X-Ray Microcomputed Tomography in Additive Manufacturing: A Review of the Current Technology and Applications Micro-CT is especially useful and accurate for dimensional measurement and porosity analysis of parts that are additively manufactured. This review looks at the methods used to apply micro-CT technology to additive manufacturing (AM), including new and specialized applications …
Micro-CT has become widely used to analyze and test additively manufactured parts, particularly for porosity analysis and dimensional measurement. In conventional manufacturing, a weld would always be inspected for voids and inclusions, but in additive manufacturing the entire sample is essentially one large weld. Therefore, to qualify and verify safety-critical aerospace, automotive, …
Fiber characterization and orientation analysis Fibrous structures occur frequently in both natural and synthetic materials. With micro-CT, it is possible to analyze individual fiber properties (such as diameter), and orientation distribution. With several software tools, in-depth geometric characterization of fibers is possible. “The interface between fiber and matrix material in composites and …
Fiber-reinforced plastics (or polymers) are composite materials made of a polymer matrix that is reinforced with fibers. Typically, most of these composites have strong, stiff fibers in a matrix, which produces a component that often has a low density yet is strong and stiff. Fibers, such as glass (as in fiberglass), carbon, …
Comparison of medical and industrial X-ray computed tomography for non-destructive testing Industrial micro-CT scanning is a laboratory-based non-destructive testing technique used in a variety of applications for samples ranging from 1mm to typicallty about 300mm in diameter. Micro-CT scanners are used for industrial non-destructive testing due to the superior resolution possible compared …
Closure systems for glass vials containing parenteral pharmaceuticals are critical for protecting the contents against microbial or other environmental contamination. The most common closure system consists of an elastomer stopper held in place by a crimped aluminum band. Compression is applied during the sealing process, which can affect the closure integrity. We …
Modern Forensics Reveal Gruesome Details Of King Richard III’s Death ABSTRACT Richard III was buried in haste in 1485 after he was killed in battle and the whereabouts of his remains were unknown for centuries. In 2012, a skeleton was excavated from the former site of the Church of the Greyfriars in …
One of the most intriguing and historic forensic examinations of a human skull was that of King Richard III’s, the last king of the House of York and the last of the Plantagenet dynasty. King Richard III’s death in the final battle of the Wars of the Roses marked the end of …
Insights into manufacturing techniques of archaeological pottery: Industrial X-ray computed tomography as a tool in the examination of cultural material ABSTRACT Using micro-CT is becoming increasingly valued in archaeological ceramic studies because of its non-destructive nature and ability to provide valuable data and interior images. Of particular interest is the use of …
Precious artifacts and historical art objects are often affected by decay, environmental pollution, vandalism, or just simple age and neglect. Micro-CT is well suited to analyze historical artifacts for restoration and preservation, allowing conservators to inspect the exterior surfaces and interior structures without destroying the original objects. Unlike ordinary 2D radiography, …
