Born from an effort to address rural housing challenges in Alaska, X-Hab 3D develops robotic 3D concrete-printing systems for construction. The State College company grew out of Penn State engineering, architecture, and additive-construction research, bringing together rugged mobile or fixed-site printers with compatible materials and design software for projects ranging from homes to infrastructure. Its systems have been tested in demanding settings including sub-Arctic Nome.
SQ4D LLCSQ4D builds full-size concrete homes, commercial structures, and infrastructure with its ARCS construction 3D printers. The New York company has marked the field with several permitted projects, including the first U.S. 3D-printed home for sale and a Habitat for Humanity home in Islip with more than half its structure printed, including the foundation, walls, and insulation. It also sells ARCS printers and provides education for builders entering construction 3D printing.PATCHOGUE, NY
Vitruvian BuildingVitruvian Building is an Athens, Ohio-based construction-technology company focused on using 3D printing to help communities create affordable, sustainable housing and infrastructure. Its work centers on making advanced building methods more accessible through the Scorpion construction-printing platform and related education for community participants.ATHENS, OH
PLYNTH 3D INCFounded by architect and technologist Peter Sepassi, PLYNTH 3D is developing a robotic system that prints high-performance building components from bio-based, fiber-reinforced wood. Its approach combines upcycled wood fiber with continuous reinforcement and large-scale robotic deposition, aiming to use harvested timber more efficiently while reducing embodied carbon. Sepassi previously worked at Bjarke Ingels Group and Shigeru Ban, and led design and technical strategy for the world’s largest 3D-printed housing development in Wolf Ranch, Texas.NEW YORK, NY
Xact Metal, IncFounded in 2017, State College’s Xact Metal makes metal powder-bed fusion 3D printers designed to bring laser-based additive manufacturing within reach of more manufacturers. Its first printer shipped in 2019, and the company now builds the configurable XM200G family, including a micro-printing variant, while developing the larger XM300G series. Based at Penn State’s Innovation Park, Xact Metal supports customers through a partner network spanning more than 40 countries.332117STATE COLLEGE, PA
