Abstract:

Bio-based binder alleviate the important carbon footprint that is created during PIM-like process with a carbon cycle for the binder. Moreover, some bio-based polymer are more suited to EAM, like PLA.This work presents the different steps in developing a suitable pellets feedstock for PIM-like EAM and its optimisation to minimize porosity by tomographic observation in the final part. The work is focused in the use of a steel-tool alloy powder but using the same method other materials can broaden the field of application.
