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.
The 3D gyroid structure is mechanically rigid, but light. The structure is fabricated by using the widened objective working (WOW) distance approach, with which the working distance of the high numerical aperture objective can be increased. The overall size of this structure – is 1 mm × 1 mm × 1 mm. The structure height is much greater than the working distance of the objective used (0.19 mm). This microfabrication technique makes it possible to fabricate mesoscale structures – structures whose total size is a few orders larger than their finest feature.
Multi-photon polymerization (MPP) can be used for meta-material fabrication, including scaffolds for tissue engineering. The 3D gyroid structure is a mechanically rigid, light structure that can be fabricated by MPP, with a resolution up to 150 nm and capable of entrapping submicrometer sized cells.
Applying for Industries
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.
Contract Research Services
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.
