n an Interview with Stock-Sector, John Rice, CEO of Sigma, Explains How Sigma’s Technology is Essential to a Manufacturing Revolution Known as 3D Printing
SAN DIEGO, CA / ACCESSWIRE / October 23, 2017 / CEOCFO Magazine, an independent investment publication that highlights important technologies and companies, today reports on an interview that Stock-Sector conducted with John Rice, CEO of Sigma Labs, Inc. (SGLB).
Based in Santa Fe, NM, Sigma has developed a key technology for a revolutionary form of manufacturing known as 3D printing or additive manufacturing, which can be used to make everything from high-tech airplane parts to artificial hips.
In the interview with Stock-Sector, Rice described how, in the traditional approach to manufacturing, “People take a block of metal, put it in computer-controlled milling machine, and cut pieces off the metal to get the shape they want,” he said.
In contrast, 3D manufacturing builds parts up layer by layer. “With 3D or additive manufacturing, you take material and melt it into the shape you want,” explained Rice. “It is really sculpting a part – making that part grow on the plate by melting layer by layer to get the exact shape required.”
The benefits of this approach are huge. With 3D manufacturing, it’s possible to cut the weight of a part by 40% or more, which is obviously crucial for airplanes and rockets. Yet at the same time, the cost of the part can cut by 40% or more, said Rice.
But despite the promise of 3D manufacturing, companies that have tried it have discovered a serious problem, as Rice also described in a previous interview with CEOCFO magazine. Tiny variations may occur in how the layers are laid down, so it’s very difficult to ensure that every part meets the exact design specifications and has the required high quality. Companies have found, in fact, that a majority of the parts they made fail quality control tests.
Sigma’s innovative PrintRite3D® technology solves this problem. “We put probes and sensors into the 3D machine and monitor the quality of the part in real time as it is being built,” said Rice. “That enables to know that each layer is compliant with their standards.”
Rice said that Sigma’s technology is now being tested by high-tech aerospace companies like Siemens, Woodward, Pratt & Whitney, and Honeywell Aerospace.
“Our dream is that we want to be the ‘Intel inside,'” said Rice. “We want every 3D manufacturing machine to have our little logo, Sigma Inside.”
At the same time, Sigma is looking to acquire companies to expand its offerings in the larger world of 3D manufacturing, said Rice. “What we aspire to do is make Sigma the digital channel in the marketplace, from design to quality assurance to the delivery of perfect parts.”
