Effectively thermal conduction pathways are essential for achieving high conductivity (TC) in polymer-based composites. While constructing a segregated structure can yield TC with low filler loadings, traditional processing methods often have inherent drawbacks, typically involving complex preparation process and reduced mechanical performance. In this study, free-form was constructed based on the full advantages of 3D printing. The composite dense prepared by printing scaffold followed filling thermally conductive then hot pressing. Furthermore, boron nitride (BN) chosen as electrical insulating model, while graphene (GR) served model. Benefiting from interconnected network, 3D-printed composites GR exhibit 3.82 W/mK, representing 2.81 times that randomly blended fillers. Concurrently, these also demonstrated robust properties, tensile strengths up to 20.3 40.6 MPa, respectively, signifying substantial improvements 1.83 3.98 over their counterparts. Therefore, strategy provides way easy, effective, universal suitable various insulated or electronic devices.
