An Iranian-born, US-based artist who uses 3D technology to recreate artefacts destroyed by Isil was among the speakers at the heritage organisation CyArk’s recent conference in Berlin on digitally preserving the world’s heritage. Material Speculation: Isis is an ongoing project by Morehshin Allahyari that uses digital tools such as ZBrush to create 3D models, which are then 3D printed. Each sculpture contains a memory card and flash drive with all the data used to create it. “I think of them as time capsules,” Allahyari said. “Every time someone 3D prints one of these artefacts, they take back the power that Isil was trying to take away.”
