Following the 3D printing of villas and the 3D printing of a castle's eyes, 3D printed architecture has emerged as one of the most exciting and rapidly evolving areas in the 3D printing industry. While it's true that, objectively speaking, construction 3D printing hasn't seen major breakthroughs in recent years, this hasn't stopped entrepreneurs, engineers, and visionaries from diving into the field with enthusiasm. Everyone is eager to push the boundaries and make their mark in this promising sector.

Recently, Le Roux, a senior mechanical engineering student at Baylor University in Texas, unveiled a massive 8×8×8-foot concrete 3D printer he developed on his own. This isn’t just a concept or a theoretical idea—it’s a real, functioning prototype. Roux has built a large-scale 3D printer capable of reliably extruding layers of concrete. What makes this even more impressive is that the entire project was funded entirely out of his own pocket, without any external investment or institutional support.

According to OFweek 3D Printing Network, Le Roux will graduate this December. He has been applying the engineering and design knowledge he gained throughout his studies to test and refine this massive 3D 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, Roux believes there's still a lot of room for improvement through future iterations. In fact, he envisions using this technology to 3D print an entire house in the near future—something that may not be as far-fetched as it sounds.

"It looks really good in 3D, and it's not worse than other concrete 3D printers currently under development," said Le Roux.

"The money for this project came entirely from my own savings, and it has far exceeded my undergraduate budget," Roux explained. "The development cost of this 3D printer was around $2,500, but if it's 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, which should help reduce machine vibrations and improve overall stability. His goal is to build a more reliable and efficient system that can eventually be used for real-world construction projects.

Roux's story is a great example of how passion, creativity, and determination can drive innovation—even with limited resources. As 3D printing continues to evolve, we can expect more young engineers like him to push the limits of what's possible in the world of construction. Who knows? Maybe the houses of the future will be built by students just like Le Roux, right in their own garages.
