A system and method for manufacturing composite parts has been developed which offers the ability to produce composite parts in an infusion resin process without the use of expensive preforms or tools. In addition, the methods of manufacturing composite parts described herein offer the ability to produce composite parts having complex structures without the need for complex tooling. The method of manufacturing and systems described herein typically include printing a part skeleton using an additive manufacturing process followed by infusing the part skeleton with resin and curing the resin infused part skeleton to form the composite part. Un système et une méthode de fabrication de pièces composites ont été élaborés pour offrir la capacité de produire des pièces composites selon un procédé dinfusion de résine sans utiliser des préformes ou des outils dispendieux. De plus, les méthodes de fabrication de pièces composites décrites offrent la capacité de produire des pièces composites ayant des structures complexes sans recourir à des outils complexes. La méthode de fabrication et les systèmes décrits comprennent généralement limpression dun squelette de pièce au moyen dun procédé de fabrication additive suivi de linfusion dune résine dans le squelette et le traitement du squelette pour former la pièce composite.
