Computer-aided design allows precise planning of patient-specific implants and can increase the planning accuracy of the surgical procedure through the use of additive manufacturing. The "ImplaNDT-Sim" project combines 3D-printed patient-specific implants made of medical grade PEEK with a skull made of synthetic bone material with realistic mechanical properties and artificial soft tissues to build a modular simulator for biomechanical evaluation and medical training. On the one hand, this will be used to investigate and evaluate the performance of the printed implants in impact tests. On the other hand, the quality of the additively manufactured implants will be examined non-destructively before and after the load tests by means of micro-computed tomography (µCT). The printing accuracy is analyzed with regard to geometric deviations between virtual planning and 3D-printed implants. In addition, the training simulator allows experienced surgeons as well as doctors in training to perform various surgical scenarios on the model using the real instruments. The experience gained increases patient safety and reduces surgery time and the risk of complications.
