   Författare :Po-Han Huang; Frank Niklaus; Göran Stemme; Kristinn Gylfason; Yves Bellouard; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Femtosecond laser; 3D printing; self-organized nanogratings; micromachining; silica glass; silicon-rich glass; hydrogen silsesquioxane; photonic microdevice; microsupercapacitor; 2D materials; direct ink writing; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Femtosecond laser-based fabrication technologies have seen rapid developments in the past decades, thanks to the capability of femtosecond lasers to induce localized multiphoton absorption in materials. Multiphoton absorption can result in various material modifications that can be leveraged for additive and subtractive manufacturing. LÄS MER

4. 13. Learning from assessments of resource efficiency measures and their impact on resource use and the environment - Based on a case of additive manufacturing and a review of assessment studies

   Författare :Daniel Böckin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circular economy; repair; 3D-printing; active products; automotive; resource efficiency; reuse; additive manufacturing; remanufacturing; life cycle assessment;

   Sammanfattning : Resource efficiency measures have the potential to reduce the environmental and resource impacts of the current linear economy by decreasing the physical flows of material and energy associated with producing and using products and services. In order to investigate this potential, there is a need for assessments from a systems perspective, which for example enables the identification of possible trade-offs between different measures and aspects of resource efficiency depending on the product characteristics.

5. 14. Study of the flow-induced structure and anisotropy in lyotropic liquid crystals for hierarchical composites

   Författare :Adrian Rodriguez Palomo; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Self-assembly; Lyotropic liquid crystals; SAXS; Hierarchical materials.; 3D printing; Rheology; Microfluidics; Birefringence microscopy;

   Sammanfattning : Controlling the micro and nanostructure of materials is highly beneficial in order to tailor their physical properties. Extrusion-based 3D printing is a promising tool to produce hierarchical structures with controlled architecture. LÄS MER

7. 15. Additive manufacturing of fused silica glass

   Författare :Pawel Maniewski; Michael Fokine; Fredrik Laurell; Daniel Milanese; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser cladding; 3d printing; additive manufacturing; glass; fused silica; laser; scattering; silica; Optik och fotonik; Optics and Photonics; Teknisk materialvetenskap; Materials Science and Engineering;

   Sammanfattning : Additive Manufacturing, of both metals and polymers, has seen rapid development in recent years, whereas the progress in glass has been rather slow. Today, glass can be considered the last frontier without a specialized 3D printing method available. LÄS MER
