Preoperative　models　manufactured　by　3D　printing　technology　are　widely　demanded　in　surgical　procedures.　Current　printing　methods　such　as　Polyjet,　color　jet　printing　(CJP)　and　fused　deposition　molding　(FDM)　are　either　too　expensive　or　of　poor　performance.　In　this　paper,　a　novel　solution　is　proposed.　Preoperative　models　are　first　divided　into　internal　part,　such　as　blood　vessel,　and　the　main　body.　The　former　is　printed　in　color　and　the　latter　is　transparent.　In　particular,　the　internal　part　is　printed　using　FDM.　A　housing　template　for　the　main　body　is　generated　by　digital　light　processing　(DLP)　based　on　the　preoperative　model.　After　integrating　the　template　and　inner　part,　transparent　elastomer　precursor　is　injected　and　cured　inside　the　template,　leading　to　the　formation　of　the　transparent　main　body.　For　demonstration,　a　liver　model　is　manufactured　using　the　proposed　scheme.　Compared　with　the　existing　methods,　our　strategy　could　manufacture　preoperative　models　at　both　high　quality　and　affordable　cost.　©　2022　Owner/Author.
