What SQ4D does

SQ4D LLC is a privately held construction-technology company founded in 2019 and headquartered in Patchogue, New York, that develops and deploys the ARCS (Autonomous Robotic Construction System), a gantry-style 3D printer that extrudes concrete layer by layer to construct footings, foundations, walls, and insulation for full-sized residential and commercial structures. The company differentiates on a patent-pending rectangular tangential nozzle, on-site concrete mixing using locally sourced materials, automated material calculation branded as Zeero Waste, subterranean printing capability (foundations and footings), and a high-compressive-strength mix averaging ~9,000 psi. Technology is offered alongside a VR home-design experience that lets buyers configure floor plans and finishes before construction.

SQ4D operates three revenue streams: (1) direct-to-consumer sale of completed 3D printed homes, priced from roughly $100K for small units up to $800K+ for large custom builds, with the first US 3D printed home for sale listed at $299,999 in Riverhead, NY; (2) sale and lease of ARCS 3D printers to builders and developers, with options for purchase, lease, joint venture, or subcontracting; and (3) ancillary services including VR home design. Target customer segments include individual homebuyers, licensed builders and developers, accredited investors (via private inquiry channels), and disaster-relief/emergency-housing use cases.

The company has delivered several "firsts" in the US market, including the world's largest permitted 3D printed home (Calverton, NY, January 2020), the first 3D printed home for sale in the US (Riverhead, NY, February 2021), and the world's first predominantly 3D printed home built with Habitat for Humanity of Long Island (Islip, NY, February 2025). Recent commercialization activity includes a partnership with 4Dify to develop California's first fully permitted 3D printed home community, expanded media coverage across CNBC, CNN, CBS News, Reuters, and Business Insider, and the launch of the ARCS 4.2 printer for builder reservation. SQ4D has 11-50 employees, no disclosed institutional funding rounds, and no public revenue figures.

Partnerships

Three partnerships are on record, tiered core, flagship and minor.

• Habitat for Humanity of Long IslandcoreStrategic or Co-development Partner · 20 February 2025Strategic partnership to build the world's first predominantly 3D printed home. Over 50% of the home (foundation, walls, insulation) was 3D printed using ARCS technology. The home in Islip, NY (Brentwood) was given to Carmen and Starky Cabrera, a family who previously lived in a cramped basement apartment. The Town of Islip provided a $250,000 subsidy. Habitat Long Island CEO Diane Manders stated the nonprofit is interested in using the technology for future homes.
• 4DifyflagshipStrategic or Co-development PartnerPartnership to develop California's first fully permitted 3D printed home community. Featured on CBS News Good Day Sacramento. SQ4D's ARCS printer and building approach combined with 4Dify's development capabilities to create scalable housing solutions for California's housing crisis and wildfire-prone areas.
• King Quality Roofing and SidingminorGTM or Marketing PartnerDonated the roof for the Habitat for Humanity 3D printed home in Brentwood, NY. CEO Jeff Brett noted the family's gratitude and the child's dream to hold game night in their new home.

Direct peers

• Mighty Buildings: Construction-tech company using additive manufacturing and a proprietary synthetic stone material to produce prefabricated, factory-built homes. Comparable to SQ4D in its goal of dramatically reducing cost and time for residential construction.
• WinSun (Yingchuang Building Technology): Chinese pioneer of large-format construction 3D printing using recycled and proprietary materials. Comparable in scale of structures printed and printer-as-product model.
• CyBe Construction: Dutch construction 3D printing company selling its CyBe MORTAR printers and printed-housing services. Competes in the same concrete-printing equipment and printing-as-service niche.

• COBOD International: Danish manufacturer of gantry-style construction 3D printers (BOD2) sold globally to builders and developers. Closest international analogue to SQ4D's ARCS hardware business model.
• ICON: Austin-based 3D construction technology company developing large-scale robotic printers (Vulcan, Phoenix) for homes and buildings. Most direct US competitor to SQ4D's ARCS system, pursuing similar D2C, builder, and developer channels.
• Apis Cor: US-based company developing mobile and robotic construction 3D printers and full home-printing services. Directly competes with SQ4D on construction-scale concrete printing.
• Black Buffalo 3D: US-based construction 3D printer manufacturer focused on structural concrete printing for residential and commercial buildings. Comparable hardware-led business model to SQ4D's ARCS sales.

Broad incumbents

• Caterpillar: Global heavy-equipment and construction-machinery incumbent that has invested in and explored autonomous and additive construction technologies. Represents the broader industrial-incumbent competitive set into which 3D construction printers must sell.
• PERI Group: Global formwork and scaffolding manufacturer that partnered with COBOD to offer 3D construction printing solutions. Established construction-industry incumbent whose printer offering overlaps SQ4D's enterprise builder channel.
