   Abstract : Design of new materials with complex geometries is an important part of new innovative solutions for technical applications. With the use of additive manufacturing (AM), the design possibilities are endless and geometries that are impossible to manufacture by conventional techniques are available. READ MORE

5. 18. Alloy Design and Characterization of γ′ Strengthened Nickel-based Superalloys for Additive Manufacturing

   Author : Jinghao Xu; Johan Moverare; Ru Lin Peng; Eric Jägle; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nickel-based superalloy; Alloy design; Laser powder bed fusion; Cracking susceptibility; Additive manufacturability; Heat treatment; γ′ precipitate; High-temperature mechanical property; Creep.;

   Abstract : Nickel-based superalloys, an alloy system bases on nickel as the matrix element with the addition of up to 10 more alloying elements including chromium, aluminum, cobalt, tungsten, molybdenum, titanium, and so on. Through the development and improvement of nickel-based superalloys in the past century, they are well proved to show excellent performance at the elevated service temperature. READ MORE

6. 19. On customization of orthopedic implants - from design and additive manufacturing to implementation

   Author : Marie Cronskär; Mats Tinnsten; Mikael Bäckström; Lars-Erik Rännar; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Patient-specific implants; Additive manufacturing; Electron beam melting; Multibody musculoskeletal analysis; Orthopedic implants; Clavicle; Finite element analysis; Computer aided design; Osteosynthesis plate; Hip stem implants;

   Abstract : This doctoral thesis is devoted to studying the possibilities of using additive manufacturing (AM) and design based on computed tomography (CT), for the production of patient-specific implants within orthopedic surgery, initially in a broad perspective and, in the second part of the thesis focusing on customized clavicle osteosynthesis plates. The main AM method used in the studies is the Electron Beam Melting (EBM) technology. READ MORE

7. 20. On Characterization and Optimization of Surface Topography in Additive Manufacturing Processes

   Author : AMOGH VEDANTHA KRISHNA; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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. READ MORE
