Development of Cranium 3Dimension-puzzle products using 3D printing

Abstract
Anatomy is one of the most important and basic courses in health and medical education. Anatomical education used cadavers for its education media. Cadaver access is limited due to high prices and a limited donor. This triggered the development of anatomical education media, one of them is the use of 3-dimensional (3D) anatomical models. Additive manufacturing (AM), known as 3D printing, has developed rapidly over the last two decades and is used to produce physical models or prototypes. This research aimed to develop a 3D Cranium-puzzle product based on DICOM (digital imaging and communications in medicine) data processing. The data were converted into 3D using Fused Deposition Modeling (FDM) method. Data were obtained from the Department of Radiology, consisting of cranium data in the DICOM file. Cranium data in the DICOM file were converted into a 3D model and saved into an STL file. After getting the desired result, the threshold value was altered to determine the effect of the threshold value on the surface structure details. Anatomists validated the boundaries between bones until it meets the requirements according to the boundaries in the anatomical atlas. Finally, the 3D puzzle was printed using a 3D printer machine.
