Sprays (including the disappearing one!)

 [Updated on April 12, 2018]

In most cases, you won’t need to spray an object before 3D scanning (thanks to the Sensitivity feature!). Nevertheless, it’s useful to know which sprays our Partners and customers use when an object surface is too shiny, too transparent or otherwise difficult to capture. This article offers you guidelines for choosing a spray.

Important note: always observe safety precautions before applying a spray.

 

Helling 3D Laserscanning Anti-Glare Spray

  • Company: Helling GMBH. Visit https://3dscanspray.com/, for example, to purchase this spray
  • Feature: may be the most frequently used and recognizable option :) Almost every time we hear about customers using a spray, they mention Helling.
  • Note: requires manual removal after 3D scanning

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 geometry features you’d like to capture)

Below are some results for 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.

Krylon Dulling Spray (link)

  • Company: Krylon
  • Feature: originally recommended to us by a U.S. customer; it leaves the texture almost unchanged from the original while removing “shininess” and adding an antireflection coating over the surface

Kenro Kenair AntiReflect Full Matt Spray (link)

  • Company: Kenro
  • Feature: eature: an analog of Krylon, tested and recommended by our Gold Partner Antonius Köster
