Abstract

Additive manufacturing offers manufacture of personalised pharmaceutical tablets through design freedoms and material deposition control at an individual voxel level. This control goes beyond geometry and materials choices: inkjet based 3D printing enables the precise deposition (10-80 μm) of multiple materials, which enables integration of precise doses with tailored release rates; in the meanwhile, this technique has demonstrated its capability of high-volume personalised production. In this paper we demonstrate how two dissimilar materials, one water soluble and one insoluble, can be co-printed within a design envelope to dial up a range of release rates including slow (0.98 ±0.04 mg/min), fast (4.07 ±0.25 mg/min) and multi-stepped (2.17 ±0.04 mg/min then 0.70 ±0.13 mg/min) dissolution curves. To achieve this, we adopted poly-4-acryloylmorpholine (poly-ACMO) as a new photocurable water-soluble carrier and demonstrated its contemporaneous deposition with an insoluble monomer. The water soluble ACMO formulation with aspirin incorporated was successfully printed and cured under UV light and a wide variety of shapes with material distributions that control drug elution was successfully fabricated by inkjet based 3D printing technique, suggesting its viability as a future personalised solid dosage form fabrication routine.
