Additive manufacturing represents an alternative that offers great advantages in small-scale production, high level of customization and ease of building complex geometries. However, rapid prototyping parts present mechanical limitations that prevent their use in applications that require greater resistance. In the present work an experimental analysis was carried out where the processes of Resin Infusion and Hand Lay-Up were compared, performing tests with specimens constructed according to the ASTM D790-17 standard, for laminated material of carbon fiber with plastic nuclei by prototyping fast and tested with two orientations of fibers "3k", (-45o +45o and 0o 90o). The tests and the statistical analysis of the data were made based on a factorial design, generating results that offer acceptable levels of stiffness and deflection without causing delamination failures, obtaining a combination that allows the manufacture of a piece without the need for a mold. The material constructed by Hand Lay-Up offered the best performance, by not failing by delamination.
