RIC Technology last week debuted its most advanced and largest construction robotic 3D printer, named RIC-PRIMUS. With the capability to print three-story structures up to 32 ft. tall, RIC-PRIMUS expands upon the innovations of its predecessor, RIC-M1 PRO.

“RIC-PRIMUS is a monumental step forward for the 3D construction industry toward real commercialization,” said Ziyou Xu, founder of RIC Technology and chief architect of the Robotic Construction Program. “Its expanded printing capacity makes it possible to build larger-scale construction faster and cheaper, unlocking new possibilities for 3D printing in both residential and commercial projects.”

In 2024, the company’s previous model, operated by Alquist 3D, printed an 8,000-sq.-ft. (743.2 sq. m), 20-ft. (6 m) tall Walmart extension. Walmart has planned another 200 projects utilizing RIC’s robots, which are expected to begin construction in February 2025. RIC Technology said it plans to meet the growing demand for faster, cost-effective, and sustainable construction systems.

The Fontana, Calif.-based company specializes in robotic construction using 3D printing. RIC said its proprietary technology can significantly reduce cost, time, and labor while enhancing productivity. The company’s suite of services includes robotic 3D printing, architectural design, tailored material solutions, and expert training and support.

RIC-PRIMUS reaches new 3D printing heights

RIC-PRIMUS boasts a printing height of 32 ft. (9.7 m), an 85.4-ft. (26 m) printing length, and a 36.1-ft. (11 m) printing width. This is nearly double the dimensions of its predecessor, RIC-M1 PRO. This size enables the robot to construct three-story residential buildings and wall systems, pushing the boundaries of 3D construction for both residential and commercial projects, said RIC Technology.

In addition, the upgraded system features enhanced mobility and speed. A 200 mm/s (7.8 in./sec.) printing speed and eight degrees of freedom allow the robot to print around rebars and against existing buildings or walls.

Like RIC-M1 PRO, RIC-PRIMUS features a compact and modular design, requiring no assembly and becoming operational within two to four hours. The automation reduces the need for skilled labor from three operators to two, further improving efficiency and cost savings, RIC claimed.

RIC Technology works with multiple materials, partners

RIC-PRIMUS includes an integrated self-loading ⅜ aggregate mixer pump that is adaptable to most industry-standard mixer pumps. This allows it to print with both concrete and mortar from most material providers. The company said this flexibility in materials enables large-scale, durable structural builds while retaining the precision needed for smaller, detailed projects.

RIC Technology also noted that RIC-PRIMUS is equipped with a real-time material quality control system to minimize human error, improve printing accuracy, and ensure consistent structural integrity.

In collaboration with Alquist 3D, Cement Masons & Plasterers Local Union 528, and SKAPA, RIC Technology’s robots will live-print structural wall segments at World of Concrete (WOC) 2025 using 3D material provided by Spec-Mix.

This will offer attendees a firsthand look at RIC’s latest robotic construction innovations. The event for the concrete and masonry construction industries will be from Jan. 21 to 23, 2025, at the Las Vegas Convention Center.
