Additive manufacturing technology has benefited many sectors, and its use in forensic sciences has opened up a variety of new opportunities for analysing and exhibiting forensic materials. However, to perform analytical procedures on 3D printed bones and teeth in forensic odontology, the metric and morphological precision of the printed replicas must first be validated. To address this, the present study was undertaken using 12 extracted human teeth that were 3D printed using five different techniques. Manual measurements and a digital mesh comparison were used to evaluate the metric precision of all samples. The findings showed that the printed replicas were accurate to within 0.5 mm of the actual teeth. It was suggested that Digital Light Processing (DLP) prints be used for potential forensic odontology applications based on measurements, digital comparison, and ease of use.
增材制造技术已经造福了许多领域，其在法医学中的应用为分析和展示法医材料开辟了各种新的机会。然而，要在法医牙科学中对 3D 打印的骨骼和牙齿进行分析程序，首先必须验证打印复制品的度量和形态精度。为了解决这个问题，本研究使用 12 个人工提取的牙齿，使用五种不同的技术进行 3D 打印。手动测量和数字网格比较用于评估所有样本的度量精度。研究结果表明，打印复制品的精度在实际牙齿的 0.5 毫米以内。基于测量、数字比较和易用性，建议使用数字光处理 (DLP) 打印用于潜在的法医牙科学应用。
