Medicine to manufacturing: Nano is the next frontier in 3D printing

Nano-level 3D printing can have various uses in medicine, like growing tissue cells to regenerate organs. Nano robots in bodies can attack cancer cells

Creating large structures with three-dimensional (3D) printing tends to get a lot of attention. Now, the breakthroughs are occurring at the nano level. The versatility of the technology is such that nano-level printing is witnessing impressive innovations.

Much of the innovation is being done in collaboration between industry and academia. The California Institute of Technology, or Caltech, has announced impressive work in this field. Caltech said in a statement that last year it had developed a new fabrication technique for printing microsized metal parts that are as thick as three or four sheets of paper. “The team has reinvented the technique
