Hi all,
The latest "wow!" video making the rounds on the internet recently is the 3-d printer clip on YouTube and other internet vid sources. In case someone hasn't seen it... a narrator takes us into a lab where the "inventor" shows the process whereby he takes a wrench, scans it in a new type of scanner, puts the printout into some sort of 3-d printer (after coloring the adjusting mechanism red) which contains some sort of "resin"material and after a few minutes the narrator reaches into the pool of "resin" and out pops a copy of a real working wrench with a red adjustment gear. The copy does the same job as the real wrench.
The narrator is a "real person"... a PhD and astronaut (at least according to several articles I Googled), but the whole thing has to be an elaborate hoax. Either that or it's the biggest invention since the light bulb. If it is a hoax, I have yet to see anyone write about it on any discussion group, on YouTube, or other news source. Likewise, a real invention such as this would have been heralded throughout the scientific world by now. Anyone have any explanation or comments?
