DAVIE, Fla.—Sintavia, LLC, a provider of metal additive manufacturing (AM) services, has broadened its precision scanning and quality control services for critical industries by incorporating high-powered computed tomography (CT) scanning capabilities into its operations. Sintavia uses metal additive manufacturing to make parts for such industries as aerospace and defense; oil and natural gas; automotive; and ground power generation. The company’s high-speed printers are co-located alongside precision post processing equipment, a full complement of mechanical testing equipment, and a full metallurgical and powder laboratory that enable Sintavia to optimize parameters, serially manufacture, and audit quality parts for critical industries.
The company’s Nikon XTH 320 CT scanner offers porosity analysis and nondestructive examination of the complex internal networks of components produced by additive manufacturing. By adding an industrial CT scanner with multiple kilovolt (kV) X-ray sources, Sintavia becomes one of very few companies with the capability to confirm quality and ensure the material integrity of AM parts manufactured for aerospace and defense applications, the company said in a press release.
“Quality control is the number one reason Sintavia incorporated the CT scanner in our manufacturing process,” said Doug Hedges, Sintavia’s president and COO, in the release. “Adding this high-fidelity scanner to our comprehensive manufacturing and testing suite allows us to meet and exceed customer quality specifications.”
Sintavia’s industrial CT scanner features 225 and 320 kV microfocus X-ray sources that are used depending on the density of material and the resolution necessary to analyze internal passages and cooling channels. The 225 kV source is equipped with a reflection target creating a 3 micron spot size, which allows Sintavia (www.sintavia.com) to generate extremely detailed imaging for aluminum and titanium parts. The 320 kV source is used to penetrate through larger parts or higher density alloys, such as nickel alloys and stainless steel with high resolution and magnification, the company said.
