Simplification of fused deposition modeling 3D-printing paradigm: Feasibility of 1-step direct powder printing for immediate release dosage form production

Direct powder three-dimensional (3D)-printing (DPP) of tablets to simplify fused deposition modelling (FDM) was explored. The FDM paradigm involving hot-melt extrusion for making 3D-printable drug-loaded filaments as intermediate products for tablet manufacturing has been gaining attention for the decentralized on-site production of personalized dosage forms. For direct 3D-printing, powder blends were loaded into a cartridge-like head and were...
