NDT Company Launches High Energy CT Inspection Service

Industrial CT analyzes the complex internal structures of 3D-printed metal parts.

Quality is an important consideration in any manufacturing process, but with additive manufacturing, new factors come into play that simply aren’t major concerns in conventional machining. When you receive a block or billet of material for machining, certain assumptions can be made about the metallurgical qualities of the metal, from the crystal structure to its internal stresses.

With metal additive manufacturing, especially powder-based technologies, everything from part design, to powder quality to build conditions can introduce variables in the quality of the material. On top of this, destructive testing may not be desirable for an additive-based production process. With the internal geometries possible in 3D-printed parts, being able to see and scan the entire structure is valuable. One way to do this is with industrial CT scanning.

High-Energy Industrial CT Scanning Service

Jesse Garant Metrology Center recently announced the launch of its new high energy industrial CT scanning service. With this system, the company will be the only private lab in the world to provide this specialized inspection service. The new capability is an option for non-destructive testing and support innovation within advanced manufacturing.

According to Jesse Garant Metrology Center, the system is the first of its kind to pair a 3 MeV cone-beam x-ray source with a large format 2k x 2k flat panel digital detector. It will be able to accommodate rapid inspection of mid-size parts, up to 44.5 inches (1130mm) in diameter by 63 inches (1600mm) in height. The new capabilities will also directly support the growing additive manufacturing industry, allowing for feasible internal inspection and validation of 3D-printed parts made from ferrous and non-ferrous materials.

The company aims to expand the applicability of industrial CT technology to various part sizes and densities. This will allow for internal inspection and dimensional validation of 3D-printed parts that would otherwise go into production without proper inspection. The technology will also provide useful analyses for additive manufacturing, including identification of defects like porosity, residual powders, first article inspection, wall thickness variations and actual to nominal comparisons for out of tolerance features.

System Provides New Opportunities for Complex Part Designs

“We’re helping manufacturers qualify and validate parts that either weren’t possible because of limitations with existing technologies or weren’t feasible because the service was too costly or took too much time,” explained Jesse Garant, president of the center.

The costly endeavor required a $4.5 million investment in technology as well as three years of planning, design, development and construction to reach full operation. The new system required sourcing from both local and international manufacturers, vendors, and specialists, including the construction of the largest 1m x 1m (3.28’ x 3.28’) flat panel detector in the world.

With federal operational permits currently in place, the new system is now live. Jesse Garant Metrology Center is currently taking on orders from companies who wish to access this innovative technology during the system’s ramp up period.
