Build what you want, when you want it, with what’s on site.
That’s the motto of RedWorks, one of the companies I mentored at LightSpeed. After becoming finalists at NASA’s 3D-Printed Habitats Challenge, they decided to take Earth as their beachhead market before moving onto Mars. RedWorks’ revolutionary manufacturing technology lets builders make masonry entirely on-site. RedWorks printers use local sources of dirt, dust, and sand to 3D print what builders need, when they need it with whatever is on-site, from a marketplace of materials created by architects and engineers.
