High-throughput thermal replication of transparent Fused Silica glass
Microfluidics BioMEMS and Medical Microsystems XVII, 2019Co-Authors: Frederik Kotz, Norbert Schneider, Andreas Striegel, Matthias Worgull, Bastian E. RappAbstract:Fused Silica glass is the material of choice whenever high chemical and thermal resilience combined with high optical transparency is required. These properties make Fused Silica glass interesting in microfluidics for next generation chemical synthesis reactors as well as microoptics and photonics. However structuring of Fused Silica glass is difficult and upscaling of microfluidic concepts in glass from laboratory scale prototypes to mass market manufacturing remains a problem. Polymers on the other hand remain the material of choice for low cost, disposable components in mass market manufacturing. We want to close the gap between the superior material properties of Fused Silica and the ease of highthroughput polymer molding. Here we present high-throughput thermal replication of Fused Silica glass using thermal nanoimprinting and roll-to-roll replication. Therefore, thermoplastic nanocomposites are structured using classical polymer molding processes at moderate temperatures of 110°C and pressures of 27°MPa. Structuring can be done with submicron resolution and a surface roughness of a few nanometers. Roll-to-roll replication allows structuring these thermoplastic nanocomposites with speeds up to 5 m/min. The structured thermoplastic nanocomposites are then turned into Fused Silica glass in a final heat treatment.

three dimensional printing of transparent Fused Silica glass
Nature, 2017Co-Authors: Frederik Kotz, Karl Arnold, Kai Sachsenheimer, Christiane Richter, Tobias M. Nargang, Nico Keller, Werner Bauer, Dorothea Helmer, Dieter Schild, Bastian E. RappAbstract:Using stereolithography 3D printers, a Silica nanocomposite is shaped and then Fused to produce non-porous, very smooth, highly transparent Fused Silica glass components. Fused Silica glass has long been known for its excellent optical properties, yet processing and patterning this material still requires high-temperature processes and/or hazardous chemical materials. To simplify such processes, Bastian Rapp and colleagues have been developing a system—termed 'liquid glass'—in which a viscous amorphous Silica nanocomposite can be patterned into complex shapes by moulding and then photocured to produce optical-quality glass structures. In their latest development, the group have tuned the properties of their nanocomposite to facilitate its use in a 3D printer, yielding high-optical-quality glass structures with features as small as a few tens of micrometres. Glass is one of the most important high-performance materials used for scientific research, in industry and in society, mainly owing to its unmatched optical transparency, outstanding mechanical, chemical and thermal resistance as well as its thermal and electrical insulating properties1,2,3. However, glasses and especially high-purity glasses such as Fused Silica glass are notoriously difficult to shape, requiring high-temperature melting and casting processes for macroscopic objects or hazardous chemicals for microscopic features3,4. These drawbacks have made glasses inaccessible to modern manufacturing technologies such as three-dimensional printing (3D printing). Using a casting nanocomposite5, here we create transparent Fused Silica glass components using stereolithography 3D printers at resolutions of a few tens of micrometres. The process uses a photocurable Silica nanocomposite that is 3D printed and converted to high-quality Fused Silica glass via heat treatment. The printed Fused Silica glass is non-porous, with the optical transparency of commercial Fused Silica glass, and has a smooth surface with a roughness of a few nanometres. By doping with metal salts, coloured glasses can be created. This work widens the choice of materials for 3D printing, enabling the creation of arbitrary macro- and microstructures in Fused Silica glass for many applications in both industry and academia.

Glassomer-Processing Fused Silica Glass Like a Polymer.
Advanced Materials, 2018Co-Authors: Frederik Kotz, Nico Keller, Werner Bauer, Dieter Schild, Norbert Schneider, Andreas Striegel, Andre Wolfschläger, Matthias Worgull, Marcel Milich, Christian GreinerAbstract:Fused Silica glass is one of the most important high-performance materials for scientific research, industry, and society. However due to its high chemical and thermal resistance as well as high hardness, Fused Silica glass is notoriously difficult to structure. This work introduces Glassomer, a solid nanocomposite, which can be structured using polymer molding and subtractive technologies at submicrometer resolution. After polymer processing Glassomer is turned into optical grade Fused Silica glass during a final heat treatment. The resulting glass has the same optical transparency as commercial Fused Silica and a smooth surface with a roughness of a few nanometers. This work makes high-performance Fused Silica glass components accessible to high-throughput fabrication technologies and will enable numerous optical, photonic and medical applications in science and industry.
