1. 11. Construction of a Heat Transfer Rig based on Energy Balance for Rapid Production of Correlations for Additively Manufactured Geometries

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Joaquin Quesada Zeljkovic; [2019]
   Keywords : ;

   Abstract : This thesis has set the first milestones towards building a Nusselt number correlation that adapts to the current state of art designing and manufacturing processes at Siemens Industrial Turbomachinery AB, focusing on cooling mini-channels produced with Additive Manufacturing.  Additive manufacturing (AM), also known as 3D printing, is a gamechanger technology that has revolutionised manufacture and design know-how, bringing down production cost, time and waste.

3. 12. Powder bed additive manufacturing using waste products from LKAB's pelletization process : A pre-study

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Gabriella Brandemyr; [2019]
   Keywords : LKAB; powder; AM; waste products;

   Abstract : This report is the result of a bachelor thesis project executed at Luleå University of Technology(LTU). The purpose of the project was to investigate the possibility to use the metal powder wasteproducts from LKAB’s pelletizing process for additive manufacturing as this would meaneconomic benefits for the sake of LKAB as well as environmental benefits.

4. 13. Alloy 718 manufactured by AM Selective Laser Melting : Evaluation of microstructure and weldability

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Valeri Ivanov Petkov; [2018]
   Keywords : Inconel 718; Selective Laser Melting; Additive Manufacturing; Heat Treatment; Weldability;

   Abstract : Inconel 718 is one of the main superalloys that are used in hot structures of jet engines today, because of its excellent mechanical properties at high temperatures and its good weldability. This material has been extensively used and studied in cast and wrought forms during the past decades. READ MORE

5. 14. Residual stresses and distortions in austenitic stainless steel 316L specimens manufactured by Selective Laser Melting

   University essay from Högskolan Väst/Avdelningen för svetsteknologi (SV)

   Author : Henrik Nöbauer; [2018]
   Keywords : Residual Stresses; Distortions; SLM; Selective Laser Melting; 316L; X-ray diffraction; XRD; ESPI; Hole drilling;

   Abstract : Residual stresses are one of the major challenges in additive manufacturing of metallic materials today. They are induced during manufacturing because of the rapid local heating and cooling and may cause distortions, cracking and delamination between layers. READ MORE

6. 15. A Cost Breakdown and Production Uncertainty Analysis of Additive Manufacturing : A Study of Low-Volume Components Produced with Selective Laser Melting

   University essay from Blekinge Tekniska Högskola/Institutionen för industriell ekonomi

   Author : Jonas Barsing; [2018]
   Keywords : Production uncertainty; Product cost; Additive manufacturing; Cost estimation; AM; Produktionsosäkerheter; produktkostnad; additiv tillverkning; kostnadsuppskattning; AT;

   Abstract : Background: Additive manufacturing has recently gained cogency as a final part manufacturing technique. The method uses a layer-upon-layer technique to build three-dimensional objects. This technique has many advantages creating new opportunities regarding production. READ MORE
