History
SQ4D was founded in 2017 as a construction technology venture focused on large-scale construction 3D printing for homes.[3]
In January 2020, the company completed construction of a demonstration residence in Calverton, New York, measuring approximately 1,900 square feet.[4][5] The project involved 3D printing the structure's foundation and walls using the company's ARCS system over approximately 48 hours of machine operation spread across several days.[3][6]
The following year, a 3D-printed house built by SQ4D in Riverhead, New York, was listed for sale as a permitted residential building[7][8] and received attention as one of the early 3D-printed homes to be offered on the residential market in the United States and to be eligible for a certificate of occupancy.[9][10][11] The property was built using a combination of 3D-printed concrete components and conventional construction methods for elements such as roofing and mechanical systems.[3]
In 2023, a newly completed home in Islandia, New York, was listed for sale as a 3D-printed residence.[12] The project involved a collaboration between a residential developer and SQ4D and included approximately 2,000 square feet of living space.[13][4]
Collaboration with Habitat for Humanity
In 2024, SQ4D participated in a construction project with Habitat for Humanity of Long Island in Brentwood, New York.[14] The project, which was Habitat for Humanity's first 3D-printed home on Long Island,[15] used construction 3D printing for more than half of the structure, including walls, foundation, and insulation.[16][14]
Technology
SQ4D's construction process uses a track-guided gantry system that extrudes concrete in layers to form structural walls based on a digital building plan.[7][5] Printed concrete elements are combined with conventional construction methods for roofing, mechanical systems and finishing work.[8][17]
