Engineers expand multi-material design possibilities with cellular fluidics

Engineering researchers at Lawrence Livermore National Laboratory (LLNL) have achieved breakthroughs in multi-material additive manufacturing (3D printing) through the power of capillary action. The LLNL team printed lattice structures with a series of custom-designed unit cells to selectively absorb fluid materials and precisely direct them into patterns, making it possible to fabricate complex structures with unprintable materials or materials with vastly different properties.
