Impression tridimensionnelle. Un article de Wikipédia, l'encyclopédie libre. L'impression 3D ou impression tridimensionnelle sont les termes courants utilisés pour parler des procédés de fabrication additive. Initialement, en raison de leurs défauts originels, ces procédés ont été développés pour le prototypage rapide, mais maintenant ils sont de plus en plus utilisés pour la fabrication de pièces fonctionnelles. Bien que d'autres existent, voici quelques technologies qui coexistent : le FDM (Fuse Deposition Modeling : modelage par dépôt de matière en fusion), la SLA (Stéréolithographie : une lumière UV solidifie une couche de plastique liquide) et le frittage sélectif par laser (un laser agglomère une couche de poudre). L'impression tri-dimensionnelle permet de produire un objet réel : un opérateur dessine l'objet sur un écran en utilisant un outil de Conception assistée par ordinateur (CAO).

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.

Impression 3D internet. EOIR Technology. Case Study EOIR Technology was contracted to create a camera and mount for gun sights on M1 Abrams tanks and Bradley fghting vehicles for the Mississippi National Guard. EOIR’s subcontractor’s designs for the mount failed performance tests. EOIR found itself up against a tight budget and contract deadline with no deliverable solution. Using Solid Edge® CAD software and a Dimension 3D Printer, EOIR was able to quickly evaluate models of alternative designs. Sturdy ABS parts generated by Dimension proved tough enough to test directly on the armored vehicles without having to go through a costly, time-consuming process of machining them in aircraft-grade aluminum.
The Dimension Solution Functional models built with ABS plastic from the Dimension 3D Printer proved so tough that EOIR manufactured the fnal mounts on the 3D printer itself. What is 3D Printing? - Digital to Physical Through Additive Manufacturing. Working in 3D is fantastic fun. It's challenging, frightfully complex, and allows for almost boundless creative expression. However, compared to “real world” three dimensional art forms like woodworking, sculpture, ceramics, or textiles, 3D modeling is sorely lacking in one regard—the models have no real element of physical tangibility.
You can view the artwork on a screen or even make a high quality 2D print of a great render, but unlike a marble sculpture or a ceramic pot, you cannot reach out and touch it. You can't turn it in your hands, or run your fingers over its surface texture, feel the subtleties of its contours or its weight. For an artistic medium so reliant on form, it's a shame that a digital model must ultimately be reduced to a two dimensional image. Right? Not exactly. Here are some frequently asked questions about 3D Printing: How does 3D printing work?
