FEATURES OF 3D PRINTING OF ORAL FILMS

Abstract

3D printing technology is revolutionizing the medical industry by offering personalized and efficient solutions for the production of medical devices, implants, and prostheses. This technology enables the creation of complex geometric shapes that were previously unachievable or impractical with traditional manufacturing methods, significantly enhancing the personalization of treatment while reducing both cost and production time. The development of new polymer materials is expanding the capabilities of this technology, improving the biocompatibility, mechanical properties, and biodegradability of materials. Techniques such as Stereolithography (SLA), Selective Laser Sintering (SLS), Digital Light Processing (DLP), Fused Deposition Modeling (FDM), and MultiJet Printing (MJP) are increasingly used to produce accurate medical prototypes. Despite the vast opportunities 3D printing technology offers for personalized treatment and medical device production, several critical challenges remain. Material safety is of paramount concern, as not all materials used are adequately tested for biocompatibility and compliance with medical standards. Ensuring high accuracy and quality in 3D printed products also presents significant challenges, particularly when scaling up production. Additionally, regulatory issues concerning the classification and certification of 3D-printed medical devices need more standardized and unified approaches. Another significant issue is the high cost associated with 3D printing technologies and materials, which can restrict their accessibility, especially in developing countries. However, ongoing software development and improvements in technological processes hold the potential to overcome these barriers, significantly expanding the role of 3D printing in healthcare.
