A team of scientists at the California Institute of Technology, or Caltech, have discovered a way to engineer three-dimensional pieces of metal using nanoscale dimensions. What makes this feat unique is that these really small parts are impressively strong and durable despite having a structure that contains pores, grain boundaries, and impurities. These traits would be considered flaws or defects on other materials, but here it helps provide sheer strength that would be ideal for a wide range of applications including in the medical field, computing, and even space equipment.
