Want to 3D print your next home? It’ll take you 220 years to finish

Have you ever wondered how long it would take to print a house? Brick by brick it would take more than two centuries, according to one equation.
These days, 3D printing is everywhere. From charms and tchotchkes to guns and even body parts, the automagical thing-maker is opening up programmers and designers to new ways of developing their products.

Perhaps it’s only a matter of time before 3D printing spreads to real estate. The blog arm of real-estate search site Movoto did some number crunching, and concluded that it would take a single MakerBot Replicator 2 about 220 years, four months and 11 days to finish the bricks required for a standard two-story, 2,500-square-foot house. And it would cost $332,820 in plastic.

Movoto blogger Randy Nelson came up with the equation by timing how long it took a Replicator 2 desktop printer to build a single brick measuring 8 x 3.5 x 2.75 inches. From there, he extrapolated how many bricks a standard house would require, and multiplied that number by the time – 2.9 days per brick. The reason each brick takes so long is because of its density. Unlike standard 3D printed objects, which are often hollow or rely on geodesic design to keep production time down, each brick in this hypothetical hosue is completely solid and built with the Replicator 2′s .225 millimeter detail setting.
