Alquist

Alquist 3D is a construction technology company headquartered at 617 6th St, Greeley, Colorado 80631, USA, founded in 2020 by Zachary Mannheimer (Founder & Chairman), with Patrick Callahan serving as CEO. The company uses large-scale robotic concrete 3D printing systems to manufacture affordable housing, commercial structures, and infrastructure. Alquist's flagship robotic system, the A1X, is a robotic arm-based concrete printer mounted on a modular rail system that lays down inch-thick concrete layers at 200mm/s and supports structures of theoretically unlimited X and Y dimensions.

The A1 model is a complementary system deployed in education and workforce programs. Alquist moved its headquarters from Iowa City, Iowa, to Greeley, Colorado in 2023, receiving over $4M in municipal support from the city of Greeley. In 2025–2026, Alquist struck a landmark commercial deal with Walmart to 3D-print more than 12 commercial retail expansion projects across the United States—the largest-scale deployment of 3D-printed commercial building technology in U.S. history.

As of early 2026, Alquist had sold 14 A1X robotic concrete printers through distributors including Hugg & Hall and FMGI. The company has also partnered with Aims Community College in Colorado to develop the nation's most comprehensive 3D construction printing curriculum, training the next generation of construction robotics operators. The first completed Alquist home was built in Williamsburg, Virginia, in partnership with Habitat for Humanity, becoming the first 3D-printed owner-occupied home in America.
