Scan Inspection


Topics:

X5 and X7 users can inspect laser scans during or after a print job. Find the Scan Inspection page by navigating to the Part View page for that part and selecting a scan from the Scans section of the Details panel on the left-hand side of the screen, or by navigating to the Print Jobs page, selecting the Actions button to the right of the print job in question, and selecting View Laser Scans from the drop-down menu.

For more information on using the features on this page to measure part features during or after a print, see In-Process Inspection, below.

From left to right, the top of the page contains:

  • Visibility drop-down: This feature allows you to view or stop viewing different sections of the part. Click to load a drop-down menu containing the following toggle switches:
    • All Sections, Surface Boundary, Triangular Infill, Floor, Wall, Support Material
  • 2D/3D toggle buttons: Click one of the two options to change the scan model and the features of the box in the top right corner of the page accordingly.
    • When 3D view is enabled, the page displays a 3D model of the selected layers of the part, with visible surface boundaries outlined in blue and scanned layers indicated in gray.
    • When 2D view is enabled, the page displays the currently selected layer of the part.
  • Camera Mode icon: Click to view the laser scan or to see deviations in layer height for the selected layer. This option is enabled by default.
  • Line Measurement Tool icon: Click to measure a straight edge or distance on your part. Only enabled when in 2D view.
  • Rectangle Measurement Tool icon: Click to measure a rectangular block on your part. Only enabled when in 2D view.
  • Circle Measurement Tool icon: Click to measure a hole or diameter on your part. Only enabled when in 2D view.

The contents of the box in the top right corner depend on A.) whether 2D or 3D view is enabled, and B.) whether Camera Mode or one of the measurement tools is enabled.

  • When 3D view is enabled: The box, titled Print Job Scans, lists every scanned layer. Select a layer from the list to enable 2D view and load the two-dimensional scan of that layer in the center of the page.
  • When 2D view is enabled: The contents of the box depend on whether Camera Mode or one of the measurement tools are enabled. The title of the box reflects the selected icon.
    • Camera Mode box: Lists suggested actions for viewing the part with and without overlay. This mode is enabled by default when in 2D view. If you are currently viewing a scanned layer, the following option appears:
      • Scan Region: Click to generate a Z-height heat map displaying the distribution of data points and the standard deviation of heights across the selected layer. To rename the heat map, click and type within the Name field; note that this will change the name of the Scan Region option in the Camera Mode box.
    • Line Tool box: Lists instructions for using the line tool, with the current instruction to follow highlighted in green. After you have followed the instructions to add a line measurement to the scan, this box will be replaced by the Selection Mode box, which contains:
      • Name and length of the line measurement
      • Remove Measurement button: Click to remove the line measurement.
    • Rectangle Tool box: Lists instructions for using the rectangle tool, with the current instruction to follow highlighted in green. After you have followed the instructions to add a rectangle measurement to the scan, this box will be replaced by the Selection Mode box, which contains:
      • Name, length, width, height, perimeter, and area of the rectangle measurement.
      • Remove Measurement button: Click to remove the rectangle measurement.
    • Circle Tool box: Lists instructions for using the circle tool, with the current instruction to follow highlighted in green. After you have followed the instructions to add a circle measurement to the scan, this box will be replaced by the Selection Mode box, which contains:
      • Name, diameter, perimeter, and area of the circle measurement.
      • Remove Measurement button: Click to remove the circle measurement.

The center of the page contains either a 2D or 3D model of the selected layer(s) of the part, indicated on the layer bar. You can select which surfaces and sections of the part to display in the Visibility drop-down. If you are in 2D view, you can select one of the measurement tool icons to measure a feature of the selected layer; once created, these measurements will persist on the layer in question until removed, even if you select a different layer. To view the dimensions of a previously-created measurement or to remove the measurement, click on that measurement to load the corresponding Selection Mode box in the top right corner.

Along the bottom of the page, you can see:

  • The selected layer and the total number of layers
  • The vertical height of the part up to the selected layer, to the right of the layer count.
  • Laser Scans bar: Here, each scanned layer is indicated with a box at the corresponding point along the bar. Click a box to load the scan of the respective layer in the center of the page. Note that clicking this box when in 3D view will automatically enable 2D view.
  • Layer bar: This bar represents all the vertical layers which together make up the part. In 2D view, you can click within the bar to select one layer and choose from the Camera Mode and measurement tool icons to view or measure features of that layer. In 3D view, you can select multiple layers by clicking and dragging within the bar, which will display the 3D model of the selected layers in the center of the screen.

The bottom right corner of the page contains the following buttons:

  • Part View: Click to return to the Part View page for the part in question. For more information, see Part View.
  • Print: Click to navigate to the Build View page, from which you can print the part. For more information, see Build View.

 

Accessing Laser Scan Data

When you insert a laser scan after a layer of your part, Eiger will incorporate the scan routine into the MFP file. The scan will begin immediately after the layer finishes printing.

If your print was started via Cloud Eiger, the scan data will be sent directly to Eiger when the scan routine finishes. If your print was started via USB, the scan data will be saved to your printer when it finishes; it will only be accessible via Eiger after the part has finished printing. Follow the instructions below to access scan data.

  1. Navigate to the Print Jobs page in Eiger.
  2. If the print was started via USB: Follow the steps in Importing a Print Job to import the print job and all associated scan data to Eiger.
  3. Enable the Has Scans toggle switch to filter the list of print jobs into only those that have scan data.

  4. Click the Actions button to the right of the print job that you wish to view scan data for.

  5. Select View Laser Scans from the drop-down menu.

In-Process Inspection

In the case of an online print, laser scan data is sent to Eiger as soon as the scan is finished, so you can inspect your part mid-print. This allows you to measure features and ensure that your part is within tolerance. For more information on laser scans, see Insert a Laser Scan after a Layer

Checking Feature Sizes

Eiger provides a series of tools for checking different shapes or geometries.

  1. Navigate to the Scan Inspection page for the print job in question. For more information, see Accessing Laser Scan Data, above.
  2. Select the square icon for the layer you want to view a scan of from the Laser Scans bar.
