2PP is bridging the gap between micro and macro scale
Nanoscribe’s 3D printers are based on the non-linear optical process of two-photon polymerization (2PP). This technology is used for 3D laser lithography and provides the highest possible precision in additive manufacturing.
The Photonic Professional GT2 offers more than 100-fold higher resolution than standard 3D printers do. With extended capabilities and improved process speed, Nanoscribe's 3D printers bridge the gap between micro and macro scale. For the first time 3D fabrication on the mesoscale is mastered up to the macroscale.
Into the basics: two-photon polymerization
Nanoscribe’s 2PP technology uses a laser that is focused inside a photoresin, typically a liquid photosensitive material. The laser exposes the photoresin only within the tight focal point and cures a 3D object by scanning the laser focus along the trajectories of a CAD design. After the printing process, the 3D printed part is surrounded by unpolymerized resin, which is removed in a developer bath.
Nanoscribe’s 3D printers combine the technology of two-photon polymerization with the printing workflow of standard additive manufacturing processes. Thus the focus of a femtosecond laser cures a negative-tone resin layer by layer. This enables the manufacturing of micro- and mesoscale parts with complex designs and high shape accuracy in an additive way. Read More »
Multiphoton lithography also allows subtractive manufacturing of positive-tone resists. Nonlinear light absorption triggers a local depolymerization of the material that can be easily washed away in a developer bath. Read More »
The use of the printing material photoresin as the final material fits many fields of application in science and industry. But some applications require other materials that cannot be printed directly by two-photon polymerization. For these cases, post-print processes allow to modify the 3D polymer printed parts to reach metals, silicon, carbon or PDMS.
Nanoscribe develops solutions for industrial applications in close collaboration with industrial partners and within the context of funded projects. Read More »
