Start by checking the instructions for your exact scanner and capture mode. If the untreated surface will not scan reliably, a compatible matte coating or 3D scanning spray may help—but test it first, especially on delicate, valuable, or dimensionally critical objects.
Why these surfaces are difficult to scan
Many optical scanners project light onto an object and use the returning pattern to reconstruct its shape. Different finishes disrupt that process in different ways: black material may absorb projected light, a polished surface may reflect it unpredictably, and a transparent surface may let light pass through rather than return from its exterior. Translucent materials can scatter light, while fur and hair lack the stable solid surface a scanner expects. A dark, polished object can combine more than one of these problems. Artec explains these optical-surface challenges.

These are capture challenges, not proof that an object cannot be scanned. Results depend on the scanner, its selected mode, the object’s geometry, setup, and the accuracy the project requires. A mode that handles some dark or shiny surfaces does not necessarily handle transparent ones, and a claim about one model or mode should not be generalized to every scanner.
Choose a workflow for the object and its purpose
Before changing settings or treating a surface, identify its finish and decide what the scan needs to do. A model for visualization may tolerate gaps that would make a scan unsuitable for reverse engineering or dimensional inspection.
#1 Best Overall
- Attention: All scanning sprays contain solvents. Perform a material compatibility test before use to ensure no damage to the object.
- Semi-Permanent: Leaves an optimal surface for 3D scanning until easily wiped or washed off. Please note that you should promptly wipe off the powder from the surface of the object after scanning.
- Designed for 3D Scanning: Makes transparent, reflective, and other hard to 3D scan surfaces capturable by matting them and preserving surface detail with a thin 4.5 µm (approximately) coating.
- Works on Surfaces: Adheres to all porous and non-porous surfaces such as textiles, wood, glass, painted surfaces, metal, plastic, stone, mortar, and paper.
- Identify the surface: Is it dark, glossy, transparent, translucent, low-texture, or a combination?
- Define the output: Is the scan for visualization, 3D printing, CAD reconstruction, or dimensional inspection? For inspection, establish the required tolerance and acceptance method before capture.
- Check the exact mode: Read the instructions for your scanner, software version, and capture mode. Revopoint says some of its laser modes can capture certain dark or shiny surfaces without spray under suitable conditions; that is a manufacturer statement, not an independent comparison, and it does not establish that untreated transparent surfaces will scan reliably.
- Check constraints: Decide whether a coating or tracking markers can touch the object, and consider its size, recesses, hidden areas, smallest important detail, working distance, and tracking method.
Prepare the surface only when needed and safe
If the chosen mode cannot capture the untreated surface cleanly, a suitable matte coating or 3D scanning spray may make it easier for an optical scanner to read. Preparation options differ: Artec recommends scanning spray or another suitable coating, and its Artec Studio 17 documentation also mentions removable paint or talcum powder. SHINING 3D describes temporary and permanent coating sprays. These options are not interchangeable guarantees of safety or removability: follow the product instructions and confirm that treatment is appropriate for the object.
Test before coating the whole object
- On a delicate, valuable, porous, or dimensionally critical item, test a representative, inconspicuous area first.
- Confirm that the treatment can be removed safely and will not affect finishes, fine edges, or dimensions that matter.
- If coating is prohibited, do not assume a temporary spray is harmless or dimension-neutral. Try a supported mode or careful adjustments to angle, distance, and lighting, then assess whether the untreated scan meets the project’s needs.
- For production or inspection work, document any surface treatment used.
Set up lighting, angle, and distance
Clean fingerprints from the surface, then arrange the workspace to reduce unwanted reflections into the scanner. For a reflective object, change the viewing angle and distance in small increments and check whether the return becomes stable; tilting the scanner may help in some workflows. Avoid direct sunlight where the scanner’s instructions call for even lighting. Keep within the device’s supported working range rather than assuming that moving closer will improve the scan.
Rank #2
- Attention: All scanning sprays contain solvents. Perform a material compatibility test before use to ensure no damage to the object.
- Designed for 3D Scanning: Makes transparent, reflective, and other hard to 3D scan surfaces capturable by matting them and preserving surface detail with a thin 6.5 µm (approximately) coating.
- Long Scan Time: Leaves an optimal surface for 3D scanning for up to 6 hours.
- No Cleaning Needed: The coating will sublimate (dissolve) in around 6 to 24 hours (depending on the environment), leaving no residue behind.
- Works on Surfaces: Adheres to all porous and non-porous surfaces such as textiles, wood, glass, painted surfaces, metal, plastic, stone, mortar, and paper.
Capture with steady movement and enough overlap
Move deliberately, not in long, fast passes. Adjacent frames or separately captured regions need enough shared, usable surface information for the software to align them. Artec Studio’s guidance is to avoid moving too fast, capture common areas between scans, and include a little extra coverage when going around an object in one pass. See the Artec Studio 17 scanning guidance.
Follow the scanner’s own tracking rules
If your system uses markers, use the count and placement specified in its manual; there is no universal marker rule. In its cited laser-mode preparation guide, SHINING 3D calls for four markers for alignment, recommends keeping at least four visible within the normal scanning range, and advises spreading them evenly in an irregular rather than grouped or symmetrical arrangement. That advice applies to the described SHINING 3D workflow, not to every scanner. Its guide also describes a marker-equipped manual turntable and marker dice as possible aids for small dark or reflective objects. Check SHINING 3D’s guidance.
Rank #3
- Designed for 3D Scanning: Ideal for transparent, black, and reflective surfaces to improve scanning accuracy.
- Fast Evaporating & No Cleaning: Dries quickly and leaves no residue, suitable for scanning various materials.
- Compatible with Multiple Scanners: Works well with 3DMakerpro Seal and Moose handheld 3D scanners, as well as other brands.
- Easy to Use: Spray from 15–20 cm, apply evenly over the object surface, then scan with your 3D scanner.
- Large 400ml Capacity: Enough to complete scanning of medium-sized objects.
Inspect and validate the mesh
A mesh that looks complete on screen is not automatically accurate enough for its intended use. Review the result for holes, missing edges, alignment errors, duplicated or unwanted background geometry, and flipped normals. For 3D printing, also check thin walls and other features relevant to the model’s intended fabrication. Revopoint recommends checking these issues in its black- and shiny-surface guidance.
For CAD or reverse engineering, compare important dimensions with a trusted measurement. For inspection, decide in advance how measurements will be made and what tolerance the result must meet. Treat a scan as acceptable only against a method suited to that requirement; no universal accuracy figure or spray-related improvement is established by the cited guidance.

Compare candidate workflows before committing
If more than one scanner or setup could work, compare the complete process—not just a product specification. A representative sample capture should include any preparation, scanning, alignment, export, and validation you expect to use.
