I don't believe what is shown in the video, several flaws stand out. First the wrench is "scanned" with a hand-held "scanning device" and as the person using it describes how it scans to '"40 microns" or something like that you can see his hand and the scanner moving unevenly. Also the wrench is a 3D object with several pieces, machined to fit and move within each other. That in itself proves that this video is a fake. I suppose if each individual part was reproduced in a similar device it would work. I would have to see it live to believe it.
I may be showing my age but I'm with John on this one. How can a scanner "print" components it can't see? This 3D printer became unbelieveable when it produced a working copy. It was fun to watch though.
We bought a 3d printer before the end of the year. It prints ABS plastic parts. Its fast and cheap! In many cases the parts can be used and not just for show. I cant believe how strong the parts are. It takes about 10 minutes to learn how to run it. In most cases I can print and ship the same day. Boy,I could have used this a long time ago!
Believe it guys, it's real. We have a few of these at work, one sits about twenty feet from my office. It is a form of rapid prototyping, laying down plastic in an additive process. The second video looks like it was sped up 1000 times, because the models do take a while to produce. We use it when designing new parts so we can see how things interface, and also use it to make small scale parts to show at product shows.
