Nanoscribe is underpinning its business model in industrial mastering with a 20-page whitepaper with insights into how its patented Two-Photon Grayscale Lithography (2GL ®) technology can be combined with well-proven replication processes. The 2GL technology enables both the rapid fabrication of functional prototypes and its seamless integration into established mass production processes based on nanoimprint lithography (NIL), hot embossing and micro injection molding. The new whitepaper “Industrial upscaling of nano- and microfabrication” was written in partnership with experts from EV Group, 3D AG and kdg opticomp.
New whitepaper: Industrial upscaling of
nano- and microfabrication
Today’s mega-trends of miniaturization and resource efficiency demand advanced microfabrication technologies with fast innovation cycles, improved performance and mass production capability. Nanoscribe’s Two-Photon Grayscale Lithography is the breakthrough technology that enables both, rapid prototyping of nano and microstructures and master template fabrication for seamless integration into established mass production processes.
Miniature designs are required to realize compact, yet extremely performant components in a small form factor. 2GL is designed to fulfill the requirements in microfabrication such as high resolution, excellent shape accuracy and optical-quality surfaces. This additive manufacturing technology is not limited to creating functional prototypes, it also fully fits into advanced replication processes based on nanoimprint lithography (NIL), hot embossing, and micro injection molding. A new publication written by Nanoscribe in partnership with EV Group, NIL specialist, kdg opticomp, technology expert for injection molding, and 3D AG, upscaling expert in nano- and microfabrication, provides insights into various proven manufacturing chains based on the combination of 2GL mastering and replication.
2GL prototyping for state-of-the-art microstructures
Two-Photon Grayscale Lithography is an emerging technology capable of fabricating complex micro- and mesoscale topographies in polymers with submicrometer features. 2GL-printed structures can be used to directly validate the performance of functional parts.
2GL offers enormous design freedom to fabricate discrete and smooth topographies, symmetric and asymmetric microstructures, including challenging geometries such as steep slopes, sharp corners and high aspect ratios, such as required in state-of-the-art microoptics.
2GL mastering fits into replication processes
However, one of today’s challenges in manufacturing microstructures is the scalability of the production chain of these high-precision parts. 2GL also enables rapid and precise microfabrication of master templates for replication with various established technologies such as nanoimprint lithography, micro injection molding and hot embossing. Thus, 2GL-printed structures are transferred to hard stamps such as nickel shims and soft stamps such as wafer-scale working stamps for subsequent replication. These working tools replicate the design and quality of the original master structure and are scalable for series production. Combining 2GL with replication technologies accelerates the transfer from functional prototypes to serial production and shortens time-to-market.
