Abstract Additive manufacturing (AM) is an advanced technique to fabricate a complex geometrical structure using polymer, metals, ceramics, and composite materials. Fused filament fabrication (FFF) the most widely used extrusion‐based AM manufacture polymer parts. Continuous carbon fiber (CCF) lightweight high‐strength material that offers exceptional mechanical durability performance when incorporated with polymers; it significantly enhances their performance. To print continuous fibers extrusion technique, various methods have been adapted according technology. In this study, self‐developed co‐extrusion towpreg method was employed composites in which both materials matrix CCF reinforcement were inserted separately extruded together through single nozzle. Two important printing process parameters (layer height line width) considered different ranges investigate influence on properties (tensile, flexural, shear compressive), air void volume, volume fraction. The results obtained demonstrate significant impact are mostly influenced by layer of samples. group specimens 0.4 mm width 1.0 showed highest tensile, shear, compressive strength 372.68, 247.59, 42.83, 184.19 MPa, respectively, minimum 13.84%. Furthermore, research outcomes highlight can be optimized adjusting parameters. Highlights Co‐extrusion CCFRTC.
