Michel Daronat is running a Z Corp Z-450 Color 3D Printer with improved, patented surface
post-finishing at ENSAM. The material is said to be
colorfast to 20 years.

De Dali aux nombres à 16 dimensions, un parcours éclairé par les mathématiques et illustré par les premières hypersculptures vous révèlera des clefs de mythes anciens (genèse, cabale, alchimie, apocalypse) et de théories scientifiques actuelles (géométrie non commutative, théorie des cordes, physique digitale, systèmes complexes). De passionnantes questions philosophiques, métaphysiques et scientifiques sont abordées par le langage de l’art visuel, plastique, dynamique et interactif.
La CAO s’est imposée à l’ENSAM à partie de l’année 1985 et sa première utilisation a été, bien sûr, une application industrielle. A partir de 1990 nous l’avons utilisée pour des reconstructions virtuelles (L’église abbatiale Cluny III par exemple). A ce jour la CAO est couplée au prototypage rapide pour la réalisation d’objets et à l’immersion virtuelle.Gas mask for Army from anatomical survey database.
In the last 20 years, mathematical objects have been represented, visualized and animated in very effective ways. Computer graphics turned out to be a powerful tool to improve understanding of Geometry of curves and surfaces and to attract people to Mathematics. Physical modeling of geometric shapes can be seen as a natural extension of virtual modeling: material models enhance our spatial perception of those objects by adding the tactile experience to the visual one. Moreover, in several occasions visual and material representations of mathematical objects played a central role in research development. In parallel with an overview of some famous models since the times of Galileo Galilei until today, I will show some models realized by means of several techniques and materials: plaster, wires, paper, metal and 3D printing, a technique used in manufacturing field to realize, through a layer-by-layer constructive method, accurate physical prototypes from 3D computer-generated models. 3D printing is probably the most powerful tool to produce very precise models of surfaces. In order to do that, one has to represent surfaces as solid bodies and this can be done in a natural way by constructing a thin solid shell around them. Such operation can be done by means of some standard differential geometry as long as the original surface is regular and injectively immersed in 3-space, while it requires some deeper work if it has self-intersections or singularities.Sr. FRANZONI exhibited phases of Thomas Banchoff's Moebius <-> Klein metamorphosis, rendered in 3D printing at the INTERSCULPT 2007/ENSAM venue.

"A platonic Tao"
I am not a mathematician, but a dreamer touched by the beauty of the mathematic volumes.
In the past, I illustrated some fictional landscapes in two dimensions — wide spaces into
which spheres made of two elements in search of an equality ratio were floating.
Few years ago, I put this concept in volume (which looks like a Tao representation):
two identical pieces, which look like a sphere, once put together.
Later on, looking for better understanding, I took on the quadrature density of the
platonic polyhedrons and their growing complexity.
But, besides the words, I am fascinated by their simple beauty.
I count on these volumes to give us an idea of their essence.

From traditional craftsmanship I went over the last two years to the computer as my “main workspace”,computer-video-animation, sculpting. I was strangely attracted to the beautiful renderings with Chaoscope of 3d strange attractors and fractals.Software: Chaoscope (Author: Nicolas Desprez)
When I read on the forum it wouldn't be possible to make them as real life forms I got enormously triggered. So after a lot of exercising with an experimental version of Chaoscope it was possible to make the right pointcloud data. By reverse engineering I could make almost perfect meshes from he pointcloud.
After that I could make solids out of it and repair the .stl files so they could be printed in polyamide and alumide (sls) and wit a 3dprinter in raisin for bronscasting.

From the soft-edged apple peels to the bird of paradise and leaves, from the hard-edged durians to desert cactus and coccothrinax, all can be formulated entirely by a 3-equations foundation. That is, one equation for each axis (x, y, z). The software auto computes the coordinates for each of the x, y and z axes as well as a varying real-time driven surface color and lighting parameters. Beyond asteroids, cardioid, deltoids, ellipsoids, lemniscate of Bernoulli or Gernoro, equations can be shaped to generate nature-like plants, birds and bees, marine creatures and 3D objects. Beyond the conceivable Nautilidaes and turritellidaes, equations can be used to formulate Balinese face masks, kimono and obi belts. These generated 3D structures can be animated and morphed automatically, and it can be Web-enabled.
When creating surfaces for the same object, equations are preferred over 3D modeling as it is extremely scalable and it is implemented with lean computational resources in hardware, software and manware, in fact, it is the minimum. This economy of expression is also the most flexible in real-time driven continuous facade changing for 3D geometry. It is an ecological purification of mathematically generated bit streams. This paper presents the results of an array of 3D structures formulated by equations.

The paper will explore recent research that attempts to exploit the sculptural potential of rapid prototyping in extending Donald Judd's concept Specific Objects. This has been achieved through a combination of deflected geometry, concentric deviance, and transparent structures. Consideration will also be given to the role of basic mathematical phenomena as an aesthetic tool that underpins the extension of singular forms with both variation and unity.Anish Kapoor -- Liverpool installation
Mes sculptures ou gravures sont simples - c'est ce que j'aime. L'utilisation des mathématiques permet de créer des formes simples. Comment définir la simplicité: Le grand spécialiste de la simplicité au MIT, John MAEDA, déclare: "Simplicity and complexity need each other." C'est à dire: Cette entité exige l’existence de son contraire. J'ai défini la simplicité comme l'inverse de la complexité ,ce qui donne:M VITKINE presents us with a contradiction -- I don't think there is a resolution.sim = 1/com ou ksim = 1000/comComment chiffrer la complexité:Compter le nombre d'éléments de l'œuvre : Symbole com.Comment définir un élément:
C'est une ligne ou une surface plane ou gauche sans discontinuité.
(Un volume est défini par la surface qui l'entoure)Quelques exemples: Sphère com=1 ksim = 1000 Hémisphère com=2 ksim = 500 Cube com=6 ksim = 167_________
Tout cela peut être contesté:
Si nous voyons la surface de la sphère comme composée d'une infinité de surfaces élémentaires, nous obtenons:com = infini ksim = 0---------------
Que pensez-vous de tout cela ?
Projet ASTRALE (Art Science Technologie Recherche en Amérique Latine et Europe) Réseau de collaborations scientifiques et culturelle France Amérique Latine avec pour thèmes principaux :ASTRALE -- Europe-Latin America collaboration
- Établir des relations de collaboration scientifiques et éducatives autour de projet concernant le patrimoine, en particulier, entre les mondes européen et latino-américain . Les domaines d'études envisagés concernent les sciences liées aux couleurs des matériaux, et les sciences du patrimoine, (chimie/physique, optique, restauration, histoire de l'art, archéologie, informatique et multimédia).
- Développer des outils 3D pour la valorisation du patrimoine (musées, collections publiques ou privées...).
Avec deux axes principaux :1- Le «musée virtuel 3D» ou les «expositions virtuelles 3D» permettant de réunir dans un même espace virtuels des oeuvres numérisées de provenance diverses (réserves de musées, collections particulières ...).
2- La simulation physico-chimique des matériaux constituant une oeuvre, par l'utilisation d'un moteur de rendu spectral basé sur les caractéristiques physico-chimiques des matériaux.- Se baser principalement sur des outils libres et open source.
