Unream is a daytime artifact and a night lamp made by multi-material voxel 3D printing. Covered by lenticular lenses, the object shows dynamic colors in different viewing angles. When walking past the object, it looks like a digital screen with ambient animation. With unream, we reimagined the relationship between human, space, and objects. We propose to get away from static surface in object and industrial design, expanding binary material presence to dynamic material experience. With multi-material voxel 3D printing and our computational workflow, we can manipulate the optical effect of any material surface, embedding dynamic information into the object.
