Short-term Creep Behaviour of Different Polymers Used in Additive Manufacturing under Different Thermal and Loading Conditions

Polymer materials produced by additive manufacturing undergo significant changes in their dimensions under continuous loading conditions. This situation affects the operation of polymer structures within safe limits. Therefore, it is crucial to determine creep behaviour polymers method. study investigates six different materials, acrylonitrile butadiene styrene (ABS), chlorinated polyethylene (CPE), polylactic acid (PLA), tough (TPLA), polycarbonates (PC), and nylon most commonly used manufacturing. The test specimens are firstly with a three-dimensional (3D) printer, then final given using computer numerical control (CNC) milling. experiments carried out at three ambient temperatures (25 °C, 40 60 °C) two stress levels (10 MPa, 20 MPa). According results, was determined that material type, temperature, significantly influenced 3D printed materials.
