Figure 1

Illustration of the fabrication process for a conjoined twin model: (a) Fabrication of a soft tissue phantom (using the kidney-bladder group as an example). From left to right: computer aided design (CAD) model of the kidney-bladder group, shell mold of the kidney-bladder group produced by the FDM process, silica phantom of the kidney-bladder group cast by the shell mold. (b) Assembling the phantoms of the five organ groups. (c–e) Multiple positioning holes and columns are designed on the phantoms to ensure accurate positioning of the phantom assembly. (f) The organ assembly is placed inside a shell mold that simulates the body surface for further casting. The position accuracy. (g) Positioning hole is designed on the shell mold to ensure accurate positioning of the phantom assembly.
