Accuracy Evaluation of 3D Printed Casts by Different Printing Technologies
Additive manufacturing (AM) is a rapidly evolving technology already used in various industries, especially the dental industry. Various 3D printers with different manufacturing technologies can be used to fabricate physical casts from 3D virtual casts obtained from digital scanners. The advantages of 3D-printed casts include being lightweight, having minimal fracture risk, having high abrasion resistance, and having the ability to be fabricated in multiples. But shrinkage is inevitable during the 3D printing and post-curing processes. The following article reviews evidence-based scientific papers regarding the accuracy of 3D printing.
