This machine is capable of printing parts and assemblies made of multiple model materials, all in a single build. The materials used to fabricate the ear prosthetic element were the TangoBlackPlus 18 G. Sansoni and F. Docchio Shore A85 for the area corresponding to the auricle surface, and the TangoBlackPlus Shore A27 for the areas at the borders of the ear. The ear was obtained in about one hour; the process is very cheap (the cost is in the order of 70 Euros). Fig. 20 shows the front and the back sides of the final prosthesis.

As a means to test the performance we selected the SSVEP, since this is a well understood phenomena and as it is one of the most popular neural sources in BCI applications. The analysis has revealed that both electrode types can replace the gel-based configuration, but at the expense of performance. The mean accuracy rate drops by 10 − 25% when using water-based electrodes and by 35 − 45% when using dry electrodes. The information transfer rate in the optimal case is one half for water-based and one third for dry electrodes, compared to gel-based ones.

Although this coincides with the results obtained in [41], as we did not used any advanced algorithm for SSVEP response estimation, these results were unexpected. To better understand these results we analyzed the impact of noise on the signal, and the signal quality in different electrodes. Spectral Content across Electrode Types and Positions. By comparing the raw signal and the power spectra obtained within different EEG channels we observed the following: 1. The noise component in the EEG signal, being environmental or physiological, can be observed for all setups.
