  • Validation studies compared the performance of RP-fabricated devices with traditionally made ones.

    • Main Results:

    • Rapid prototyping successfully produced custom devices with sub-millimeter precision.
    • Device channels with minimum diameters of 0.4 or 0.6mm were achievable depending on fabrication orientation.
    • Validation studies showed no significant difference in performance between RP-fabricated and traditional devices.

    Conclusions:

    • Rapid prototyping, particularly fused deposition modeling, is a valuable and accurate method for fabricating custom devices for neuroscience research.
    • The ability to rapidly iterate designs with low turnaround time enhances experimental flexibility.
    • Computer-aided design combined with rapid prototyping offers an excellent alternative for developing specialized neuroscience tools.
