Beschreibung
Zusammenfassung:	The invention relates to a liquefier tube (100) for an Additive Manufacturing system, comprising a body (101) provided with a feed channel (109) comprising a feeding portion (102) having a first diameter, an outlet portion (104) having a second diameter, the first diameter being larger than the second diameter, and a transitional portion interconnecting the feeding portion and the outlet portion. Said transitional portion has a decreasing third diameter from said first diameter to said second diameter, and an inner surface of said transitional portion is provided with a plurality of ribs. The invention further relates to methods of manufacturing said liquefier tube. L'invention concerne un tube de liquéfacteur (100) pour un système de fabrication additive, comprenant un corps (101) pourvu d'un canal d'alimentation (109) comprenant une partie d'alimentation (102) d'un premier diamètre, une partie de sortie (104) d'un deuxième diamètre, le premier diamètre étant supérieur au deuxième diamètre, et une partie de transition reliant la partie d'alimentation et la partie de sortie. Ladite partie de transition présente un troisième diamètre décroissant, dudit premier diamètre audit deuxième diamètre, et une surface interne de ladite partie de transition comporte une pluralité de nervures. La présente invention concerne également des procédés de fabrication dudit tube de liquéfacteur.
