Since the development of 45S5 bioactive glass, known as the first bioactive resorbable glass, many different compositions have been explored over the years [1, 2]. Those glass compositions can be used to create scaffolds for bone tissue engineering [3]. Scaffolds need to fulfill various requirements to support the complex biomechanical and biological system of bone tissue. They need to be biocompatible, bioresorbable and exhibit a certain pore size while retaining their mechanical properties [3]. In order to improve the mechanical properties of bioactive glass-based scaffolds, the aim of this bachelor thesis is to create glass-polymer filaments to be used in 3D printing of scaffolds via fused deposition modeling.
