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.
Various methods of Digital Manufacturing (DM) have been available for the manufacturing of physical architectural models for several years. This paper highlights the advantages of 3D printing for digital manufacturing of detailed architectural models. In particular, the representation of architectural details and textures is treated. Furthermore, two new methods are being developed in order to improve the conditions for the application of digital manufacturing of architectural models.
A variety of different additive manufacturing processes have been available for the last three decades. Some of these technologies are very energy-intensive, e.g. laser technology and the manufacture of metal powder. In many areas, the detailed investigation of the energy and material consumption of these new manufacturing methods is still in the beginning. This paper investigates energy and material consumption using 3D colour printing (3DP) as an example. The specific energy required for the layering can be determined from this. This then forms the basis for a comparison of the specific energy consumption with other generative (e.g. Fused Layer Modelling—FLM) and also conventional production processes (e.g. milling and grinding). Thus process selection is facilitated by introducing the specific energy for layering. In addition several variables, in which resource consumption can be reduced are also investigated and compared. For example the influence of the geometry or the positioning of the 3D-printed part in the design space on the consumption are investigated. But also the measuring of different batch sizes is compared. Using the results found, the use of 3D printing can initially be optimized so that less energy, resources and manufacturing time are required.
