Despite being at the forefront of digital fabrication technology, 3D printing is still shrouded in mystery, something which the Design Exchange (DX) hopes to change with its most recent exhibition, “3DXL” in Toronto. Curated by the director of DX, Sara Nickleson, 3DXL brings together 3D printing projects from across fields, including work from medicine, design and architecture. As the name suggests, the exhibit presents 3D printing on a scale not normally observed by the public. In particular, the exhibit addresses the role 3D printing will play in the future of architecture, and how it may begin to replace more traditional architectural construction.
