Thanks to its ability to facilitate easy fabrication of complex-shaped parts using low-cost
supplies and compact equipment, 3D printing has rapidly advanced and seamlessly integrated into the
daily lives of even ordinary individuals. In recent years, although a wide variety of filament materials
have been introduced for ordinary applications in the method, PLA and ABS still stand out as the most
commonly used materials. Despite its many superior features, PLA's brittleness and relatively low
mechanical and thermal resistance make ABS a preferred choice for longer-lasting end products. The
adoption of ABS is crucial, as it offers improved durability and addresses the limitations of PLA,
contributing to the overall enhancement of product lifespan. Thus, the utilization and development of
materials based on ABS are of paramount importance in the realm of 3D (three-dimensional) printing. In
this study, uniaxial tensile and three-point bending tests were conducted to assess mechanical
performance of PC/ABS (Polycarbonate/Acrylonitrile Butadiene Styrene) blend used as a filament
material in the 3D printing process. Additionally, Double Edge Notched Tensile (DENT) specimens were
produced via 3D printing in accordance with the EWF (Essential Work of Fracture) method. The results
of the EWF analysis were scrutinized, considering the inherent nature of the method. According to
calculations made for suitable ligament (L) lengths, the material's fracture toughness was determined to
be 24 kJ/m
