Fraunhofer Additive Manufacturing Alliance

Fraunhofer Additive Manufacturing Alliance

The Fraunhofer Additive Manufacturing Alliance has restructured the work begun by the Fraunhofer Rapid Prototyping Alliance and is continuing to develop it to the same high standard of quality. We benefit from the accumulated years of experience acquired by the thirteen member institutes and from the intensive transfer and sharing of expertise amongst them.


Pushing the Limits of 3D Color Printing: Error Diffusion with Translucent Materials

Accurate color reproduction is important in many applications of 3D printing, from design prototypes to 3D color copies or portraits. Although full color is available via other technologies, multi-jet printers have greater potential for graphical 3D printing, in terms of reproducing complex appearance properties. However, to date these printers cannot produce full color, and doing so poses substantial technical challenges, from the shear amount of data to the translucency of the available color materials. In this paper, we propose an error diffusion halftoning approach to achieve full color with multi-jet printers, which operates on multiple isosurfaces or layers within the object. We propose a novel traversal algorithm for voxel surfaces, which allows the transfer of existing error diffusion algorithms from 3D printing. The resulting prints show tremendous detail and realism.

A one-two-three win for young researchers

Energy-efficient heat exchangers and resource-efficient electron beam melting: in 2015, for the ninth time, the STUDENT DESIGN & ENGINEERING AWARD for Rapid Manufacturing offered creative minds the opportunity to take their innovative ideas from design to production. In light of current events, the central theme this year was "Energy".
All three winners are students from the member institutes of the Fraunhofer Additive Manufacturing Alliance - a network of 13 Fraunhofer institutes who carry out research in the field of additive manufacturing. The young scientists were able to convince the international jury with their design concepts for optimum energy use.
