Excuse the lack of technical vocabulary (I'm a teacher), but the impression I get is that PrintRite inspects the conditions under which defects may occur, so that the # of parts inspected post build is reduced, saving cost/time. I could be totally wrong and they already have the control aspect down- I know they've done it in past work, at least that's what it looked like from their published papers comparing welds... but if PrintRite itself is a standalone machine- and there's no magic control arm involved, it's a highly sophisticated program with a monitor, based on the image of the machine that's on the site. Am I wrong? (It would be 10x more awesome if I was!)

I would just very much hate for claims to be made about it that aren't true, because that would be more destructive to the share price in the long run if they're debunked... you may want to call the company to confirm. They're very easy to get ahold of. I called Valerie Vekkos on a Saturday and Cola and the rest were all in the 'press a number' menu. Just throwing it out there.

It would be far from useless. I would assume that once the compromised environment is detected the action would already be complete which would make a simultaneous correction impossible. The way that deviations in the aerospace industry work is more complex that most realize. Any small deviation can disposition the entire assembly as scrap, hundreds of thousands if dollars down the drain because of a .010" deviation. If the deviation is deamed repairable most times the proposed repair must be submitted to the end user and await engineering approval. It is not as simple as "fix the weld".

The PrintRite3D technology will be useful in many ways. I'm sure that in the future when additive manufacturing is introduced to the larger complex assemblies this real time feedback software will allow the immediate halt of production on a deviated part, rather than waiting until the entire process is complete only to realize at final inspection that the part is scrap. This alone will save countless hours of labor and materials. Not to mention the piece of mind to be able to go back to the data and find the root cause and corrective action.

What the PrintRite3D system will accomplish is already being done in traditional manufacturing by the human eye, x-Ray, and penatrant inspection after the welds and machining are complete. Only PrintRite3D will perform these inspections "on the fly" per say. That is a huge reduction in cost and lead time.

I have worked on the Aerospace industry for 10 years and I forsee that additive manufacturing and automated industry/government approved inspection processes such as PrintRite3D will revolutionize the industry.

I have a stock position with SGLB and I am in it for the long haul. I am very grateful that I came across this company during my research of the future of additive manufacturing.

They DO have a patent on it... so it doesn't really matter if that aspect isn't part of the current offering. United States patent laws do not require you to have a prototype in order to apply for a patent, all that is required is that you be able to describe the invention so that others could both make and use it, which they did.

That's why they are both integrating their software with others' machines, AND working on their own 3D printer, because they hold the intellectual property rights to the whole process. It would be stupid to just give your tech away if someone else could achieve the same result legally. That's why they envision the "Intel Inside" model.
