Evaluation of fatigue properties of 3D-printed Polyamide-12 by means of energy approach during tensile tests

Rapid prototyping and Additive Manufacturing are experiencing a continuous and rapid growth in different industrial fields, ranging from automotive to biomedical applications. They allow the creation of a wide range of devices in a short time with several materials, such as polymers and metals. On the other hand, the manufacturing process considerably affects the performance of the obtained 3D-printed materials and different laboratory tests are required in order to assess the mechanical properties, especially the fatigue behavior, of these materials. The present work is the result of the collaboration between the Engineering Department of the University of Messina and the rapid-prototyping company Skorpion Engineering. The aim of this work is to apply, for the first time on 3D-printed materials, the Static Thermographic Method for the fatigue assessment of Polyamide-12. (C) 2020 The Authors.
