Figure Lengend Snippet: Schematic illustration of the fabrication of 3D-printed liquid capsule. A dual-head 3D printer was modified by replacing the right-hand nozzle with a syringe dispenser. The FDM nozzle head was loaded with HME processed API-free filament of immediate or extended-release properties whilst drug solution or suspension were dispensed using syringes of variable sizes and nozzle diameters.

Figure Lengend Snippet: The optimized result of PMMA microchannel with an orthogonal method. ( a ) A factor response figure of the orthogonal method. Ai was the factor of nozzle temperature, Bi was the factor of printing speed, and Ci was the factor of layer height. The line was steeper; the influence of the factor was greater. ( b ) Roughness value with optimized 3D-printed parameter. ( c ) Microchannel profile waviness with optimized 3D-printed parameter. The waviness characterized the microchannel surface planarity. ( d ) The micrograph of the optimized microchannel profile using metallographic microscopy (scale bar: 100 μm).
