Reflecon TopoTrack

The TopoTrack 3D scanning spray from Reflecon is sublimating spray designed to matte the scanned object and thus improve scanning results with challenging surfaces such as reflecting, mirroring, transparent, or dark areas. The TopoTrack spray was specially optimized to streamline 3D laser scanning processes where normally trackers must be used. Thanks to its special formulation, the TopoTrack spray reduces or eliminates the need for markers by creating a reference structure system that helps the scanner orient itself on a large surface. The effect of this scanning spray is especially pronounced with high resolution 3D scanners.

Thanks to its long sublimation time (12-24 hours), the TopoTrack scanning spray is ideal for the scanning of very large objects or batches in applications such as R&D, metrology, quality control, and reverse engineering. The TopoTrack spray can be used with a wide range of materials, including ferrous materials like cast uncoated steel, non-coated non-ferrous materials such as wood, glass, and ceramics, objects coated with 2-component lacquer, and numerous plastics such as PE, PP, PET and PA.

Key features of TopoTrack include a residue-free application, and no dust generation during spraying. These qualities keep the workspace clean and protect 3D scanning equipment while preventing contamination in sensitive environments such as laboratories. It is recommended to test the spray's suitability on an invisible spot before full application to avoid potential damage to the object being scanned.

The sublimation time of TopoTrack ranges from 12-24 hours, depending on factors such as the material, surface texture, and ambient temperature. Higher temperatures, especially above 30°C, shorten the sublimation time, while lower temperatures extend it. Rough surfaces can prolong sublimation time, whereas smooth surfaces accelerate the process. Applying a thicker layer can also increase sublimation time. The recommended layer thickness for optimal results is 5-35 μm.

Before using TopoTrack, it is essential to clean the scanned objects thoroughly to prevent residue on the surface. Detailed guidance on application and compatibility can be found in the Usage Tips section and a full compatibility table is available in the Downloads section.
