Chapter 4

Synthetic Polymers for HME-Based 3D Printing

This chapter focuses on synthetic polymers that have been used either individually or in combination as the matrix materials or plasticizers for fused deposition modeling (FDM) 3D printing. The polymers used for hot melt extrusion (HME) theoretically can be utilized for FDM 3D printing. However, the melt viscosity should be carefully considered as 3D printing is more limited by the printers where the printing tip orifice size is usually small. Plasticizers are usually combined with the matrix polymers to lower the melt viscosity and the printing temperature. Sometimes, functionalities are required to achieve different release patterns, for example, sustained release, delayed release, or instant release. In this chapter, the applications of Soluplus®, Kollidon® IR, Kollidon® SR, Kollidon® VA64, and soluble Kollidon® in FDM 3D printing are summarized.

Chapter 6

API and Polymer Selection: Formulation and Process Variables

Successful 3D printability depends on various critical parameters. During formulation, ensuring the stability of the active pharmaceutical ingredient (API) while processing and within the 3D-printed dosage forms entails critical components. The major challenge in stability is preserving the API’s physical (crystalline or amorphous) nature. While hot-melt extrusion (HME) offers amorphization of the API, the challenge lies in maintaining the active’s physical and chemical stability, such as the risk of degradation at elevated temperatures. Balancing API-polymer miscibility and leveraging non-covalent interactions become integral strategies for stability. Comprehensive analytical methodologies and real-time monitoring techniques provide valuable tools for stability assessment during formulation and product development. By selectively incorporating plasticizers, antioxidants, and optimal processing parameters, coupled with stringent storage protocols, the journey toward consistent, top-tiered 3D-printed pharmaceutical products is introduced and discussed within this chapter.
