Background and Objective: The 3D printing could be applicable in many fields. In this study, 3D models were constructed and printed according to size and shape of acrylic phantom. This study aimed to test the accuracy of 3D modeling for 3D printing.

Methods: The acrylic phantom was scanned by CT equipment storing data in a DICOM image format. Then the 3D model was created for 3D printing. Evaluate the results from the 3D model printed against the acrylic phantom, by assessing shape and size with sighting and measuring the width, length and height of each layer, and compare the differences by percent error.

Results: When visual assessment was performed, the 3D model and acrylic phantom, had  the same size and shape. And the width, length, and height of each layer had a percent error less than 2 percent.

Conclusion: In this study, to create and print 3D models had a size and shape expectation of less than 2 percent, error.
