You are correct on the time required to build large parts. ExOne specs a minimum thickness of .1mm(.004") which could yield quite large build times, on the order of 2 hours per inch of thickness. Also, print precision is listed at .06mm(.0025") in the X/Y direction. In a lot of industries that would not be considered high precision so some post build machining might be required. All that being said, this is still exciting technology that is relevent now and will continue to improve in the future
Beth, I think you're right, that a tipping point is approaching all across the spectrum of these technologies, due to materials and processes. I also think the raised awareness of them and what they can do is also a big factor, and that's been boosted by the NAMII initiative and funding, as we mentioned in this article:

I have to agree that the 3D part printing world is getting pretty exciting, especially with developments like this. Anything that can shorten the time between concept to finished parts speeds up time to market and potentially improves the design by finding problems early in the design cycle. Thanks for profiling this industrial tool.
I'm not as familiar with what's happening on the higher end as that's your domain, but I'd concur big changes are happening on the low-end as well. Perhaps we're at a tipping point on both the high and low ends when it comes to advances both around materials and the ability to bring down price all leading to some very exciting times in the world of 3D printing.
Beth, that's a good summation, although much of the low-volume production parts used in high-end race cars and aircraft can no longer be considered experimental. I'd also emphasize that the higher end of the industry is on the cusp of some pretty big changes, due in part to expanding build volumes and better materials, as also mentioned in this recent article, "Biggest, Fastest Titanium 3D Printer: http://www.designnews.com/author.asp?section_id=1392&doc_id=251754
Chuck: With these higher end industrial printers, absolutely. With the lower end printers I've been writing about along with Ann, just starting. It's really a question of the quality/durability of the materials used and available and with the tolerances that the printer can handle. The manufacturers are making progress, but it's stil more experimental, in my view, than significant, widespread momentum. Perhaps Ann has a different view?
Ann and/or Beth: Is it common for engineers to use 3D printers to make serviceable parts? I had imagined that most of the applications we've seen until now were more about prototyping.
Beth, this machine is a different animal from most of the 3D printers you and I have covered. It's in the industrial class, along with some I wrote about from Paramount and EADS Innovation Works in my October feature, "3D Printing Flies High" http://www.designnews.com/author.asp?section_id=1392&doc_id=251526 Most of those use metal, since they're primarily aimed at aircraft components. This ExOne machine's capabilities include not only metals, but ceramics and glass, and its big brothers also use sand. It's for prototypes or short runs of multiple and/or custom metal parts in mining, automotive, and energy applications.
Ann, this is interesting, but how long does it take to make a part that would mostly fill the buiild volume. Some of the numbers I have heard in the past seem quite long. Those layers are very small, aren't they? For many shapes one could make them on a CNC machine much faster. Of course, there are some that are easier done with 3D printing.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
The government wants to study your brain, and DARPA wants to use similar information to give robots true autonomy beyond any artificial intelligence developed to date. Sound like science fiction? It's not.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
