A Hybrid Dental Model Concept Utilizing Fused Deposition Modeling and Digital Light Processing 3D Printing

Abstract

Currently, 3D printers, especially digital light processing (DLP) printers, are widely used in clinical dentistry. However, due to the shrinkage property of resin, their accuracy is not optimal for full-arch dental model printing. To overcome these limitations, fused deposition modeling (FDM) with filament that undergoes minimum shrinkage was introduced. Accordingly, a combination of FDM printing with the specific tooth die output of DLP printing for the full-arch dental model is proposed in the present report.
