1. A method of additively manufacturing a composite tube, comprising:
storing a finite length of a prefabricated sleeve within a print head;
wetting the prefabricated sleeve with a liquid matrix;
discharging the prefabricated sleeve from the print head;
moving the print head during discharging such that the composite tube has a three-dimensional trajectory; and
directing a cure energy onto the prefabricated sleeve to cure the liquid matrix during discharging from the print head.
