Scanning Tips

My Process and Tips for Scanning Objects

With my scanners, the key to a successful scan is ensuring the scanner can continuously track the object. You can achieve this either by using markers or by applying AESUB Blue to improve surface detection.  

When Markers or Scanning Spray Aren't Necessary

Not every object requires markers or scanning spray to achieve a successful 3D scan. Many items with sufficient surface texture, geometric detail, and a non-reflective finish can be scanned accurately without any surface preparation. Objects such as sculptures, castings, carved items, and many manufactured parts often provide enough natural features for the scanner to track effectively. During the assessment process, we determine whether markers, scanning spray, or no preparation at all will provide the best balance of accuracy, efficiency, and surface preservation.

When to Use Markers

Markers work best when:

  • The object has large smooth areas with little detail.
  • The object is symmetrical (pipes, cylinders, spheres).
  • The object is a single color with few distinguishing features.
  • You need maximum accuracy.

Marker Placement Tips

  1. Place markers randomly rather than in straight rows.
  2. Maintain approximately 50-100 mm spacing for medium-sized objects.
  3. Ensure at least 5-8 markers are visible in the scanner's field of view at all times.
  4. Continue markers around the entire object so tracking is maintained when rotating.
  5. For large objects, place extra markers around edges and corners.


When to Use AESUB Blue scanning spray

AESUB Blue is ideal for:

  • Glossy surfaces.
  • Chrome or polished metal.
  • Black shiny plastics.
  • Transparent or translucent objects.
  • Ceramic glazes.
  • Glass.

AESUB Blue creates a thin matte white coating that evaporates after several hours, eliminating the need for cleanup. Typical coating thickness is approximately 8-15 microns.

Proper Application

  1. Clean dust and fingerprints from the object.
  2. Hold the can approximately 15-20 cm away.
  3. Apply light, even passes.
  4. Do not try to make the object solid white immediately.
  5. Wait a few seconds for the coating to dry.
  6. Start scanning as soon as the surface appears evenly matte.


Using Both Together

For difficult objects, the most reliable method is:

  1. Apply AESUB Blue.
  2. Add markers on top of the dried coating.
  3. Scan in marker mode.

AESUB Blue provides a matte surface while the markers provide rock-solid tracking. AESUB specifically notes that reference points adhere well to the coating.

This approach works exceptionally well for:

  • Automotive parts
  • Chrome trim
  • Antique collectibles
  • Royal Doulton figurines
  • Dark glossy 3D printed parts
  • Mechanical components

Recommended Workflow for Collectibles and Antiques

Since you often scan objects for replication and preservation, a reliable workflow is:

  1. Place the item on a turntable.
  2. Apply a light coat of AESUB Blue if the surface is glossy.
  3. Add markers to the turntable (not the object) when possible.
  4. Scan the object from multiple heights:
    • Low angle
    • Mid angle
    • High angle
  5. Flip the object and scan the underside separately.
  6. Align and merge the scans in software.

This method usually produces cleaner meshes with fewer tracking losses and less cleanup afterward.
