MIT researchers have developed BrightMarker, which are innovative, 3D-printed fluorescent markers for object tracking that can be embedded into physical items. BrightMarkers could one day replace QR codes and only require users to download the CSAIL team’s software plugin for 3D modeling programs like Blender before printing them.
Once the tag is placed within the geometry of the design, it can be exported as an STL file for 3D printing. This file can then be printed using fluorescent filaments, resulting in an object with a hidden tag. One caveat: these must be embedded into an object before it’s fabricated, meaning you can not add them on existing objects. To scan these invisible markers, the researchers developed both AR and VR headsets capable of viewing as well as scanning them. The surrounding objects would be obscured using a longpass filter, while an attachable piece then spots only the fluorescence.

In a future dominated by the AR and VR paradigm, object recognition, tracking, and traceability is crucial for connecting the physical and digital worlds: BrightMarker is just the beginning. BrightMarker’s seamless tracking marks the start of this exciting journey into a tech-powered future,” said Raúl García-Martín, MIT CSAIL visiting researcher.
