additive manufacturing, agreement title french : Vers un jumeau numérique de l’épandage de poudre dans la fabrication additive par fusion au laser sur lit de poudre, agreement number : 1014629, agreement value : 203500.0, agreement start date : 2024-02-21, agreement end date : 2026-01-31, description english : Powder spreading in laser powder bed fusion (LPBF) is crucial for part 
quality and process productivity but is plagued by issues associated with the 
very specific flow of fine metal powders, and the lack of understanding of the 
interactions that dictate powder dynamic behavior.
To address these challenges, the research team aims to develop a 
numerical model using the Discrete Element Method (DEM) to simulate the 
powder spreading process in LPBF. This model will help assess the impact 
of powder properties on bed quality and assist in designing more efficient 
recoaters and developing new metal powder feedstocks. The Project's 
objectives include improving instrumentation for assessing metal powder bed 
surface quality, developing a protocol for extracting powder behavior model 
parameters, refining and validating a numerical model for additive 
manufacturing (AM) powder spreading, and extending the digital twin model 
to include deformable and flexible recoater designs. This comprehensive 
approach can enhance powder spreadability, thereby contributing to 
advance LPBF technology in the additive manufacturing AM field., description french : Vers un jumeau numérique de l’épandage de poudre dans la fabrication additive par fusion au laser sur lit de poudre, expected results english : In the short term, anticipated outcomes will be strengthened collaborations across industry, academia, and government to support research excellence.
