SuPreAM in a nutshell

Boosting the implementation of Additive Manufacturing with optimal surface integrity


The SuPreAM project is developing and improving the performance and capabilities of a predictive simulation model of finishing operations in steel Additive Manufacturing (AM). 

SuPreAM has the objective to optimise the surface integrity of Additive Manufactured and Machined steel components and to reduce manufacturing expenditures at the steel industrial sector by minimising the material scrap and reducing the number of re-processing loops during finishing operations.  

The excellence of SuPreAM relies on the integration of all the factors affecting surface integrity generation over additive manufactured workpieces in order to provide machining strategies solutions in the design stage, prior workpiece finishing, avoiding the generation of scrap, aiming to produce defect free components.
