ETH Zurich’s Block Research Group worked in collaboration with engineering firm Ochsendorf DeJong & Block and masonry specialist The Escobedo Group to bring the structure to life using expertly designed compression techniques. 399 limestone slabs were brought together after mapping out the technique on RhinoVAULT , a design plugin licensed by the group. Philippe Block and Tom Van Mele of the research group said, “Without any glue or mortar, with perfectly dry connections, this is really a milestone for stone engineering.” Related: 26 years, 9 tons of limestone, and a whole lot of love went into this magical fairytale house The Armadillo Vault spans 16 meters (about 20 feet), yet some sections are only as thick as five centimeters. Proportionally, the structure is half the thickness of an eggshell and remarkably strong. Each slab of limestone was left unfinished on the bottom side for time’s sake, creating an exterior resembling an armadillo shell and an underbelly of textured stripes. The intentional choice of finicky limestone demonstrates how the “relationship between geometry and forces” can be achieved with precision and respect for the materials. Once the Venice Biennale ends, the Armadillo Vault will be moved to a different location. Described as an “intricate 3D puzzle ” by the team, the structure can be disassembled and put back together while still maintaining its stability. +ETH Zurich Via  Dezeen Images via Iwan Baan , David Escobedo ,  Anna Maragkoudaki

Comments Off on Shapeways Debuts a New Flexible 3D Printing Material

3D printing technology just added a little spring to its step with a new maker material called “ Elasto Plastic ,” an off-white flexible polymer made by  Shapeways . The substance sports a grainy texture that retains its strength when used for large structures over 5mm. As an experimental material, it will not be available in Shapeways shops, but it will be available for purchase during a six-week trial that ends on July 9.
