Lennar, the nation's second-largest homebuilder, has teamed up with ICON, a technology pioneer specializing in large-scale 3D printing, to "print" 100 single-story houses using a giant 3D printer on-site to lay concrete-based building material. 

Lennar Co-CEO Jon Jaffe recently stressed that the entire building industry faced shortages of materials and skyrocketing costs. To solve this problem, the company is turning to 3D printing: 

"Labor and material shortages are two of the biggest factors pushing the dream of homeownership out of reach for many American families. 

"Lennar has always expanded the boundaries of technological innovation to keep quality homes affordable, and 3D printing is an immensely encouraging approach," Eric Feder, president of LenX, Lennar's investment arm, said in a press release. 

Digital renderings of the 3D-printed neighborhood were released last week.
