In this context, parts were produced by Stereolithography (SLA) and Fused Deposition Modelling (FDM) methods. The mechanical properties of the produced materials were determined by tensile test according to ASTM D638 standard. Afterwards, these parts were bonded in different combinations and the mechanical properties of the joints were determined according to ASTM D1002 standard. As a result, the tensile strength of Polylactic Acid (PLA) parts produced by FDM method was 65% higher than that of PhotoPolymer Resin (PPR) parts produced by SLA method, while the strain rates of PPR materials were 85% higher than PLA materials. When the failure load values obtained after the tensile test of the bonded joint specimens were examined, the best mechanical performance was obtained as 3086 N in the combination of PLA and composite material. The lowest damage load occurred in the combination of PPR and PLA material. When the displacement data resulting from the failure load were analysed, the highest values were obtained in the PPR-PPR material combination. In conclusion, bonding can be used for joining parts produced by additive manufacturing, but the choice of material should be based on the application.}, number={1}, publisher={Mustafa GÜNAY}
