An additive-manufacturing system for forming at least one non-woven fibrous implant (10000, 11000, 12000), comprising: a robotic subsystem including: scanning and imaging equipment configured to scan a patient's anatomy; and an armature including at least one dispensing nozzle configured to selectively dispense at least one rigid material and at least one pliable material; a controller apparatus having a processor and a non-transitory computer-readable medium storing computer-executable instructions configured to, when executed by the processor, cause the controller to: send a control signal to control the scanning and imaging equipment to determine a target alignment of a patient's spine; develop an additive-manufactured printing plan including an additive-manufactured material selection plan based on the target alignment of the patient's spine; and execute the additive-manufactured printing plan to: control the armature to dispense the at least one material chosen from the at least one rigid material and the at least one pliable material to form a non-woven fibrous component, wherein the non-woven fibrous component defines a plurality of randomly oriented fibers further defining a plurality of open pore spaces between adjacent fibers configured to facilitate boney ingrowth between adjacent fibers. a robotic subsystem including: scanning and imaging equipment configured to scan a patient's anatomy; and an armature including at least one dispensing nozzle configured to selectively dispense at least one rigid material and at least one pliable material; scanning and imaging equipment configured to scan a patient's anatomy; and an armature including at least one dispensing nozzle configured to selectively dispense at least one rigid material and at least one pliable material; a controller apparatus having a processor and a non-transitory computer-readable medium storing computer-executable instructions configured to, when executed by the processor, cause the controller to: send a control signal to control the scanning and imaging equipment to determine a target alignment of a patient's spine; develop an additive-manufactured printing plan including an additive-manufactured material selection plan based on the target alignment of the patient's spine; and execute the additive-manufactured printing plan to: control the armature to dispense the at least one material chosen from the at least one rigid material and the at least one pliable material to form a non-woven fibrous component, wherein the non-woven fibrous component defines a plurality of randomly oriented fibers further defining a plurality of open pore spaces between adjacent fibers configured to facilitate boney ingrowth between adjacent fibers. send a control signal to control the scanning and imaging equipment to determine a target alignment of a patient's spine; develop an additive-manufactured printing plan including an additive-manufactured material selection plan based on the target alignment of the patient's spine; and execute the additive-manufactured printing plan to: control the armature to dispense the at least one material chosen from the at least one rigid material and the at least one pliable material to form a non-woven fibrous component, wherein the non-woven fibrous component defines a plurality of randomly oriented fibers further defining a plurality of open pore spaces between adjacent fibers configured to facilitate boney ingrowth between adjacent fibers.
