We fabricated pure resin, flexible resin, resin-6.1-wt% graphite, and resin with Cu concentrations spanning from 5.5 to 15.5 wt% at different printing conditions. The structure was investigated with electron and light microscopes, and tensile testing of the printed sample was carried out. Resin temperature, post-curing temperature, and time are the dominating factors determining the strength of printed samples. Resin-Cu composite depicted a strengthening effect at 10 degrees C degrees resin and post-curing temperatures, but no strengthening effect was found for flexible resin-Cu composite at 20 degrees C degrees. Cu particles agglomerated, forming a density-graded composite; however, graphite particles distributed more homogenously in the parts. Increasing the graphite gradually reduces the composite strength. As a result, the mechanical properties of the composites are dominated by the interaction between the fillers and the matrix.eninfo:eu-repo/semantics/closedAccess3D printingStereolithographyCompositePolymerFabricationArticle392410.1557/s43578-024-01483-634623475Q3Q2WOS:0013504645000022-s2.0-85208784158
