2. 1. Additive manufacturing of fused silica glass

   Author : Pawel Maniewski; Michael Fokine; Fredrik Laurell; Daniel Milanese; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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;

   Abstract : 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. READ MORE

4. 2. Towards sustainability in additive manufacturing: material and process aspects

   Author : Tatiana Fedina; Frank Brückner; Alexander Kaplan; Fabian Riss; Luleå tekniska universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsutveckling; Manufacturing Systems Engineering;

   Abstract : The acceptance of additive manufacturing (AM) depends on the quality of final parts and process repeatability. Recently, many studies have been dedicated to the establishment of the relationship between the process behavior and material performance. READ MORE

5. 3. Interaction mechanisms for a laser-induced metallic boiling front

   Author : Ramiz Saeed Matti Samarjy; Alexander F.H. Kaplan; Torbjörn Ilar; Michael Schmidt; Luleå tekniska universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser remote fusion cutting; Boiling front; High speed imaging; Additive manufacturing; Ejection; Absorption; Wavy surface; Deposition; Produktionsutveckling; Manufacturing Systems Engineering;

   Abstract : This thesis is about fundamental interaction mechanisms of laser remote fusion cutting, RFC, which is based on the formation of a quasi-stationary laser-induced boiling front that causes drop ejection, preferably downwards. Laser cutting of metals, invented in 1967, has developed from a niche to a well established high quality cutting technique in the manufacturing industry. READ MORE

6. 4. Essays on Manufacturing Production in a Developing Economy: Kenya 1992-94

   Author : Karl Lundvall; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
   Keywords : Firm size; Kenya; manufacturing; stochastic frontier production functions; data envelopment analysis; technical efficiency; factor substitution; informal sector.;

   Abstract : The dissertation consists of five separate empirical papers based on panel data from Kenyan manufacturing firms in the food, wood, textile and metal sectors, collected during the early 1990s, and an overview of the economic literature on small firms in developing countries. The principal tools of analysis are the microeconomic theory of production and econometrics. READ MORE

7. 5. Manufacturing and Characterization of Cellulose Nanofibers

   Author : Carl Moser; Mikael Lindström; Gunnar Henriksson; Kristin Syverud; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose; Nanofibers; Characterization; Homogenization; Endoglucanase; TEMPO; Specific surface area; Atomic force microscopy; Cellulosa; Nanofibrer; Karakterisering; Homogenisering; Endoglukanas; TEMPO; Specifik ytarea; Atomkraftmikroskopi; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : The usage of wood has been a dominant driving force during the evolution of the human species. It allowed us to cook food, build tools, put roofs over our head and explore the world. The fibers making up the tree has been the most important way to store and transmit knowledge in the form of paper for centuries. READ MORE
