Craniofacial 3D Printing Workflow

The printing procedure has been thoroughly described in our previous study [15 (link)]. Briefly, the Mimics 3D image reconstruction software (Materialise, Leuven, Belgium) was used to process the data obtained from CT, MRI, and CTA scans to create a 3D reconstruction of the craniofacial strutures. The reconstruction was then transformed into a STL file. Objet350 Connex3 printer (Stratasys, Rehovot, Israel) was used in this study. Then, the STL files were loaded onto the printer, and parameters such as texture, color, and transparency were set using the Objet Studio software (Ver. 9.2.11.6817). Printing materials included Support Fullcure 705, VeroWhitePlus Fullcure 835, Veroclear Fullcure 810, Objet RGD836 Vero Yellow, Objet RGD851 Vero Magenta, and Objet RGD843 VeroCyan. The printer sprayed the materials onto the build tray, and every layer of materials was cured by UV light. After printing, the model was visually cross-checked with radiological scans.
