A 3D printing technology can be used to deal with this drawbacks. A series of algorithms were developed to ensure that two adjacent bone fragments fabricated can be assembled successfully. In this study, we developed a bone reduction algorithm, and a mesh-overlapping detection and removal algorithm to ensure that two 3D-printed fragments are easily assembled and disassembled. In addition, we also developed a method to detect and extract fracture boundary from two adjacent fragments, and then apply a multi-color 3D printing technology to fabricate the assembled bone fragments. The advantage of the proposed method is that we can show the status of 3D-printed bone fragments before and after bone reduction, with fracture lines printed in different color.Keyphrases: bone reduction, fracture lines, mesh overlapping, multicolor 3d printing In: Wei Tian and Ferdinando Rodriguez Y Baena (editors).
