South Korean construction 3D printing manufacturer ‘3DPRIYOL’, group of experts in architecture, has perfected luxury department store designed by OMA. This 13-story building with total ground area of 150,000 sqm opened. The 3D printed Smart Joint System has benn chosen to realize world’s first commercial free-form curtain wall as it has solved expensive, time-consuming and unrefined traditional manufacturing system’s problem. 3D printing was especially the key to solve its geometric problem called ‘polygonal mesh face-offsetting problem’. 
3DPRIYOL and WITHWORKS have jointly designed and engineered non-repetitive 647 smart joints for the curtain wall of 4,600 sqm according to the shape of curtain wall. 3DPRIYOL has also adapted both existing manufacturing technology (iron casting) and additive manufacturing technology (binder jetting).
