In those cases, you will need to spray the part with a matte opaque coating to cover the surface. There are some extreme cases (especially clear surfaces) when your 3D scanner is unable to scan properly even when you have the most ideal scanner settings. Prepare the Part Using a 3D Scanning Spray.However, if you want to scan holes or tight corners with better and cleaner scan results (as light bounces around these features) or if you have an extremely shiny part to scan, we would recommend using a developer spray to prepare the part to get the best results (which is discussed further in the next section). Light then diffuses instead of bouncing directly back into the 3D scanner which is the source of the problem.

When scanning shiny surfaces, scan at a slight angle and distance. Sometimes doing slight adjustments in the way you scan an object can have a big impact on your results. Adjusting The Scanner’s Position In Relation To the Object.Artec Spider/Space Spider: Use the applicable slider in the main scan panel “Advanced” settings.Artec Eva: the sensitivity is adjusted automatically.To increase the 3D scanner’s sensitivity settings: Using the Artec 3D scanner as an example, taking simple actions such as increasing the scanner’s sensitivity and slightly decreasing the brightness helped with scanning this black robe. Example: Artec 3D Scanners Source: Artec article, 3D scanning horror stories! Scan by Second Chance Games & Visual Effects Before you try other methods, see if your 3D scanner’s settings can be adjusted to scanning dark, shiny, or transparent parts.Įach scanner will be different but usually adjusting the exposure settings helps to compensate for the object’s surface characteristics to create a better condition for scanning. Some 3D scanners are pretty good at adapting to surface variations. Transparent surfaces such as glass or clear plastic Metals such as chrome or steel, jewelry, mirrored surfaces, any reflective parts Light scatters and bounces in uncontrollable directions When scanning these challenging surfaces, it causes the following interference: Surface Type They affect how the 3D scanner views the object and consequently affect how it takes the images. While 3D scanners are great at capturing most surfaces, some types of surfaces cause the light to be distorted in such a way that it interferes with the data acquisition process.
