  1. 1. Selective laser sintering for 3D printing of medications

    Author : Evgenii Tikhomirov; Jonas Lindh; Julian Quodbach; Maria Strömme; Ocean Cheung; Jarkko Ketolainen; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; 3D printing; Selective laser sintering; Personalized medicines; Drug manufacturing; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

    Abstract : Suboptimal treatment caused by inaccurate dosing of prescribed medications is a challenging issue for the pharmaceutical industry. As a result, certain groups of patients, especially pediatric patients, may suffer from a lack of specific dosage forms, leading to potential side effects. READ MORE

  2. 2. Laser sintered materials with Non-equilibrium structures

    Author : Bin Qian; Zhijian Shen; Germán F. de la Fuente; Stockholms universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser sintering; Materials; Non-equilibrium structures; microstructure; hierarchical structure; Inorganic Chemistry; oorganisk kemi;

    Abstract : This thesis is focused on achieving materials with non-equilibrium structures fabricated by high-energy laser sintering. The chosen precursor materials have rigid and inert structures like high-melting point ceramics or metals. READ MORE

  3. 3. Mechanical properties and microstructure of laser sintered and starch consolidated iron-based powders

    Author : Yu Wang; Jens Bergström; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Powder metallurgy; Laser sintering; Microstructure; Fatigue; Thermal fatigue; Wear; Starch consolidation; Rapid forming; Net shaping; Liquid phase sintering; Nitriding; High speed steels; Materials science; Teknisk materialvetenskap; Materialteknik; Materials Engineering;

    Abstract : In powder metallurgy research field, Direct Metal Laser Sintering (DMLS) and Metal Powder Starch Consolidation (MPSC) are relatively new rapid forming techniques to fabricate complex and near net-shaped components. The working principles of DMLS are to melt and fuse metal powder layer by layer in computer controlled systems to pile up components like three dimensional printing. READ MORE

  4. 4. Additive manufacturing of fused silica glass

    Author : Pawel Maniewski; Michael Fokine; Fredrik Laurell; Daniel Milanese; KTH; []
    Keywords : 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
