Volume Graphics Analysis Services

Porosity Analysis

We provide Volume Graphics
Analysis Services

In addition to our 3D CT scan services, Delphi Precision Imaging provides
in-house Volume Graphics Analysis Services.

Using Volume Graphics software, we can perform analysis services per our customer's direction, helping to obtain quantitative data that improves the efficiency and speed of their production processes.

Types of analysis included part-to-CAD comparison, part-to-part comparison, porosity analysis, dimensional measurements of internal details and reverse engineering for complex parts with hidden internal features.

CAD to Part comparison, with a CAD model overlay with the actual additive manufactured part.  The deviations are shown with color variations heat map

Part-to-CAD Comparison

CT scan data results are over-laid with the CAD model to create a color-coded 3D model showing discrepancies between the part and the CAD, internally and externally, helping customers determine if their part has been built as designed.

Parts that are subject to pre- and post-  stress. shock, vibe & heat treat testing can be CT scanned before and after. Using our part-to-part analysis, we overlay the CT scan data and detect and quantify resulting differences.

This is porosity inside a printed additive manufactured part. The size of the poristy is color coded for ease of visualization. CT scanning is used to find porosity.

Porosity Analysis

Advanced porosity analysis software allows for both quantifying and identifying the precise locations of porosity of a variety of materials including castings, additive manufactured and plastic molded parts.


Detailed advanced porosity analysis reports provide the percentage and volumes of porosities or inclusions in an entire part or a designated area of interest such as threads, thin walls or critical stress points.

This is a part that has been reverse engineered using CT scanning.  The internal and external surfaces are detected and translated into CAD surfaces.

Reverse Engineering

Our advanced computed tomography scanning services greatly reduces the time needed to obtain the measurements required to build a CAD model on parts with complex surfaces. Industrial CT captures internal geometries that other methods, such as laser CMM cannot.

Dimensional analysis using CT scanning.  internal dimensions are measured with x-ray CT technology and software metrology

Dimensional Inspection

Obtain GD&T measurements for both internal and external features with Industrial CT in a fraction of the time of traditional methods. Industrial CT also allows for obtaining data for complex internal features.

Carbon fiber composites that have been CT scanned to show warp and weave of the layup within the resin.

Composites Analysis

Industrial CT is a powerful tool for non-destructive inspection and analysis of carbon fiber parts. CT allows for locating the exact axis and point of porosity, resin voids and delamination within complex geometries inside of carbon fiber and composite parts.


Advanced analysis tools at Delphi Precision Imaging make the measurement of fiber orientation and the quantification of porosity and voids with detailed reporting.
