technical note: the use of 3d printing in dental anthropology collections
Technology is becoming more economical and faster, and now it is possible to build models with high resolution and precision.
Due to the limitations of technology, 3D printing in biological anthropology is mostly limited to museum display and forensic reconstruction.
In this study, we compared the accuracy of different 3D printers to determine whether RP can be used effectively to reproduce the anthropology Dental Collection, which may replace the original material that is often fragile and irreplaceable
Methods: specimen collection of our digital yandumu native Australian dental castings used
Optical scanning systems and copying them using four different 3D printing techniques: stereo printing;
Simulation of molten deposition; binder-jetting; and material-jetting.
We used the color map generated by the 3D metric Deviation analysis to compare the deviation between the original 3D surface model and the 3D print scan.
Results: The 3D printing model reproduces the details and discrete morphology of the scanned dental castings.
The results of the metric Deviation analysis show that all 3D printing models are accurate and there are only a few small areas with high deviations. The material-
It is found that the performance of jet and stereo printing printers is better than that of the other two printing machines.
Conclusion: at present, the quality of commercial 3D printers has reached a good level of accuracy and detail reproduction.
However, the cost and printing time limit its application in producing a large number of samples for most anthropology studies.
Nevertheless, RP offers a viable option to preserve fragile bones and dental materials with digital constraints in the ancient anthropology collection.
