Influence of particle surface roughness on inter-particle forces
Particle surface roughness is linked with the inter-particle forces that are governing cohesion phenomena at powder level such as flowability, a key element in the processability in many industries such as pharma, food and even manufacturing.
Additive Manufacturing (AM) has shown outstanding capabilities to revolutionise the manufacturing industry. It is nowadays present in many industrial environements, especially as laser sintering (for polymers) and laser melting (for metals): for this reason, many materials have been launched over the years in order to enhance performances and add functionalities to AM parts. Typical feedstock for industrial AM are powders, both metallic and polymeric, and understanding of powder processability is mandatory for a successful scale-up of this family of technologies.

**All very nice and interesting, but what am I going to do?**
The goal of this project is to build up solid knowledge about evaluation of surface roughness on powdered materials such as the ones used in additive manufacturing. This includes sample preparation, data acquisition using one or more different devices, and data evaluation using Python/Matlab. Correlation with an existing database of measurements and/or discrete element methods (DEM) simulation will conclude the work, in case of a thesis.
