The Impact of Multifunctional Polysiloxanes on Enhancing the Properties of Polyethylene Terephthalate Glycol (PET-G) for FDM/FFF 3D-Printing

The use of incremental technologies in various biomedical fields requires the development of new materials that can meet the needs of new applications. This article delves into the impact of modifying PETG with multifunctional polysiloxanes (0.10 wt.% to 2.5 wt.%) on the properties of composite materials produced for 3D printing in bioengineering applications. The article covers the effects on strength (tensile, flexural), rheological (MFR), thermal (DSC), and surface (WCA) properties. The results obtained in this study indicate that polysiloxane additives have a positive effect on the material’s elasticity and bending strength. Moreover, the results presented are a great example of interdisciplinary research combining chemical knowledge to develop specialized material applications.
