FIELD: chemistry.
SUBSTANCE: invention relates to a method for additive production of a composite structure. Technical result is achieved by additive production of composite structure, which includes direction of continuous reinforcing component part in print head, as well as coating of continuous reinforcing component part with first matrix component inside printing head and coating with second matrix component, which differs from first matrix component. Then, the continuous reinforcing component is discharged through the nozzle of the printing head during movement of the printing head in many directions. First and second matrix components interact to cause matrix hardening around the continuous reinforcing component. First matrix component is a resin. Second matrix component is one of catalyst, curing agent and initiator. Coating of continuous reinforcing component by second matrix component is its coating inside printing head by second matrix component after coating with first matrix component.
EFFECT: technical result is higher strength and avoiding sag.
