What is inside a Samsung S7 smartphone?

This case study is a quick but powerful demo of what X-ray CT inspection can do. The Samsung S7 used in the test is my own phone, 2 years old and not in use. This phone was released about the same time as the Samsung Galaxy Note 7 – which had battery explosions often. The …

View from the inside

This is a microCT image of the inside of a 3D printed metal lattice structure – the struts are 0.75 mm wide and rough as built by laser melting of metal powder.

Step by step microCT scan process

Here are some photos of a typical scan process, in photo steps: Step 1: Load the sample in some low density mounting material – the sample is a concrete of undisclosed origin, and the project will not be discussed here \ Step 2: load the sample into a rod or cylinder Step 3: open the …

Metal casting analysis

Metal castings typically contain porosity which can affect the strength and lifetime of the part. Excessive porosity can be reduced by optimizing the casting parameters, and the best way to do this is to visualize and quantify defect sizes by X-ray microCT. It is also possible to routinely check castings to ensure nothing changes in …

Medical implant testing

X-ray microCT is nondestructive and therefore is used for testing produced parts for porosity or inclusions (defects) and sometimes for wall thickness or deviation from CAD design. All these types of analysis can be used to assess a part before implanting it into a patient. We provided this service for a recent implant patient who …

Analysis of 3D printed parts

This example shows a typical microCT analysis of 3D printed parts. 3D printing and additive manufacturing technologies differ widely and quality control of these parts are very important. In this example, Markforged parts were scanned of the following types: 1. Nylon 2. Short fibres in onyx plastic 3. Long fibres in nylon Here is a …
