Philipp Urban, head of Fraunhofer IGD's Competence Center 3D Printing Technology, was invited by the 3MF consortium to present recently published work on a joint color and translucency representation at its meeting in New York City, June 27, 2019. The proposed representation can be encoded in the widely supported RGBA format and is particularly suited for 3D printing. The publication can be found here and Philipp’s slides here.
3MF is an industry consortium working to define a 3D printing format that will allow design applications to send full-fidelity 3D models to a mix of other applications, platforms, services and printers. The consortium’s goal is to provide a specification that eliminates the issues with currently available file formats, and allows companies to focus on innovation, rather than on basic interoperability issues.
Cuttlefish senior developer and research scientist with Fraunhofer IGD's Competence Center for 3D Printing Technology, Alan Brunton, was invited to present some of the scientific work behind Cuttlefish's unique ability to jointly reproduce both color and translucency at the inauguration day of the APPAMAT research group in St. Etienne, France on Tuesday, 11 June 2019. Inauguration day program. Slides of Alan's talk.
The APPAMAT research group includes researchers from many top French institutions, including CNRS, the University of St. Etienne, Aix Marseilles University, the French Color Center, among others.

The first metal prints created by Cuttlefish have arrived! This work is part of the Fraunhofer FutureAM project in collaboration with Fraunhofer ILT, where Cuttlefish adapts the laser parameters of the SLM process to the part geometry. We created a 3D version of our logo and added lattice structure to make it more interesting. Check out the photo here and in our gallery.
We are presenting Cuttlefish at formnext in Frankfurt am Main from November 13 to November 16. We will be presenting at both the Fraunhofer-Allianz Generative Fertigung stand at Messe Frankfurt (Hall 3.0 Stand E70) and the Stratasys stand (Hall 3.1 Stand G40), so drop by either one to learn more about how Cuttlefish can get the most out of your 3D printer.
Our highlight this year is the following anatomy model printed at a height of 47cm, which is the Leitexponat, or keynote exhibit, of the Fraunhofer-Allianz Generative Fertigung. The model is a composition of 28 sub-parts, each of them assigned a unique material, comprising over 425 megapixels of color texture data. For some of the sub-parts we use Cuttlefish's Surface Voxel Shader feature to manipulate the appearance, e.g. the transparency of the object. At 47cm, the print volume comprises 134 billion voxels. Click on the images below to have a closer look at the results, or stop by formnext to see her "in person".
The project produced true-to-scale and color-calibrated replicas of ancient artifacts through contact-free 3D digitization and 3D printing. They serve exhibition purposes at the original location Roseninsel. The originals are of high value and are therefore not allowed to be displayed for safety reasons. Also, the production of replicas by traditional print-making methods were not considered as suitable due to the risk of damaging the original surfaces.
The project was carried out in cooperation with the 3D Printing Department at Fraunhofer IGD to use the color printer driver Cuttlefish for reproducing the geometry, colors as well as fine color transitions of the original.

The features of 3D printing are significant for the movie industry. The US animation studio LAIKA, relies on using the cutting edge software and 3D printing hardware to make its films. A new collaboration with Fraunhofer and Stratasys now adds the ability to print thousands of precise colors and subtle gradients in plastic, achieving color accuracy unseen in the past.
(Portland/Darmstadt) Stop-motion animation has a unique appeal. When employing the technique, twenty-four frames equal one second of animation. Each frame must be meticulously set up with puppets and props incrementally altered in small movements. An entire movie is compiled from the individual motionless scenes, captured by a digital camera. LAIKA, the US-based animation studio, has produced three Oscar®-nominated animated films: The Boxtrolls (2014), ParaNorman (2012) and Coraline (2009). Their use of 3D printing in animation garnered them a Scientific and Engineering award from the Academy of Motion Picture Arts and Science. The studio’s fourth feature, Kubo and the Two Strings, will open in theaters this year.
In order to produce the puppets facial expressions, LAIKA designs, models, animates and paints the faces in the computer, then uses color 3D printers to produce tens of thousands of slightly different facial expressions. LAIKA pioneered this technique on it’s inaugural film Coraline and has continued to push the limits of 3D Printing technology on each subsequent film. On LAIKA’s fifth film they will be utilizing the most cutting edge color plastic printing hardware from Stratasys combined with the powerful universal print driver Cuttlefish from Fraunhofer IGD to help achieve accurate and repeatable color from face to face.
Cuttlefish makes it possible to work with many printing materials at the same time, to accurately replicate the geometry, colors and smooth color transitions of the original, and to simulate the printout on screen in advance. “Our first tests were fantastic”, says Academy Award winner and director of LAIKA’s rapid prototyping department, Brian McLean. “We have never seen such accurate and detailed color before in a plastic 3D print.”

Our paper, "Pusing the Limits of 3D Color Printing: Error Diffusion with Translucent Materials" has been accepted to ACM Transactions on Graphics (TOG), the top journal in computer graphics. See below for links to the preprint and the accompanying video.
Our technical report on using advanced error diffusion methods on surfaces is now available on arXiv.org. From a technical standpoint, we developed a traversal algorithm for voxel representations of surfaces, which allows us to use anisotropic 2D error diffusion filters from 2D halftoning. We transfer printer tonal values inside the object, extract multiple offset surfaces within the object and apply the same technique on them independently. This produces the prints you see in the gallery. For details, check out the paper. Also check out the video.
Fraunhofer IGD devoted a special edition of the Visual Computing Report - Video Podcast to us. It shows our current work in 3D Printing.
We were invited by Stratasys to present Cuttlefish at their booth.
