1. 11. Qualification of Metal Additive Manufacturing in Space Industry : Challenges for Product Development

   Författare :Christo Dordlofva; Anna Öhrwall Rönnbäck; Peter Törlind; Ola Isaksson; Marco Bertoni; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; Space industry; Product Development; Qualification; Design for Additive Manufacturing;

   Sammanfattning : Additive manufacturing (AM), or 3D printing, is a collection of production processes that has received a good deal of attention in recent years from different industries. Features such as mass production of customised products, design freedom, part consolidation and cost efficient low volume production drive the development of, and the interest in, these technologies.

4. 13. On Characterization and Optimization of Surface Topography in Additive Manufacturing Processes

   Författare :AMOGH VEDANTHA KRISHNA; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; areal surface texture parameters; additive manufacturing; power spectral density; vat-photopolymerization; laser-based Powder bed fusion; fused deposition modeling; profile parameters; feature-based characterization; and multiple regression.; scale-sensitive fractal analysis; surface metrology;

   Sammanfattning : With its ability to construct components through the layer-by-layer deposition of material, Additive Manufacturing (AM), more commonly known as "3D printing", has revolutionized the manufacturing industries. Not only can AM produce complex lightweight designs, but it can also streamline the supply chain, allowing businesses to more quickly and easily meet customer demand. LÄS MER

5. 14. Mechanical Properties, Microstructures and Defects of Tool Steels Fabricated by Additive Manufacturing

   Författare :Yuan Miwen; Chalmers tekniska högskola; []
