The multiphoton polymerization technique enables the production of arbitrary shaped 3D structures from various polymers. The single linewidth of the woodpile photonic crystal shown in the illustration is lower than 200 nm.
3D Chain-Mail Structure
Standard 3D printing does not enables printing of movable structures. These structures can be fabricated inside a gel or liquid monomer by using the multiphoton polymerization technique which makes support‑free 3D printing possible.
3D Gyroid Structure
Multi-photon polymerization is a suitable technology for meta-material fabrication. Metamaterials are composites whose physical properties are different from those of the materials they are made from.
Microoptics is one of the applications for multi‑photon polymerization (MPP) technology. The illustrated lens has a diameter of 500 µm. Superb nearly spherical aberration-free focusing can be obtained in each Fresnel zone.
3D Structures on Fiber Tip
The microlens with a diameter of 50 µm is fabricated on top of the fiber. The 3D supports ensure a required 250 µm distance between the fiber tip and the lens.
Scaffold-like structure can be produced within a resolution of up to 150 nm capable of entrapping submicrometer sized cells by multiphoton polymerization (MPP) technique.
The multiphoton polymerization technique with hybrid polymers in combination with pyrolysis enables the removal of the organic part of the polymer and produces ceramic structures. Structure shrinkage during pyrolysis is homogeneous and is approximately 25 %.
Prism for Elipsometry
Multiphoton polymerization is a flexible technique that allows different quality and various functionality surfaces to be maintained on the same structures depending on the needs of the application.
3D laser lithography is a suitable technology for the production of high-precision micromechanical components, an example being the single-helix three-turn 3D meso-spring for micro-mechanical applications.
One of the best ways to produce them is the multi-photon polymerization technique which enables the production of precise and firm microneedles. Even more complex shapes of polymeric needles can be obtained by maintaining the high sharpness of the needle tips.
3D Glass Structures
Selective laser etching (SLE) technology enables the fabrication of true 3D glass structures with complex architecture, for instance, fullerene molecule‑like structures.
