Area of Science:

Materials Science
Chemistry
Information Security

Background:

Current encryption methods are limited to planar surfaces, hindering security applications on complex 3D objects.
Developing effective encryption strategies for nonplanar surfaces is crucial for advanced product anti-counterfeiting and information security.

Purpose of the Study:

To report a novel approach for direct encryption on 3D-printed objects using orthogonal photochemistry.
To demonstrate a method for encoding information onto geometrically complex, nonplanar surfaces.

Main Methods:

Utilized visible light photochemistry for 3D printing of a hydrogel material.
Employed ultraviolet light to spatioselectively activate the hydrogel surface via dissociation of ortho-nitrobenzyl ester units for information coding.

Main Results:

Successfully demonstrated direct encryption on a 3D-printed object with a complex surface.
Established an orthogonal photochemistry system enabling information coding on nonplanar surfaces.

Conclusions:

The reported approach provides a new pathway for highly reliable encryption on 3D-printed products.
The underlying orthogonal photochemistry has potential for broader applications in functional modification of 3D-printed items beyond security.
