Thanks to the Sensitivity feature in Artec Studio, it is seldom required to spray an object before 3D scanning. Nevertheless, for those cases where the object is too shiny, too transparent, or otherwise difficult to capture; it is good to know which spray to use. This article offers some guidelines on choosing a suitable scanning spray. It was written with the help of our experienced partners and customers.
Important note: before applying any of the sprays listed below, always observe the safety precautions. Each spray has its own set of precautions which are written on the label of the spray can.
Reflecon spray (very fine grain), applied via an airbrush system and recommended specifically for the Artec Micro scanner
- Company: Reflecon (a trademark of Mr. Chemie GmbH): https://www.reflecon.com/
- Feature: the tarnish-30-hc (volatile) and tarnish 80 (non-volatile) products offer a grain size of a mere ~5 µm. This allows for a very fine layer of spray to be applied to the object and is optimal when working with the Artec Micro scanner.
- Note: Spray cans tend to have a much thicker grain and a messier dispersion, which makes them unsuitable for use with the Micro scanner. Certain Space Spider applications may also benefit from the airbrush.
Helling 3D Laserscanning Anti-Glare Spray
- Company: Helling GMBH. Can be purchased at https://3dscanspray.com/
- Feature: possibly the most frequently used spray of all. A large number of customers report using this specific spray.
- Note: requires manual removal after 3D scanning (with a microfibre cloth, dusting brush or similar).
Cyclododecane Spray (link)
- Company: Kremer Pigmente (http://kremer-pigmente.de/en).
- Feature: evaporates from an object within several hours of application.
- Note: apply with care to avoid “snowflake effect” on the surface (doing so is critical if the object has small geometrical features that you’d like to capture).
The pictures below show a skull that was fully covered with Cyclododecane spray. Note that the applied layer was intentionally thick, since the goal was to calculate the maximum time required for the spray to evaporate.
- Photo 1: 0 hours after applying the spray
- Photo 2: 3 hours after application (partial evaporation)
- Photo 3: 20 hours after application
Artec Gold Partner Patrick Thorn shared another picture with us (a hi-res version is available at the end of the article):
AESUB blue Spray (link)
- Company: Scanningspray Vertriebs UG. Can be purchased here: https://aesub.com/distributors
- Feature: One of the newest additions to this list (07/2019). Evaporates from an object within several hours of application.
- Note: Applies smoothly with very little flake formation (see "snowflake effect" in the Cyclododecane spray description above), therefore optimal for small geometry. Facilitates the scanning of difficult surfaces. Evaporates faster in comparison with the Cyclododecane spray and has a less noticeable smell.
Highly recommended by our in-house scanning gurus.
CEREC® Optispray (link)
- Company: Sirona Dental Systems GmbH
- Feature: This spray is as non-toxic as it gets and is designed for intraoral applications (e.g. scanning teeth). It has a pleasant spearmint scent and taste.
A thin, homogeneous contrast layer helps deliver precise digital impression results.
- Demonstration video: YouTube / LinkedIn
- Documentation: SDS (Safety Data Sheet) and Operating instructions
Krylon Dulling Spray (link)
- Company: Krylon
- Feature: This spray was recommended to us by a U.S. customer. It leaves the texture (color of the object) almost unchanged from the original, while effectively removing the “shininess”. It works by adding an almost transparent, antireflective layer to the surface of the object.
Kenro Kenair AntiReflect Full Matt Spray (link)
- Company: Kenro
- Feature: very similar to the Krylon spray above, this spray was tested and recommended by our Gold Partner Antonius Köster
Gold Bond No Mess Spray Powder Fresh (link)
- Company: Gold Bond
- Feature: while this is not a scanning spray per se but rather a foot/body spray, it works surpisingly well. It is very easy to apply and creates an even and uniform antiglare layer on the object.
