Abstract
In this study, two commercial flexible polymers which have different components inside were used to manufacture cylindrical scaffolds for experiments via fused deposition modelling. One of the purposes of this study is to show that scaffolds can be produced using flexible filaments with FDM machine. The second one is to contribute to literature about the tribological properties of the polymeric scaffolds. Additive manufacturing has been widely used in many areas to manufacture prototypes, toys, even real products. Polymers are main materials used in the additive manufacturing systems to obtain light weight products. Samples for the experimental work has been produced via FDM system successfully as a cylindrical shape. Wear and friction properties of the flexible polymers were investigated using pin-on-disc test device. Diameter and hardness of the samples were measured. Effects of load variations and material differences on the tribological characteristic of samples was observed. Even these two polymers have the similar base material, due to small component differences between these filaments, significant differences were observed on hardness and coefficient of friction (COF) values. Similar graph profile was obtained from the pin-on-disk device, but small variations were observed on COF values when using the same material under different load values. However, there were significant differences between COF of two material under the same load. Similar situation can be said for hardness values. The cylindrical shape scaffolds were produced successfully from the flexible polymers using FDM system. And so tribological properties of the samples produced via FDM were observed. As far as we know that there is a lack of tribological studies of flexible polymer in the literature. We believe that this study can provide some useful knowledge to the literature.
