4D printing, an evolution of 3D printing, introduces the dimension of time, enabling objects to change shape in response to external stimuli like temperature, light, or pH. In the healthcare sector, this technology is revolutionizing personalized treatment by producing medical devices that adapt to individual patient needs. For instance, 4D-printed orthopedic implants can conform to a patient's unique bone structure, promoting better integration and healing. This adaptability not only enhances the effectiveness of treatments but also improves patient comfort by reducing the need for multiple surgeries or adjustments. biomedical-engineering-online.biomedcentral.com
The potential applications of 4D printing in healthcare are vast. Researchers are developing smart drug delivery systems that release medication in response to specific physiological conditions, ensuring precise dosing and minimizing side effects. Additionally, 4D-printed scaffolds are being designed to support tissue regeneration, dynamically adjusting to the body's healing process. These innovations signify a shift towards more personalized and effective medical solutions, paving the way for treatments tailored to the unique needs of each patient. pmc.ncbi.nlm.nih.gov
