Material Extrusion-Debinding-Sintering as an Emerging Additive Manufacturing Process Chain for Metal/Ceramic Parts Construction KU Leuven
Material Extrusion of metal/ceramic-polymer filaments for the construction of, respectively, metal or ceramic parts, has raised great interest among the research community during the last five years. It usually comprises three main phases: printing, debinding and sintering. With respect to other metal/ceramic Additive Manufacturing (AM) technologies, the benefits are several: simplicity, enhanced safety during use, material and costs saving. The ...
Production and characterisation of filament-based Material Extrusion (MEX) additively manufactured copper parts KU Leuven
Material Extrusion (MEX) Additive Manufacturing of metal components is increasingly applied in recent years due to its low cost and potential for multi-material printing, with filament-based MEX being widely developed among all subdivisions of MEX. This technology utilises a compounded filament of polymeric binders and metal powder. The printing process involves hot extrusion of the compounded filament, which acts as a carrier of the metal ...
Mould manufacturing by hybrid laser powder bed fusion of M789 steel on a functional base KU Leuven
This research focuses on reducing the manufacturing cost of metal components through “hybrid additive manufacturing”, i.e. laser powder bed fusion (LPBF) carried out on a pre-machined functional base. By incorporating part of the final component's geometry (such as cooling channels) in the base, the cost for large and bulky products can be minimized. The study identifies two crucial quality requirements for such a hybrid process: (1) reaching ...
Thermal analyses and characterisation of fused filament fabrication KU Leuven
Fused filament fabrication (FFF) is the most accessible 3D printing or additive manufacturing technology to the general public and professional customers. It has been increasingly used in daily life, as well as primary, secondary and higher education, and industries such as automotive, aerospace and medicine. FFF employs a thermoplastic filament to fabricate a 3D part in an additive manner, typically strand-by-strand and then layer-by-layer. ...
