The Advanced Manufacturing Lab at Lawrence Livermore National Laboratory (LLNL) is continuing to make progress in the field of material design for 3D printing. In January, we covered the lab’s research into 3D printing microscopic trusses that resulted in a lightweight object with extreme rigidity. The 3D printing scientists and engineers at LLNL have now released a new study, titled “Three-Dimensional Printing of Elastomeric, Cellular Architectures with Negative Stiffness“, that delves into controlling the properties of foam materials.
Padding materials, like foams and gels, have their advantages and disadvantages.…
