Microneedles (MNs) are a rapidly emerging technology for user-friendly and minimally invasive drug delivery and biological fluid sampling applications [1]. Simple, low-cost and reproducible fabrication of microneedle arrays (MNAs) with optimal MN designs is pivotal for their widespread adaptation. Additive manufacturing or 3D printing is a viable strategy for production of MNAs with considerably improved design flexibilities compared with conventional manufacturing methods [2,3]. Here, we discuss 3D printing of MNAs toward enabling several clinical applications.
