目标。确定四种市售增材制造系统的生产公差。方法。通过对 ISO_12836;2012 的附录 A 和 B 进行逆向工程，获得了两个与牙科相关的几何图形。对象 A 指定镶嵌形状对象的测量，B 指定多单元样本的测量，以模拟四单元桥梁模型。将对象分为 x、y 和 z 测量，对象 A 分为总共 16 个参数，对象 B 测试 12 个参数。这些物体是由四种不同的增材制造系统中的专业人员进行数字化设计和制造的；每个系统对每个对象产生 10 个样本。结果。对于对象 A，三个制造商给出的精度为
Objectives. To determine the production tolerance of four commercially available additive manufacturing systems.Methods. By reverse engineering annex A and B from the ISO_12836;2012, two geometrical figures relevant to dentistry was obtained. Object A specifies the measurement of an inlay shaped object and B a multi-unit specimen to simulate a four-unit bridge model. The objects were divided into x, y and z measurements, object A was divided into a total of 16 parameters and object B was tested for 12 parameters. The objects were designed digitally and manufactured by professionals in four different additive manufacturing systems; each system produced 10 samples of each objects.Results. For object A, three manufacturers presented an accuracy of
