   Abstract : Local treatment of a tumour is of interest from a number of perspectives. It is focused on reducing the tumour volume with minimal trauma, inducing tumour immunity and is a potential component of a combination therapy against tumours. READ MORE

6. 4. Additive metallurgy - Thermal influences on structure and properties of stainless steel 316L

   Author : Jon Olsén; Zhijian James Shen; Dongdong Gu; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Additive manufacturing; Selective laser melting; Electron beam melting; Hot isostatic pressing; Stainless steel; Microstructural heterogeneity; Materials Chemistry; materialkemi;

   Abstract : Additive manufacturing (AM) as a manufacturing process has, in recent years, become widely accepted as capable of manufacturing parts that will be used in end products. In this thesis, stainless steel grade 316L parts are manufactured using two different powder bed fusion techniques, selective laser melting (SLM) and electron beam melting (EBM). READ MORE

7. 5. Additively Manufactured Inconel 718 : Microstructures and Mechanical Properties

   Author : Dunyong Deng; Johan Moverare; Ru Lin Peng; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Additive manufacturing (AM), also known as 3D printing, has gained significant interest in aerospace, energy, automotive and medical industries due to its capabilities of manufacturing components that are either prohibitively costly or impossible to manufacture by conventional processes. Among the various additive manufacturing processes for metallic components, electron beam melting (EBM) and selective laser melting (SLM) are two of the most widely used powder bed based processes, and have shown great potential for manufacturing high-end critical components, such as turbine blades and customized medical implants.
