  2. 1. Manufacturing capabilities : expendable commodities or catalysts for effective supply chain management

    Author : Robin von Haartman; Lars Bengtsson; Matti Kaulio; Björge Timenes Laugen; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : Many large companies have for a long time been very successful in their industries by combining leading edge R&D and marketing with strong internal manufacturing capabilities. An alternative model is now getting increased attention, where R&D and marketing is conducted internally and manufacturing performed by outsourcing partners. READ MORE

  4. 2. 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; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; Space Industry; Surface Roughness; Design for Additive Manufacturing; DfAM; Laser Powder Bed Fusion; Produktinnovation; Product Innovation;

    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

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

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

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

  7. 5. Low Frequency Impact Sound in Timber Buildings : Transmission Measurements and Simulations

    Author : Jörgen Olsson; Andreas Linderholt; Börje Nilsson; Carl Hopkins; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Timber floors; FE-simulations; Light weight floors; Frequency response functions; Building acoustics; Byggteknik; Civil engineering;

    Abstract : An increased share of multi-story buildings that have timber structures entails potential in terms of increased sustainability as well as human-friendly manufacturing and habitation. Timber buildings taller than two stories were prohibited in Europe until the 1990s due to fire regulations. In 1994, this prohibition was removed in Sweden. READ MORE
