UI researchers developing 3D printer, 'bio-ink' to create human organs
Experts agree that rising Chinese labor costs and improving U.S. technology will gradually cause significant manufacturing activity to return to the United States. When it does, a new interdisciplinary manufacturing venture called the Advanced Manufacturing Technology (AMTech) group at the University of Iowa College of Engineering’s Center for Computer Aided Design (CCAD) will likely help lead the charge. AMTech was formed to design, create, and test—both virtually and physically—a wide variety of electromechanical and biomedical components, systems and processes. Currently, the group is working on projects ranging from printed circuit boards for automobiles and aircraft to replacement parts for damaged and failing human organs and tissue, says Tim Marler, AMTech co-director. “Electromechanical systems are one of two current branches of the AMTech group,” he says. In fact, the multi-arm bio printer being used in the lab is unique. Related:  L'impression 3D dans la vie de tous les joursActualité : L'imprimante 3D.

OEDK - Rice University - 3D Printer 3-D Printer The 3-D printer is a rapid prototyping machine for making plastic prototypes from CAD models. The item is printed using Acrylonitrile Butadiene Styrene (ABS) plastic and a support material, allowing for complicated 3-D shapes. It can easily and fairly rapidly create 3-D models from computer files created using SolidWorks®, IronCAD®, or virtually any other 3-D rendering suite. The resolution of the machine is 0.02 inches in the x, y, and z directions. Before you use the 3-D printer, there are several things to consider. Format The file you need in order to operate the 3-D printer is an .stl file. Budget To start with, there is a $5.00 processing charge for use of the plastic base and sodium hydroxide bath. Scheduling and Patience Although you do not have to pay for time on the machine, printing parts can take hours. You can expect a minimum of one day processing time prior to the commencement of printing. Necessity

3D Print Lab - School of Engineering Education 3D Printer Information The Ideas to Innovation Laboratory has two Objet Eden350 and one Objet Eden350V 3D Printers. These printers are based on Objet's PolyJet photopolymer jetting technology that builds horizontal layers of 16-microns (0.0006 in) of model resin and support material, which is cured using ultraviolet light. Both the Eden350 and Eden350V print in High Quality mode, with X and Y resolutions of up to 600 dpi, allowing rapid production of models with very fine details. Printing Costs The cost of printing is based upon the amount of material used by weight (includes model resin and support material). Model Materials The I2I Lab stocks the following model resins and support material: Additional model resins can be ordered upon request from Objet's Website. Model Dimensions The Eden350 and Eden350V printers have a tray size of 350 (X) x 350 (Y) x 200 (Z) mm (13.8 x 13.8 x 7.9 in) which offers the flexibility to produce a single large model or multiple smaller models in one build.

L’imprimante 3D, ce gadget qui change le monde Imprimante 3D de la marque Makerbot Le salon des techniques de l'information et de la communication (Cebit) se déroule cette semaine à Hanovre en mettant à l'honneur l'économie du partage. On entend beaucoup parler de l'émergence de cette économie, mais ce partage croissant de connaissances, de ressources, de contacts, d'échanges ou d'emprunt d'objets peut-il changer le monde ? Quels sont les nouveaux espaces d'innovation ? Sont-ils portés par l'ambition de bâtir un monde plus viable ? Bienvenue dans l'industrie du bricolage Dans Makers, la nouvelle révolution industrielle, l'américain Chris Anderson estime que l'impression 3D et la multiplication des possibilités données à chacun de bidouiller par lui-même et en réseau, de manière libre et ouverte, dessinent les contours d'un nouveau modèle économique de fabrication. Oui mais voilà : quand on y regarde de plus près, il est important de distinguer les vecteurs de cette révolution annoncée. Une impression pas nette En plastique...

A 3D Printer Debuts at Williams | Williams College “3D printing is going to be pervasive in the future, and I want to be able to say I was involved from the first,” says sophomore Christine M. Cunningham ’15, a likely computer science major. As one of the team of 10 students that worked with design engineer and model maker Michael Taylor and computer science professor Morgan McGuire to build a 3D printer during Winter Study, Cunningham has reason to be proud. Christine Cunningham ’15, Morgan McGuire, Michael Taylor, and Sam Donow ’16. 3D printing, also known as desktop fabrication, is being used to produce components in a variety of industries from the medical industry to toy manufacturers. As the head moves back and forth along the square glass plate, the first layer of blue plastic is laid down in the shape of an airplane, line by line, slowly moving back and forth, up and down, and around the glass. The students built this printer from directions they cobbled together through open-source materials.

3D Rapid Prototyping § Printing a 3D model directly from a computer file has become a popular process for model-making and prototyping at the GSD. Generally, a "watertight" mesh digital model is necessary for any printing operation - no open edges or seams. 3D printed models are still subject to the forces of gravity and self-weight, so although a 3D printer can print just about any closed geometric entity, that is no guarantee the printed part will be able to stand on its own or be handled. Users are advised to consider this when creating their models for 3D printing and when selecting which printer technology to use. The GSD has three different printer technologies available: ZCorp Printers The Zcorp 3D Printer was the first rapid prototyping tool brought to the design school, and it remains the most widely used given the relative speed and consumable cost of the technology.

Descriptif des services d'impression 3D untitled Arduino est un modeste circuit imprimé de quelques centimètres carrés. Il permet à quiconque, sans grande compétence en informatique ou électronique, de fabriquer des appareils électroniques uniques. Quant aux Fablabs (fabrication laboratory), ils permettent de fabriquer "presque n’importe quoi". Ces deux innovations préfigure-t-elle un monde où les objets et les appareils seront fabriqués de manière unique et réparés plutôt que jetés ? Sont-elles la prémisse d’un monde où n’importe quel bricoleur pourra créer et répliquer un virus ou une arme chez lui ? Entretiens avec : - Jacques Falquet, biochimiste et concepteur de nombreuses applications sur Arduino, - Théo Reichel, informaticien et conseillé en informatique, concepteur de nombreuses applications sur Arduino et imprimantes 3D, - Jérôme Gleizes, économiste au laboratoire IDHE-CNRS de l'ENS de Cachan et codirecteur de publication de Ecorev Un dossier d’Adrien Zerbini

L'impression en 3D bientôt dans votre salon Le procédé devrait rapidement se démocratiser avec l'arrivée sur le marché d'imprimantes 3D très performantes à moins de 2000 dollars (1600 euros environ) d'ici à 2016, selon le cabinet Gartner. L'impression 3D a le vent en poupe. Elle est même présentée par certains comme la prochaine révolution industrielle. Grâce à cette technologie, il est possible de réaliser des objets en très petite série, voire à l'unité. Déjà utilisée dans le domaine de l'industrie pour faire des prototypes depuis plus de dix ans, l'impression 3D se diffuse plus largement pour gagner les PME et même le grand public. Le principe de l'impression 3D peut être comparé à celui de l'impression jet d'encre. L'impression 3D «va permettre de relocaliser» «L'impression 3D va rapidement être disponible dans des kiosques ou des boutiques, créant de nouvelles opportunités pour les détaillants et d'autres business», prédit Pete Basiliere, analyste chez Gartner. » Une arme à feu faite maison avec une imprimante 3D

Near term, the technology could lead to better systems for growing and studying cells, including stem cells, in the laboratory. Long-term, the goal is to be able to print biological tissues for regenerative medicine. For example, in the future, doctors may repair the damage caused by heart attack by replacing it with tissue that rolled off of a printer. Reported in the journal Advanced Materials, the biofabrication technology, called dynamic optical projection stereolithography (DOPsL), was developed in the laboratory of NanoEngineering Professor Shaochen Chen.
