Description
Summary:Fused Deposition Modelling (FDM) along with other Additive Manufacturing (AM) processes are used today in a large number of applications among which those dedicated to the medical field are focused on manufacturing anatomical models, surgical devices, implants or prostheses. While anatomical models are mainly manufactured for patient communication, visualization, surgery training, rehearsal or simulation, there are also 3D printed medical objects that come in contact with the patient body tissues and fluids. Therefore, in their case sterilization and biocompatibility testing are mandatory steps before use. In this context, the current paper is studying the influence of sterilization on the compressive strength of FDM objects, as well as on their dimensional accuracy. Standard samples for evaluating the compressive strength of FDM objects manufactured from ABS (Acrylonitrile-butadiene-styrene) material were used. For assessing the dimensional accuracy, a test part was designed, manufactured and sterilized. The test part was measured before and after sterilization, a comparison with the virtual part being made. The results of this study can be used by designers as they provide valuable information on how to design 3D printed parts.
