Recent developments in additive manufacturing methods enable to create individual prostheses, using scanned data or parametric models. Therefore, it is worth investigating the possibilities and limitations of such products. The requirements of prosthetic feet are difficult to comply with and differ in evaluation aspects such as rollover shape, energy return, load-bearing capability, etc. The available literature is sparse regarding the testing and FEA analysis of 3D-printed prosthetic feet. This paper presents simulation methods conducted on self-designed prosthetic foot concepts. One design was manufactured using Fused Deposition Modeling and ABS filament. The effect of the geometry and infill pattern on the energy return is discussed based on test results. The load-bearing capability of the initial design was improved due to its failure, and examined by more extensive simulations.
