2PP in a Nutshell
Direct laser writing by two-photon polymerization (2PP) of photosensitive materials is a novel technique for fast and flexible fabrication of fully three-dimensional (3D) microstructures.
It is based on the photopolymerization of photo resin with femtosecond lasers.
In comparison to stereolithography or 3D printing, a significantly higher resolution well below 500 nm can be achieved.
Fields of application are for example:
- Micro optics
- Micro fluidics
- Micro structured surfaces
- Biology
- Medicine
Our experts have been working and researching this technology continuously since 2000.[1]
Our M4D systems and our femtoBond photoresists are based on this long-term experience.
