Researchers Create Better Techniques for 3D Printing Surgical Models
Medical professionals and surgeons around the world have been greatly helped with the emergence and innovation of 3D printed models that not only help pinpoint a diagnosis, but also educate patients and their families regarding health issues (often regarding diseases like cancer and tumors that must be removed). Ultimately, these models can be used by surgeons to practice for delicate surgeries, and then also act as guides in the operating room.
Both US and German scientists have come together now to find improved methods of 3D printing such models and guides, publishing their findings in ‘From Improved Diagnostics to Presurgical Planning: High-Resolution Functionally Graded Multimaterial 3D Printing of Biomedical Tomographic Data Sets.’ While the authors point out how useful anatomical structures are in the medical field, they also explain why 3D printing medical models is currently rife with challenges:
3D printing of surgical models can be flawed due to reasons like thresholding, or error in digital structure that prevent files from printing and then require users to make additional changes later. The researchers see multimaterial 3D printers as a solution due to their ability to use more than one .stl file:
As a result, their study is centered around showing how functional bitmap-based workflows are helpful in fabricating biomedical data sets, permitting rapid creation of anatomical models without thresholding. The scientists also ‘bypassed’ more typical 3D printing workflows due to their potential for error, and worked with both MRI and CT data.
