Hi geert_2,
thanks for your kind answer. Now i'll try to answer your question.
The metal parts can reach density values near the base material. Just as an example, 7,7 g/cm^3 compared to 8.
The green parts requires debinding and sintering processes, that we outsourced to a proper company.
Unfortunately, the shrinkages are not always constant and they are definitely influenced by process parameters. Just to give an idea, 16/17% in X and Y axis; around 20% in Z axis.
I attached an image of green and metal part.
