Porosity in laser-sintering with continuous fibers; [Prozess-Struktur-Eigenschaftsbeziehungen des Laser-Sinterns mit Endlosfaserverstärkung Fehlstellen im Laser-Sintern mit Endlosfasern]

Additive manufacturing of continuous fibrereinforced plastic components (CFRP) enables the cost-effective production of complex components for various industries. Laser sintering as a process has only recently been enabled for the production of CFRP. While the integration has been validated, the mechanisms behind the process are not yet fully understood. In this paper, first influences of the process parameters on the resulting porosity are presented in order to investigate the process-structure-property relationships as the key to process optimisation.
