3D prints get another layer of security from Nanoscribe two-photon lithography

The security of 3D printed parts is a chief concern for high-value manufacturers in industry. Quantum dots, that glow when hit with a UV light, are one possibility for protecting 3D prints from counterfeiting . Chemical “ghost signatures” are another, and can be found embedded in the layers of 3D printed parts. Working with two-photon lithography, i.e. 3D microprinting, Nanoscribe has developed a new method for creating microscopic security features. A microscope on two-photon lithorgaphy In two-photon lithography a pulsed laser is used to solidify a photoreactive material in a series of layers. The size of the laser’s focal […]
