Correct, the BS about 3D Printing seems to know no bounds.
Right now 3D printing is going through the basics, learning how to put material down into a shape. It will advance by getting faster, and working at higher resolution.
Where it really gets exciting is when advancements in materials intersect with it. When 3D printing can deposit multiple advanced materials at high rez, you can begin to envision electrical conducting plastics and shape memory metals combining to produce artificial muscle that’s stronger and more durable than real, and communicates with the nervous system.
Metal matrix ceramics, carbon fiber, graphenes, fabulous material that will find new applications. Using different materials in the presence of catalysts, electrical current,or thermal energy will make chemical changes possible in place during the build up.
3D printing machines will “break out of the box” and take on the appearance of swarms of insects or rodents, building massive structure like aircraft wings, even buildings and bridges, working in huge coordinated teams like ant colonies or beehives.
3D printing machines might be sent to the Moon or Mars, to build the landing base before humans arrive.
This is the most potentially transformative technology since the invention of the microprocesser.
