Glossary This is a list of common terms and abbreviations used in the RepRap community. Acrylonitrile Butadiene Styrene, a thermoplastic used as a 3D printer material. Often ABS is used as a short form, actually referring to filament made of ABS: 'Do you use ABS in your Mendel?' Be careful that sometimes filament sold as ABS is in fact mixed with other thermoplastic, thus altering its characteristics. The melting temperature is 220-230°C, but can be different if the manufacturer has mixed this with other thermoplastics. ABS is soluble in acetone and can be use to smooth the surface of the print-out. Bed The build plate of the 3D printer on which parts are actually made. Belt Toothed gear belt, usually fiber-reinforced to prevent stretching (ex: GT2). Biopolymer Biopolymer has different meanings and is classified by Enders. Bill of materials. Also said to be "Book of Materials" in some contexts. Computer Aided Design / Computer Aided Manufacturing. Computer Aided Engineering. Carriage Catalyst Copolymers
70+ Web Tools Organized For Bloom's Digital Taxonomy The number of web tools currently available to teachers, administrators, and students is downright absurd. You can’t swing an iPad without hitting a free web tool looking to revolutionize your classroom. Luckily, there are a few brave souls out in the world wide web attempting to organize the chaos a bit. We like to take our best shot here at Edudemic but also like to showcase some of the great organizing done by others. One of those fabulous organizers is Phillippa Cleaves ( @pipcleaves – worth following!) The web tools are all listed (and clickable!) NOTE: You can click on any of the web tools listed in the presentation to go to their respective website. Source of top image: Wikispaces
These New 3D Models Put the Smithsonian’s Most Renowned Items in Your Hands | At the Smithsonian The Wright Flyer, the legendary aircraft built by the Wright Brothers and sent skyward over Kitty Hawk in 1903, was acquired by the Smithsonian in 1948. Since then, it’s been on public display nearly continuously. Of course, visitors aren’t allowed to touch the plane, and educators teaching lessons on the Flyer have had to use models to give students the chance to handle it and see it from different positions. Engineers and historians have faced similar limitations, unable to climb inside to examine its inner machinery or take out a tape measure to assess its specs. Now, though, anyone with an internet connection can handle a virtual 3D version of the Flyer and print a replica at any scale. “For a while, we were able to create these incredible, high-resolution 3D models, but in terms of public access to the data, we were really limited,” says Rossi. “If you play any video game, you’re looking at a polygonal model, and that’s also what you’re looking at in the viewer,” Rossi says.
Solar System Scope How To Create Outstanding Modern Infographics In this tutorial you will learn that data doesn't have to be boring, it can be beautiful! Learn how to use various graph tools, illustration techniques and typography to make an accurate and inspiring infographic in Adobe Illustrator. Start by using the Rectangle Tool (M) to draw a shape. The entire design is based on a grid of four columns. Condense the shape so it fits within the left-most guide and centre guide. Move the shape over to the right and add another guide to the centre here. Using the Rectangle Tool (M) draw a thin white box on the centre line that will be the width of the gap between the columns. Repeat the process for the other columns with your final result being below. I like to place the most important graphics first and work-in the ancillary charts and graphs afterwards. Early on you can experiment with placing a main graphic that will help give the piece some visual interest. Give the circles a variety of gradients. I'm using a variety of graphs in this infographic.

10 Tools To Add An Extra Hour To Your Day Voir, toucher, s'approprier les objets de collection Capture d'écran Smithsonian X 3D Explorer "Gunboat Philadelphia" La Smithsonian Institution a lancé tout récemment son fascinant Smithsonian X 3D Explorer. L'outil de visualisation de modèles 3D (développé en collaboration avec Autodesk et d'autres commanditaires) permet d'observer et de manipuler quelques pièces choisies dans l'immense collection des musées de la Smithsonian. Il y a présentement 21 modèles 3D à visionner sur la version Beta de cet explorateur. L'Explorer permet de faire pivoter l'objet modelisé et de zoomer pour le voir en plan rapproché. Il est possible d'avoir accès à des informations sur des détails de l'objet, par exemple pour comprendre les motifs décoratifs d'un artefact, en cliquant sur des points de l'image 3D ou en faisant des visites guidées (à l'onglet Browse Tours) qui les accompagnent.
