Multi-material voxel printing creates products that animate themselves without power or screens.
A lamp that changes its appearance as you walk past it, displaying what looks like ambient animation, yet contains no batteries, no screens, no wires. Unream by Jiani Zeng and Honghao Deng achieved precisely this feat through multi-material voxel printing at MIT. The Platinum A' Design Award winning lamp embeds visual information directly into three-dimensional matter, assigning different optical properties to individual voxels (the 3D equivalent of pixels). During daylight hours, Unream reflects ambient light to produce shifting colors and patterns. At night, artificial illumination transforms the piece into something the designers describe as fantasy-like atmosphere. For brands seeking product differentiation beyond conventional finishes and textures, the implications deserve attention. Physical objects can now communicate dynamically through their material structure rather than through attached electronic systems.
The technical foundation combines lenticular optics (tiny lens structures that direct light based on viewing angle) with voxel-level material control. Traditional lenticular effects require flat surfaces and separate manufacturing of lens sheets and printed content. Unream integrates lens geometry and image content as a unified material structure, enabling dynamic optical effects on curved three-dimensional forms. Brand applications span multiple categories. Luxury goods manufacturers could create authentication elements revealing hidden patterns only from specific angles. Consumer electronics companies might develop housings displaying subtle visual shifts without power consumption. Premium packaging designers could produce unboxing experiences where bottles or containers appear to shimmer with internal motion. The computational workflow developed alongside Unream allows designers to specify color, transparency, and reflectivity distributions, creating material expressions previously impossible to manufacture.
Dynamic materials represent a genuine frontier for physical product design. When material structure itself becomes an expressive medium, the experiential gap between digital interfaces and physical objects begins to close. Brands investing in understanding voxel printing capabilities now position themselves to create products that communicate, respond, and engage in ways that static materials simply cannot achieve.
