LLNL Researchers Use Direct Ink Writing to 3D Print Silicone Metamaterials with Shape Memory Behavior
A research team from Lawrence Livermore National Laboratory (LLNL) has used a direct ink writing (DIW) process to 3D print property-specific, silicone metamaterials that possess shape memory behavior, which technically makes them 4D printed. LLNL has worked with both 3D printed metamaterials and 4D printing before, but by using a DIW process, the material becomes more lightweight and functional, with a tailored, mechanical response.
