Abstract :Today, fused deposition modeling insert ignore into journalissuearticles values(EMM);, which is one of the additive manufacturing methods, can transform the highlighted ideas into three-dimensional products after their designs. For this reason, it is frequently preferred in many platforms, from applications in aerospace and aviation to the construction of houses in the construction industry and the production of parts as a hobby. In this study, the influence of the taper angle insert ignore into journalissuearticles values(ϴ=0, ϴ=0.25 ve ϴ=0.50); and boundary conditions insert ignore into journalissuearticles values(narrow or wide side is fixed); on the natural frequency values of the tapered Polyethylene terephthalate glycol insert ignore into journalissuearticles values(PET-G); beams that are manufactured with fused deposition modeling insert ignore into journalissuearticles values(FDM); was determined by both experimental and Ansys APDL finite element analysis program and compared between each other. In addition, in order to experimentally determine the elasticity modulus values that should be assigned as material data in the finite element analysis program, tensile test samples were produced with the same FDM parameters, in accordance with the ASTM D638 standard, and the relevant samples were subjected to the tensile test. In addition to these, hardness and surface roughness measurements were also carried out from the produced samples. As a result, it has been determined that the natural frequency values increase with the increase of the taper angle from 0.25 to 0.50 in the tapered beams produced by FDM and when the fixing is applied from the wide edge compared to the narrow edge. The finite element analysis results and the experimental results are in good agreement.
