1. Process development and optimization towards binder jetting of Vanadis 4 Extra
University essay from Uppsala universitet/Institutionen för materialvetenskapAbstract : Additive manufacturing (AM) has experienced significant growth and development in recent years, owing to the ability to produce complex parts using a wide range of materials with relative ease. Powder bed-based metal AM has been at the forefront of this growth, even reaching the point where parts can be manufactured for end-use applications. READ MORE

2. Additive manufacturing of lunar regolith simulant using direct ink writing
University essay from Uppsala universitet/Tillämpad materialvetenskapAbstract : In this work, the use of a lunar regolith simulant as feedstock for the direct ink writing additive manufacturing process is explored, the purpose of which is to enable future lunar in-situ resource utilisation. The feasibility of this approach is demonstrated in a laboratory setting by manufacturing objects with different geometries using methyl cellulose or sodium alginate as binding agents and water as liquid phase together with the lunar regolith simulant EAC-1A to create a viscous, printable ‘ink’ that is used in combination with a custom three-axis gantry system to produce green bodies for subsequent sintering.

3. Design of cemented carbide with Ni-based superalloy binder strengthened with y’-Ni3Al precipitates
University essay from KTH/MaterialvetenskapAbstract : Replacement of cobalt in cemented carbides has gained in attention recently because threats of regulations due to health issues (cancerogenic effect), increased demand from the electric vehicle industry and the questionable extraction from countries like Democratic Republic of Congo. In this report the use of Ni-based binder as an alternative binder for cemented carbides has been explored. READ MORE

5. Additive Manufacturing of Silicon Nitride
University essay from Luleå tekniska universitet/MaterialvetenskapAbstract : This study aims to investigate the fabrication of silicon nitride ceramics via additive manufacturing method. Silicon nitride exhibits excellent thermo-mechanical properties and it is one of the main structural ceramics. The excellent properties of silicon nitride are obtained through densification via liquid phase sintering. READ MORE
