Culmination of 4 additive technologies.

OK, this blog is not supposed to be about 3D printing or even additive technology. It's just so interesting. This post from Andy Baluchi sums up several techniques. I'll try to lay off the subject for awhile:

Hybrid Additive/Machining center prototype from DMG/Sauer

What got my attention here is the ability to add 3.5 kilograms of material per hour (20 times faster than laser sintering).

Have you seen this alternative to compressed air?

I saw one of these a few years ago on a large Mazak gantry, but this one is for smaller, enclosed machining centers:

Yet more 3D Printing

This is getting serious. When you see the Airbus hinge, you can see that machining that would be very hard. Saving weight in an airplane is EVERYTHING.

Thanks Greg.
