printing are attracting wide spread interest due to easily accessible with
lower cost. The present paper aims to investigate printing occupancy rates
effect on mechanical properties and surface roughness of PET-G (Polietilen
Tereftalat Glikol) material products. Pet-G material was preferred because of
its <a href="http://tureng.com/en/turkish-english/malleability"> <span style="color:#000000;">malleability </span> </a>,
colorability and mechanical properties. PET-G products were printed at
different printing occupancy rates (20%, 50% and 80%) at processing speed of 45
mm/s and all other operating parameters fixed at the same conditions on 3D
printer. Uniaxial tensile tests, hardness measurements and surface roughness
measurements of the printed products were carried out. The results were
analyzed and compared </span> </em> <em>. </em> </p> <p> <em> </em> </p> <em> </em>}, number={2}, publisher={Tokat Gaziosmanpasa University} }
