Dynamic Precision Printing for optimized 3D Microfabrication
The optical tweezers in this fascinating work are printed using different printing strategies. Printing the beam expansion part requires less precision than the filigree microstructures of the optical Fresnel lenses. Therefore, the first section on the fiber can be printed with higher scan speeds and coarser slicing and hatching parameters. For the Fresnel lenses, on the other hand, the writing parameters are set to the highest resolution. Using the strategy of adjusting the print parameters to the functionality of the desired object, the scientists printed these high-precision optical tweezers in less than an hour. Incidentally, this strategy is also the core idea behind our Dynamic Precision Printing modes to guide users to a perfect balance of precision and speed by offering different printing modes.
Tomorrows applications thanks to Nanoscibe’s technology
The key element of the Stuttgart research team’s fascinating work is a microfabricated Fresnel lens printed directly onto the facet of an optical fiber. Therefore, 2PP-based microfabrication enables easy design iterations and modifications of these 2.5D lenses. In addition, the technology enables microfabrication of complex stacked 3D lens designs. In this context, Nanoscribe’s new Quantum X shape paves the way for similar and new innovations. The new system integrates the revolutionary technology of Two-Photon Grayscribe Lithography (2GL ®) for smooth 2.5D optical-grade elements, such as the described Fresnel lenses, and 3D capabilities for printing freeform microstructures with unprecedented precision. Stay tuned for the more exciting news to come.
