooden frame with a print resolution of approximately 0.75 mm and a current printing speed of 50 mm per second. However, he believes there is significant room for improvement through future iterations. In fact, he envisions the possibility of using the same technology to 3D print entire houses. “I think it looks pretty good in 3D, and it's not worse than other concrete 3D printers being developed out there,” Le Roux said about his creation. The total cost of the project was around $2,500, which far exceeded his initial budget. However, if mass-produced in the future, the cost per unit could drop to about $1,500. For his next version, Le Roux plans to switch to an all-metal frame to reduce vibrations and improve the machine’s stability and overall performance. His work highlights the growing trend of young innovators experimenting with 3D printing in construction, proving that with creativity, determination, and a bit of funding, the future of building could be reshaped in ways we’ve only begun to imagine.
