How INSPECT® works and why sales might take a while (but are sure to come).

The concept of Printrite3D® INSPECT® is to monitor the part build while certifying the process to form the baseline part. The software creates a "fingerprint" of the data for each layer of the build with a 1M fold reduction in size (raw data can also retained). They use this monitoring to create a reference (master) part for that machine. As subsequent parts are built, if a layer has defects, that layers abstracted data will not match the master "fingerprint"; indicating a suspect layer. This information gathering is achieved with off the shelf sensors so by applying the "fingerprint" concept to other sensors that measure plastic manufacturing etc. the technology is machine agnostic and should be portable to other materials.

The value of INSPECT® is in mass production runs. It's easy to see why sales could take some time, since the industry is only beginning to move from prototyping to mass production, but those sales will come.

If you haven't watched this classic, this should be considered required viewing for anyone with an interest in Sigma Labs...especially for the 2 minutes starting at about 19:30

GE, for instance, just recently signed a JTLA with Sigma Labs. They're one of the players in monitoring what's going on inside the equipment; and being able to tell if you are building a whole batch of these parts, if you are having a problem in any one of those.

With that in mind, know that In Process Quality Assurance® is a registered trademark of SGLB and they have patents for melt pool monitoring. Below is an article that discusses GE's use of what I have just described above.

GE Aviation, meanwhile, uses “in-process monitoring” during 3D printing to make sure parts meet the required standards. It discards any that fall outside acceptable parameters, and puts every third part through a scanner and X-rays it.
“That’s a huge part of the 3D printing technology,” a company spokesman says of this technique. “If you don’t have those, you cannot be sure of the parts you’ve made.”
Mr Reis insists that such techniques will in time allow manufacturers to satisfy regulators about safety. “We’re going to have more tools to do the testing faster and it will cause an acceleration of the penetration,” he says.

This is significant in that it allows them to reduce post build x-ray testing on 66% of parts.

Nothing has changed with this company. Only fear and a few impatient cold feet. SGLB has money in the bank and are solvent for the foreseeable future. Also, they have an additional revenue stream in producing contract parts that has just launched.

IMO...we're SAFE at worst, and FAT at best

Cheers!
