They could also be useful for patient education and preoperative planning for surgeons. Recently, scientists are using a combination of magnetic resonance imaging and ultrasound together with 3D printing technology to help doctors prepare for fetal surgeries. The process of manufacturing new tools can be lengthy and expensive. Even when created in-house or outsourced.
In critical situations, the long delivery time can literally be life threatening. The ability to visualize and explore complex anatomy as a real three-dimensional object allows medical professionals to afford decision-making support that was not available before. In a clinical setting, 3D printed models provide an opportunity to increase understanding of anatomical and pathological structures. The models serve as practical tools for testing the placement of implants and other medical devices, and for predicting surgical activities.
Advances, such as multicolor and multi-material printing, can also help to better simulate the surgical environment for pre-surgical planning and intraoperative reference. These models offer a dynamic complement to on-screen displays to build trust in healthcare decisions. As medical 3D printing technologies and materials continue to improve, they will pave the way for personalized care and high-impact medical applications. Recent advances in 3D printing in the healthcare sector have made it possible to manufacture lighter, stronger and safer products, reduce delivery times and reduce costs.
Since SLS printing does not require specific support structures, it is ideal for complex geometries, such as interior elements, crevices, thin walls and negative elements. The resulting orthosis, tailor-made and 3D printed, provided Nik with support, comfort and correction precisely where he needed it, helping Nik to finally take his first steps independently. While 3D printing has been used in healthcare for more than a decade to manufacture titanium and stainless steel implants, something called PEEK plastic will allow the technology to be used in more laboratories and clinics around the world. Initiatives such as e-NABLE allow entire communities around the world to learn about 3D printed prostheses.
With Draft Resin, Formlabs' SLA printers are also the fastest options for printing large prototypes in 3D, up to 10 times faster than with FDM. Elsewhere, MIT researchers have also identified 3D printing as an optimal means of producing more comfortable prosthetic cavities. In addition to providing a simple and accurate workflow for exporting models to 3D printers, the Simpleware software is also used to prepare models for future CAD design work, for example, for medical device manufacturers who carry out implant analysis and iterative design. Jonathan Morris, co-director of the Anatomical Modeling Laboratory and neuroradiologist at the Mayo Clinic, shares the history of 3D printing in medicine and examines real case studies of how radiologists have successfully introduced 3D printing capabilities and programs in hospitals.
Finally, the surfaces are exported to the 3D printer, usually as STL files for interpretation by the printer software, which adds support material and calculates and executes the printer head routes necessary to superimpose material and reproduce the computer model as a physical object. Melissa Powell, director of operations at Genesis HealthCare, describes the impact that 3D printing and additive manufacturing have had on medical device manufacturing in recent decades. FDM technology is the most used form of 3D printing among consumers, driven by the advent of 3D printers for amateurs. This method uses 3D scanning techniques such as magnetic resonance imaging, X-rays, computed tomography or 3D ultrasound to produce a volumetric image of the anatomy.
More than 90 percent of the top 50 medical device companies use 3D printing to create accurate prototypes of medical devices, templates and accessories to simplify testing, and they also directly 3D print medical devices. In addition to the ability to manufacture complex and customized parts, 3D printing in the healthcare sector is best suited for low-volume production, which means that costs will be reduced and efficiency will increase. .
