TL;DR: In this paper, a thermally conducting composite material that can be rapidly 3D printed into prototype objects is presented using a low-cost stereolithographic 3D printer, where the composite structures containing 10, 20, 25 and 30% (w/v) of 2-4 micron sized synthetic diamond microparticles added to the acrylate polymer were produced using a high resolution scanning electron microscopy, thermogravimetric analysis and thermal imaging.
Abstract: The development of a thermally conducting composite material that can be rapidly 3D printed into prototype objects is presented. The composite structures containing 10, 20, 25 and 30% (w/v) of 2–4 micron sized synthetic diamond microparticles added to the acrylate polymer were produced using a low cost stereolithographic 3D printer. The prepared materials were characterised according to heat transfer rates, thermal expansion co-efficients and contact angles, and analysed using high resolution electron microscopy, thermogravimetric analysis and thermal imaging. The composites displayed minor enhancements in heat transfer rates with incrementing diamond content upto 25% (w/v), however a significant improvement was observed for the 30% (w/v) polymer–diamond composite, based on an interconnected diamond aggregate network, as confirmed by high resolution scanning electron microscopy. The developed material was used in the fabrication of prototype 3D printed heat sinks and cooling coils for thermal management applications in electronic and fluidic devices. Infrared thermal imaging performed on 3D printed objects verified the superior performance of the composite compared to the inherent polymer.

TL;DR: In this article, the authors used direct write nanolithography to repair and fabrication of photomask repair, including use of scanning probe microscopic tips for deposition of ink materials including solgel and metallic inks.
Abstract: Photomask repair and fabrication with use of direct-write nanolithography, including use of scanning probe microscopic tips for deposition of ink materials including solgel and metallic inks. Additive methods can be combined with substractive methods. Holes can be filled with nanostructures. Height of the nanostructure filling the hole can be controlled without losing control of the lateral dimensions of the nanostructure. Chrome-on-Glass masks can be used and fabricated, as well as more advanced masks including masks for nanoimprint nanolithography.
