In this study, we tested the function of a replica of the over 500-year-old original of the
famous Franconian Imperial Knight Götz von Berlichingen’s first “iron hand”, which we
reconstructed by computer-aided design (CAD) and recently printed using a multi-material
3D printer. In different everyday tasks, the artificial hand prosthesis proved to be remarkably
helpful. Thus, the hand could hold a wine glass, some grapes, or a smartphone. With a
suitable pencil, even writing was possible without any problem. Although for all these
functions the healthy other hand was necessary to assist at the beginning, the artificial hand
is an astonishing mechanical aid with many possibilities. Therefore, in certain cases, the
non-invasive approach of a passive mechanical hand replacement, which is an individual,
quick and cheap solution due to modern 3D printing, may always be worth considering
also for today’s requirements.
Wir haben die erste „Eiserne Hand“ des Götz von Berlichingen mit 3D-Computer-Aided Design rekonstruiert und über einen Multimaterial-3D-Drucker ausgedruckt. Dabei ließ sich feststellen, dass die 500 Jahre alte Technik keinesfalls veraltet ist: Das Innenleben der „Eisernen Hand“ ist ausgefeilter als bisher angenommen. Sie könnte sogar spannende Impulse für die Entwicklung neuer künstlicher Handprothesen liefern.
