Wall Thickness Analysis

Use Wall Thickness Analysis to measure and evaluate a part’s walled components and structural integrity. Identify defect areas, quantify thickness uniformity, and optimize material usage.

Overview & Setup

To use Wall Thickness Analysis, ensure you have the Integrity Analysis module activated in your organization. Running the analysis requires editor access in Voyager.

1. Click on the “Wall Thickness Analysis” button in the top panel to start workflow.
2. Select the volume you’d like to analyze. Note, you can run multiple wall thickness analyses in parallel. The processing time for a given analysis depends on the number of voxels in your full resolution volume. We advise narrowing down your region of interest (ROI) in order to reduce the number of voxels required in the analysis. Running on a full volume can take well over an hour, similar to other simulations, like finite element analysis (FEA) or computational fluid dynamics (CFD).
3. Adjust the threshold until you can clearly see both edges of the wall you wish to analyze in blue. If you've set the volume visualization to grayscale, the gray portion is the wall boundary in the scan. Matching the blue visualization to that boundary will provide you with the most accurate result. It is often most helpful to view the threshold in one of the 2D views. In a mono-material part, we typically recommend only adjusting the lower threshold. Increasing the lower threshold erodes more material from the analysis. Conversely, decreasing the lower threshold will include more material, increasing the relative wall thickness. For multi-material parts, adjusting the upper threshold can help isolate higher density materials in the analysis.
4. Once you have set your threshold, click “Submit” to process the analysis on the cloud.
   
   In this example, the blue threshold boundary does not quite match the gray wall boundary of the scan. Adjusting the lower threshold to a lower value will include more material and allow the threshold boundary to more closely match the wall boundary.

Viewing & Analyzing Results

Once the analysis has run, to view the results, click on the Wall Thickness Analysis object in the "Data Panel" on the left. It should be nested under its parent volume.

The colors shown on your scan represent the range of wall thickness measurements. You can adjust the visualization through the range map in the "Attributes Panel" on the right. Use the barn doors to enforce tolerance ranges or adjust the range limits below the map.

To download the resultant mesh and wall thickness results, scroll down in the "Attributes Panel" and click “download”. The mesh file (.PLY) and down-sampled CSV of the mesh vertices (x, y, z coordinates) and corresponding thickness results will be downloaded.
