In-situ Laser Based Subtractive Manufacturing for Increased Precision of Metal Parts Produced by Laser Powder Bed Fusion KU Leuven
Laser powder bed fusion (LPBF) is an Additive Manufacturing technique which is currently in the center of focus of both academia and industry. Despite its numerous advantages, insufficient surface quality and dimensional accuracy remain major drawbacks. Furthermore, extensive post-processing is typically needed to meet the industrial requirements, which is further increasing the already high manufacturing time and cost. This work addresses ...

Tuning Process Parameters and Polymer Powder Formulation for Laser Sintering KU Leuven
Additive Manufacturing (AM), popularly known as 3D printing, is a novel group of technologies to manufacture geometrical complex parts without the need for dedicated tooling. The market of AM technologies and products has seen a consistent growth and expansion into new applications. Laser Sintering (LS) is one of the AM techniques that makes use of a laser to selectively fuse a preheated bed of thermoplastic polymer powder.

In-situ process monitoring and control of femtosecond laser machining KU Leuven
The aim is to develop process monitoring and control solutions for microscale features fabricated on metal surfaces by femtosecond laser machining. Monitoring and sensing will be conducted during the laser machining process using optics-based visualization, a displacement sensor, and acoustic emission technology. In addition, machine learning methods will be used to analyse the relation between process parameters and intended geometrical ...
Stress-Based Fatigue Behaviour of Metal Components Produced by Laser Powder Bed Fusion: Influence of Process Conditions and Post Processes KU Leuven
Laser Powder Bed Fusion (LPBF) is one of the most popular metal additive manufacturing technologies capable of manufacturing complex and intricate-shaped designs. In order to use LPBF-processed components in functional applications, their long term fatigue behaviour has to be validated. This work investigates the fatigue behaviour of metal parts produced by LPBF. More specifically, the influence of different process conditions such as heat ...
Additive Manufacturing KU Leuven
KU Leuven has been active in Additive manufacturing (AM) since 1990. The AM processes that are currently investigated in the MaPS division (Manufacturing Processes and Systems) range from LPBF (Laser Powder Bed Fusion of metal, polymer and ceramic), FFF/FPF (Fused Filament/Pellet Fabrication of metal, polymer and ceramics), SLA (StereoLithography), WAAM (Wire-arc AM), to printing of electronics and biopolymers by the use of an aerosol ...
Sensor fusion and adaptive learning for optimization and control of Wire-Arc Additive Manufacturing – with applications to functionally graded materials KU Leuven
A niche research trend in advanced materials is the creation of materials that are non-isotropic or graded in single or multiple directions of a component, which is referred to as functionally graded materials (FGM). Directional material properties are seen in nature in various forms and this can be utilized in engineering applications where a gradation in thermal, mechanical or tribological properties are required. FGMs can be created with ...
