En faisant varier l&rsquo;\u00e9tat initial du mat\u00e9riau gr\u00e2ce \u00e0 diff\u00e9rents syst\u00e8mes de fabrication additive et param\u00e8tres de processus, les limites du pressage isostatique \u00e0 chaud sont explor\u00e9es.

Les diff\u00e9rences dans les attributs du mat\u00e9riau, comme les d\u00e9fauts ou la microstructure, n&rsquo;expliquent pas enti\u00e8rement les variations de performance, ce qui sugg\u00e8re que d&rsquo;autres facteurs peuvent entrer en jeu.
