Abstract
A photo-curable resin composition is suitable for the fabrication of 3D printed objects via digital light processing (DLP) or stereolithography (SLA). The photo-curable resin composition can provide 3D printed objects having lower volumetric shrinkage, high accuracy and favorable mechanical strength for dental application such as building models, implant templates, surgical guides, night guard/occlusal splints, dentures, clear aligners, and temporary restorations.
