Technology & Products

Key Products

Autonomous Robotic Construction System (ARCS) for 3D printing concrete houses and commercial structures.

Technological Advantage

Proprietary ARCS gantry-style automated 3D printing system capable of on-site construction printing with extreme efficiency (48-hour print time for 1,900 sq ft structures), requiring only 3 workers instead of traditional large crews, reducing labor costs by 50-80%, minimizing material waste through precision extrusion (30-60% reduction), and enabling construction of complete structural elements including footings, foundations, walls, and slabs in a single continuous process.

Differentiation

Value Proposition

Dramatically reduces construction costs and time while improving worker safety and sustainability - 3D printed homes require as few as 3 workers (up to 41% of total construction), reduce labor costs by 50-80%, minimize material waste by 30-60%, and achieve 48-hour print times for entire building structures with costs as low as $6,000 in materials for a 1,900 sq ft home.

How They Differentiate

SQ4D differentiates through its proprietary ARCS (Autonomous Robotic Construction System) gantry-style on-site 3D printing technology capable of printing complete structural elements including footings, foundations, slabs, interior/exterior walls, and insulation in a single continuous process with extreme efficiency (48-hour print times). Unlike competitors using modular/off-site approaches or requiring large crews, SQ4D operates with as few as 3 workers, reducing labor costs by 50-80% and material waste by 30-60%.

Why this company matters

SQ4D is a construction technology company based in Patchogue, New York, that develops on-site concrete 3D printing systems for residential and commercial buildings. Founded in 2017, the company focuses on reducing construction costs and timelines through its proprietary Autonomous Robotic Construction System (ARCS), a gantry-style printer that extrudes concrete layer by layer to form complete structural elements including footings, foundations, walls, and slabs in a single continuous process.

The ARCS system requires as few as three workers to operate, compared to traditional crews, and can print a 1,900-square-foot home in approximately 48 hours. SQ4D reports that this approach reduces labor costs by 50-80% and material waste by 30-60%, with material costs as low as $6,000 for a home of that size. The company targets residential home builders, commercial construction firms, real estate developers, and affordable housing organizations.

SQ4D achieved several industry firsts: the world's first legally permitted 3D printed home for sale in the U.S. (February 2021) and the world's largest permitted 3D printed home at 1,900 square feet (2023). The company partnered with Habitat for Humanity of Long Island to build a predominantly 3D printed home in Brentwood, New York, completed in 2024-2025. Its ARCS robot was inducted as the first robotic member of the Long Island Builders Association in December 2022.

SQ4D competes with ICON and COBOD International in the construction 3D printing space. Its differentiation lies in the fully on-site, single-pass printing of complete building structures, including foundations and insulation, without requiring off-site prefabrication or large crews. The company filed an exempt offering to raise $20 million in equity in September 2023 and operates with a team of 11-50 employees.
