Researchers at Mitsubishi Electric Research Laboratories (MERL) are experimenting with "5D" printing, or five-axis additive manufacturing. By using a build plate that rocks back and forth along two axes, a fourth and fifth axis are created, resulting in parts with curved layers that are, consequently, much stronger than conventional 3D printed parts. The MERL team proved this in a recent experiment that showed a 5D printed pressure cap could withstand nearly five times the pressure of a standard 3D printed cap. It's a complex process, the researchers say, but well worth it. Read more at 3DPrint.com: https://3dprint.com/139742/mitsubish...c-5d-printing/
