3D printers are not replicators like in star trek .Even molecular assembler the use of nanotechnology to move or rearrange atoms are closer to replicators BUT still not replicators.Racecarlock said:https://www.google.com/search?safe=off&site=webhp&source=hp&q=%223d+printed+food%22
Sure, they're not that advanced yet because they're basically version 1.0 .
But guys, we have replicators. From star trek. This is amazing.
For there to be true replicators one must turn energy into mass and no where are engineers at that point any time soon.Even molecular assembler are probably 50 to 100 years out.
