Built in 1938, Luxembourg’s Groussgasmaschinn, or GGM11, is touted as the world’s largest gas engine, and is, without a doubt, the biggest object we’ve ever scanned in 3D. At 26 m long, 10.5 m wide, and 6.5 m high, and weighing 1,100 tons, GGM11 is now an exhibit of the Luxembourg Science Center, whose team reached out to Artec 3D looking to preserve the engine in 3D. To take on a project as massive as that while making sure the engine’s valves, clamps, and other fittings come out crisp and accurate in the final 3D model, Team Artec brought two laser scanners in. The tripod-mounted Artec Ray was used to make submillimeter-precise panoramic scans from a total of 18 different angles, and the handheld Artec Leo was there to zoom in on specific sections featuring particularly small elements and areas obstructed by adjacent parts.
