System CT Scans Large Parts in an Hour

New 3D computer topography (CT) part scanning system is said to scan up to 16 times faster than other CT systems. 

Jesse Garant Metrology Center (jgarantmc.com) has developed a new 3D computer topography (CT) part scanning system that is said to scan up to 16 times faster than other CT systems. The new system, which handles parts up to 44.5 inches in diameter and 63 inches in height, can scan parts in less than an hour, whereas existing technologies can require from 4 to 16 hours for the task.
 
The system is reportedly the first to pair a 3-megaelectron volt (MeV) cone-beam x-ray source with a large-format, 2k × 2k flat panel digital detector. 
 
The system can inspect parts and assemblies including castings, engine blocks, seat assemblies and carbon fiber chassis sections that can’t fit into cabinet-type CT systems. Conversely, it allows for scanning of larger lot sizes of smaller components. It also enables a cleaner separation of mixed materials and testing of materials too dense to scan with lower-energy systems.
 
The company said that its aim is to fill the gap in current inspection technologies that limit the application of industrial CT technology due to part size and density. This system enables internal inspection and dimensional validation of high-value parts that would otherwise go into production with less adequate inspection. The new capabilities will also directly support the growing additive manufacturing industry, allowing for rapid and viable inspection of larger 3D printed parts made from ferrous and non-ferrous materials.
 
Automotive manufacturers who use the company’s scanning service “will be able to quickly identify internal failures, speed up PPAP validation prior to production and efficiently inspect critical parts for high-performance applications,” promises company president Jesse Garant. 
 
The system is a culmination of a $4.5 million investment in technology and three years of planning, design, development and construction, including the construction of the world’s largest 1m × 1m flat panel detector.
