  2. 1. Residual Stress in Additive Manufacturing : Control using orientation and scan strategies

    Author : Prabhat Pant; Ru Peng; Johan Moverare; Kjell Simonsson; Thomas Niendorf; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Residual stress; Neutron diffraction; FEM; Scan strategies; Build orientations;

    Abstract : Components with complex features that are designed with their function as a core aspect often are not viable to be manufactured with traditional methods. This has been a bottleneck in the past, leading to heavier parts with various sub-assemblies and a significant waste of material. READ MORE

  4. 2. Additive Manufacturing using Alloy 718 Powder : Influence of Laser Metal Deposition Process Parameters on Microstructural Characteristics

    Author : Andreas Segerstark; Joel Andersson; Lars-Erik Svensson; Robert Pedersen; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Laser metal deposition; powder; superalloy; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Additive manufacturing (AM) is a general name used for production methodswhich have the capabilities of producing components directly from 3D computeraided design (CAD) data by adding material layer-by-layer until a final component is achieved. Included here are powder bed technologies, laminated object manufacturing and deposition technologies. READ MORE

  5. 3. Surface Roughness Considerations in Design for Additive Manufacturing: A Space Industry Case Study

    Author : Didunoluwa Obilanade; Peter Törlind; Christo Dordlofva; Anna Rönnbäck Öhrwall; Marta-Lena Antti; Stankovic Tino; Luleå tekniska universitet; []

    Abstract : Additive Manufacturing (AM), commonly known as 3D printing, represents manufacturing technology that creates objects layer by layer based on 3D model data. AM technologies have capabilities that provide engineers with new design opportunities outside the constraints of traditional subtractive manufacturing. READ MORE

  6. 4. 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

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