In this work the mechanical characterisation of fused filament fabricated non-reinforced polylactide and polylactide reinforced with short carbon fibre laminate after environmental aging was reported. In the manufacturing process, the symmetric laminate was used to determine the influence of environmental aging of 3D printed parts. The sterilisation agents and buffered saline solution environment were used as aging factors. Also, the fracture surfaces of non-reinforced and reinforced specimens were imaged with scanning electron microscopy. It was found that short carbon fibres in general influence the higher mechanical strength of materials compared to materials without fibres. But at the same time the addition of short carbon fibre influence of significant loos of toughness when aged with sterilisation agents and buffered saline solution environment during one, six or twelve weeks. The results presented in this work are important for several reasons. The study highlights how the addition of short carbon fibres enhances the mechanical properties of polylactide (PLA), which is valuable for applications requiring increased strength and stiffness, while also addressing the impact of environmental aging, particularly in sterilization and buffered saline solution environment.This is crucial in understanding the mechanical behavior of these materials, as many PLA applications (e.g., in medical devices or marine environments) involve exposure to conditions like mentioned above. Understanding how aging affects a material's mechanical properties helps project lifetime and reliability of products.
