if they can hook that up t0 a fax machine you wouldn't have to stock any non metalic parts , that would be fantastic, it's amazing the new technology the keep comming up with

This process is called sintering, and has been around for some time now, but it is still way cool to look at!!!

It's not exactly sintering. Sintering is usually done in specialized furnaces. At my work we do this process for a number of things. We also do sintering for other products.

We are currently working on doing this in metal - start with a CAD drawing, hook to a special powder bath and end up making solid 3D metal parts.... It's pretty amazing..

I got that in an email the day before this thread started. Pretty neat!

It's created in MA, so it will be taxed into oblivion before it goes anywhere ....

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.

Here ya go... watch the video at the bottom.

The other issue is the distinct metallic sound when he placed the "new" wrench on the table. Looks to me like the old wrench with a new paint job.

Excuse me, I gotta go print me a new pump for the loader on my tractor.

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!

That thing is mint! I like the lack of rap music in the video too.

I didnt see the origonal video. It sounds like it was a hoax? Anyhow if you ever get an idea for a new product let me know I'll print it off for ya.

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.
