This paper presents an open access data repository of mechanical properties after weathering for AM plastics, conventionally manufactured plastics, and for two clear protective coatings. All materials were exposed to a 1500-h accelerated weathering cycle (ISO-4982-3) followed by tensile testing (ISO-527). Special attention was given to polyamide 12 (PA12) produced via powder bed fusion AM in two build orientations. The fracture surfaces of PA12 and glass-filled PA12 were further studied with scanning electron microscopy. The AM materials were PA12, glass-filled PA12, and carbon reinforced PA12. Traditionally manufactured materials included glass-filled and molybdenum disulfide-filled PA66, PMMA, ABS, PC, and cast PA12.
No clear differences were found between the AM build orientations in fracture mechanisms or weathering performance. AM and cast PA12 were strongly affected by accelerated weathering. Carbon reinforced PA12 with a UV varnish experienced the least changes. Weathering resistance was increased with protective coatings. However, an increase in the deviation of mechanical properties with the coatings was observed. The contrary results in ductility for the glass-filled and molybdenum disulfide-filled PA66 after weathering would merit further studies.
