3D Scanning Spray Streamlines Scanning Process By Eliminating Reference Points

3D scanners often need reference points for orientation, which are usually attached to the object before scanning and removed afterward. This process can be particularly time-consuming for larger components. The newly launched TopoTrack forms a structure on the surface, allowing the scanner to orient itself and maintain tracking stability. This innovation eliminates the need for glued-on reference points, enabling faster manual guidance of the scanner.

The Reflecon TopoTrack 2-in-1 Scanning Spray significantly reduces the time required for 3D scanning. This efficiency is achieved not only by removing the need for attaching and detaching reference points but also because users can guide the scanner over the object more swiftly. Besides providing classic matting, essential for transparent, shiny, and highly reflective objects, TopoTrack offers tracking support with its special structure, eliminating the need for additional aids during the scanning process. The spray sublimates and lasts for 12-24 hours, making it ideal for large objects without the need for subsequent cleaning.

How Does TopoTrack Work?

The name TopoTrack combines ‘topography’ and ‘tracking.’ The spray forms a topographical layer resembling woodchip wallpaper under a microscope. This randomly changing structure allows a high-resolution scanner to orient itself.

The spray’s layer thickness is a maximum of 35μm per application, suitable for most applications, especially large objects. The graphic above illustrates how the spray forms a homogeneous ‘mountains and valleys’ structure over the entire surface of the part.

For optimal results with the 0-35μm structure, MR Chemie GmbH, the developer of TopoTrack, recommends using a high-resolution scanner with slight overexposure and activated texture support. LED, white light, and infrared light scanners with a small field of view benefit the most, as they are less likely to detect the object’s inherent geometries or textures. Laser scanners, however, still require reference points due to systemic reasons.
