(267) Nano vs. Micro: Impact of Drug Particle Size in Extrusion-based 3D Printing on Tablet Performance

Semi-solid extrusion (SSE) 3D printing has emerged as a promising technique for the fabrication of personalized pharmaceutical dosage forms [1]. Despite its potential, the influence of ink properties, particularly the incorporation of solid drug particles, on the quality of printed tablets has not been thoroughly studied. This research aims to evaluate the effect of solid drug particle size within the ink formulations on the printing fidelity and structural integrity of porous 3D-printed tablets.
