3D printing is an additive manufacturing technique and materials are deposited layer by layer. This allows the design of solid dosage forms and personal medicines. The current 3D printing technique that we are using is fused deposition modelling (FDM) which is a thermodynamic pathway of producing amorphous and amorphous solid dispersion (ASD). We use hotmelt extrusion to prepare ASD filaments and print solid dosage forms using 3D printer. Currently, we are combining knowledge in amorphous pharmaceutics, formulation, solid-state characterisation and pharmaceutical technology to develop personalised medicines.
