3D printing, also known as additive manufacturing, has evolved far beyond its initial applications. This transformative technology builds three-dimensional objects layer by layer from a digital model. Initially recognized for its ability to produce prototypes and intricate structures, 3D printing is now asserting its dominance in healthcare. In this article, Alcimed explores the multifaceted impact of 3D printing on innovation in drug discovery, personalized medicine and the optimisation of pharmaceutical research.
The ability of 3D printing to rapidly produce prototypes is changing the landscape of drug development. Simple designs can be printed in a matter of hours, while more complex structures can be printed in a day or two. This rapid prototyping enables faster design iterations, allowing researchers to quickly test and refine their hypotheses.
One of the key benefits of 3D printing is the ability to create patient-specific devices and personalized dosage forms. This customization is particularly important in the context of drug development, where individual responses to drugs can vary widely. 3D printing makes it possible to create personalized drug delivery systems and formulations tailored to a patient’s individual needs, which can be beneficial in the design and conduct of clinical trials. FabRx exemplifies this with their Printlets® technology, which allows for the creation of customized drug dosages tailored to individual patient needs.
The wide range of materials available for 3D printing facilitates experimentation with substances that closely resemble those used in actual manufacturing processes. This innovation in materials expands the possibilities for drug testing, allowing researchers to simulate real-world conditions more accurately. This includes the use of various technologies, for example powder-based and extrusion-based systems, to create advanced drug delivery mechanisms and improve bioavailability of drugs.
One of the most exciting advances is in the field of bioprinting. Unlike traditional 3D printing, bioprinting uses living cells to create tissues and even organs. This breakthrough has huge implications for regenerative medicine and personalized healthcare, promising solutions for organ transplantation and tissue engineering.
In the emerging field of bioprinting, companies such as Carcinotech are pushing the boundaries of innovation. Based on the concept of replicating the tumor microenvironment (TME), Carcinotech’s Carcino3D technology uses 3D bioprinting to create living tumor models. This approach aims to provide a more accurate representation of real tumors, enabling improved drug testing and the development of personalized medicine.
Traditional immunological models often take months to develop and are not always compatible with automated systems. 3D-printed models, on the other hand, offer a solution to these challenges. In their EXISTM platform, Prellis Biologics’ uses donor blood cells and machine learning to develop bio-printed lymph node organoids (LNOTM) to help discover antibodies with high therapeutic potential. Advancements of this type have great potential to revolutionize drug screening, making it more cost-effective and predictive of real-world outcomes.
Another leading company, Poietis, specializes in creating complex tissue models using laser-assisted bioprinting technology. By focusing on personalized medicine, Poietis develops patient-specific tissue models for drug testing and regenerative medicine, enhancing the accuracy of drug testing and personalized treatment development.
Beyond drug development, additive manufacturing (AM) is proving to be transformative in the medical device manufacturing sector. The integration of AM processes, such as 3D printing, addresses key challenges in speed, cost, and quality.
Speed is of the essence in medical device manufacturing, especially for patient-specific devices. The rapid production capabilities of additive manufacturing processes accelerate development, reduce dependence on external suppliers and improve overall efficiency in the medical device supply chain.
Cost considerations are paramount in the medical device industry. AM offers cost-saving benefits by minimising material waste, providing design flexibility and reducing reliance on expensive tooling and moulds. Bringing additive manufacturing in-house further helps to control costs and streamline production processes.
Maintaining strict quality standards is essential in the medical industry. Controlled and validated additive manufacturing processes, coupled with real-time monitoring technologies, ensure repeatability and reliability in the manufacturing process. This is particularly important for medical devices, where precision and consistency are non-negotiable.
