Masked stereolithography 3D printing of a brain tissue from an MRI data set
Özet
3D printing technology holds tremendous promise for applications in the medical field, particularly in the cre
ation of anatomical models. The accuracy of 3D-printed anatomical models is of utmost importance, especially
for surgeons engaged in complex surgical planning. The goal of this study was to create an anatomically precise
model of brain tissue using data obtained from an MRI scan, with a resin-based Masked Stereolithography 3D
printer, and to assess the model’s potential uses. The process of creating an anatomical brain model with an SLA
3D printer was divided into six fundamental stages. The 3D printing process for this project necessitated 55.4 g of
resin, and the total printing time was 4 h and 56 min. Any liquid resin residues on the brain structure eliminated
through cleaning have been conducted using 99.6 % pure isopropyl alcohol. Following the printing phase, the
produced model underwent a curing process in a chamber illuminated with ultraviolet light at a wavelength of
405 nm to ensure complete solidification. Once solidification is completed, the dimensions of the brain are
measured with a micrometer and compared with those digitally generated from the MRI scan data. The results
showed that the overall dimensional error was less than 1 %.
