The first patent that deals with a process much like 3D printing was filed by Johannes F Gottwald in 1971. He patented the Liquid Metal Recorder, (U.S. patent 3596285A), a continuous inkjet metal material device to form a removable metal fabrication on a reusable surface for immediate use or salvaged for printing again by remelting.
3D printing or Additive Manufacture has come a long way since then, with ever-expanding uses far beyond our imagination, and extending to scales beyond the purely desktop scale we are used to seeing.
Additive manufacture in the late 2020s played some role in almost every industry, from high performance medical applications to the conservation and architecture fields. Additive manufacture technology and processes were deployed from the smallest nano-scales to massive terraforming projects. As the investment grew, so did the use cases.
Two separate events in the US captured the imagination of the globe, pushing the limits of additive manufacture into bold new territory.
