Evaluating Swellable Cross-Linked Biopolymer Impact on Ink Rheology and Mechanical Properties of Drug-Contained 3D-Printed Thin Film - Pharma Excipients

Abstract Background/Objectives: Interest in 3D printing oral thin films (OTFs) has increased substantially. The challenge of 3D printing is film printability, which is strongly affected by the rheological properties of the ink and having suitable mechanical properties. This research assesses the suitability of sodium starch glycolate (SSG), a swellable cross-linked biopolymer, on ink rheology and the film’s mechanical properties. Methods: A wate…
