NCT07798739

Brief Summary

This study aimed to compare 3D-printed bone models produced using different infill densities and resin colors in terms of weight, anatomical accuracy, level of detail, texture quality, and similarity to real anatomical bone, and to determine the effects of infill density and resin color on perceived anatomical realism.

Outcome Measures

Primary Outcomes (1)

  • Visual Analog Scale

    The scale is 10 cm. A value of 0 indicates that the model is not similar to the real thing, while a value of 10 indicates that it is identical to the original model.

    once

Study Arms (1)

single group

Participants were asked to examine the structures of real bone models and 3D models printed in different colors in a laboratory setting, and to compare and evaluate the 3D models printed in different colors with the originals. The evaluation was done using a Visual Analog Scale (VAS) consisting of 4 questions about the weight, anatomical accuracy, level of detail, and texture quality of the model. Participants were asked to mark their results on a 10 cm straight line. A VAS score of 0 indicated that the model did not resemble real bone, while a score of 10 indicated that it was identical to the original model.
