3D-Printed On-Demand Drugs

A pharmaceutical scientist at the University of Sussex has published a guide to 3D and 4D printing technology in the biomedical and pharmaceutical arenas. Dr Mohammed Maniruzzaman, a lecturer in Pharmaceutics and Drug Delivery, edited 3D and 4D Printing in Biomedical Applications: Process Engineering and Additive Manufacturing’. He also authored sections of the book, alongside an international panel of academic scholars and industry experts. The book, written for pharmaceutical chemists, medicinal chemists, biotechnologists and pharma engineers, covers the key aspects of the printing of medical and pharmaceutical products and the challenges and advances associated with their development. It explores the process optimization, innovation process, engineering and technology behind printed medicine and provides information on biomedical developments such as shape memory polymers, 4D bio-fabrications and bone printing.

There are numerous potential applications of this emerging technology. In the future we predict doctors would be able to send a 3D prescription to a Pharmacy, via e-mail or a shared server, and the Pharmacists would then be able to print the required dosage via a 3D printer placed right at the dispensing counter- at the point of need, eliminating the need for paper-based prescriptions. Similarly, we are not far off from when patients would be able to print their own medication on demand by using their small printing unit right at the kitchen or bedside”, explains Dr Maniruzzaman.

Another example can be that a 3D printer or bio-printer placed right by the operation bed in the operation theatre can print the medical implants required for that patient lying on the bed just right at the point of care. The dimensions and geometry of the implants can be tailored specifically for that patient saving both time and cost for manufacturing. Above all, this would enhance the patient compliance significantly,” he adds.

3D printing has appeared as one of the most promising additive manufacturing techniques across many industries, now including the medical and pharmaceutical arenas. 4D printing is an emerging technology that, simply put, refers to a printed object that transforms over time. It is envisaged this technology will revolutionize biomedical developments.
