3D Printing: A Touch-Button Approach to Manufacture Microneedles for Transdermal Drug Delivery

The document reviewed the use of 3D printing technologies for manufacturing microneedles (MNs) aimed at enhancing transdermal drug delivery. It highlighted the advantages of 3D printing, such as creating personalized and cost-effective medical devices, and discussed various MN types, including hollow, solid, coated, dissolving, and swelling MNs. The review emphasized the potential of 3D printing to overcome traditional manufacturing limitations and addressed challenges in commercialization, such as material selection and regulatory issues. The document also explored different 3D printing methods, including FDM, SLA, DLP, and LCD, each offering unique benefits and challenges. Despite the promise of MNs, further research was needed to optimize 3D printing technologies and ensure safe and effective MN devices.
