Finite element simulations are a valid, FDA-acknowledged alternative to experimental tests, which are time-consuming, expensive, and labor-intensive. However, when applied to 3D-printed meta-biomaterials, state-of-the-art finite element modeling approaches are becoming increasingly complex, while their accuracy remains limited. A critical condition for accurate simulation results is the identification of correct modelling parameters. This study proposes a machine learning-based strategy for identifying model parameters, including material properties and model boundary conditions, to enable accurate simulations of macro-scale mechanical behavior. To achieve this goal, a physics-informed artificial neural network model (PIANN) was developed and trained using data generated through a fully automated finite element modeling workflow. Subsequently, the PIANN model was then tested using real experimental force-displacement data as its input. The experimental data from 3D-printed structures were used to predict the associated parameters for finite element modeling. Finally, the workflow was validated by qualitatively and quantitatively comparing simulation results to the experimental data. Based on these results, we concluded that the proposed workflow could identify model parameters such that the predictions of associated finite element simulations are in agreement with experimental observations. Furthermore, resulting finite element models were found to outperform state-of-the-art models in terms of both quantitative and qualitative accuracy.

However, there is a paucity of data on economic aspects of the manufacturing of 3D-printed orthoses (3DPOs). The aim of this study is to economically evaluate the manufacturing process of 3DPOs compared to conventional low-temperature thermoplastic orthoses (LTTOs) in a clinical setting. METHODS: A prospective cost minimisation analysis from a healthcare provider perspective was conducted including 17 wrist orthoses (8 3DPOs and 9 LTTOs). RESULTS: The mean cost per orthosis was significantly higher in 3DPOs (€ 46.54) than in LTTOs (€ 30.28). The main cost factors in 3DPOs were the labour (62.2%) and purchase cost (22.2%), while the material (69.4%) and labour cost (30.6%) were most important in LTTOs. CONCLUSIONS: The high initial investment might be a hurdle in the implementation of 3DPOs in hand rehabilitation, however, lower material cost and less waste is a benefit compared to LTTOs.
