Femtosecond microfabrication in scaffolds applications utilizes multi-photon polymerization technology to create meta-materials with unique physical properties. The WOW distance approach is used to fabricate a 3D gyroid structure that is mechanically rigid, light and of arbitrary geometry, making it suitable for scaffold manufacturing. MPP technique allows for the formation of high resolution structures of different shapes and sizes, perfect for cell-size cages in tissue engineering.
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.
Multiphoton-polymerization (MPP) is a technology that enables the production of arbitrary shape polymeric structures within submicrometric resolution. First, a photoresist sample is prepared by drop-casting polymer material mixed with a photoinitiator on the glass slide and then pre-baking.
A feasibility study is composed of several steps, including researching methods for fabricating micro-structures, fabricating a micro-structure prototype, measuring and aligning the prototype with technical requirements, and finally preparing a study report.
