My Region - 3-D printer by Sask. man gets record crowdsourced cash A Saskatchewan man who has developed an affordable 3D printer has attracted worldwide attention and more than $700,000 in crowdsourced funding. Rylan Grayston, 28, from Yorkton, said curiosity fuelled his quest to create a 3D copier that sells for just $100. Other high-tech 3D printers sell for several thousand dollars or more. "I didn't have enough money for a 3D printer that I wanted, so I just started thinking about how can I do this myself?" "All I want to do is invent," Grayston said about the possible riches associated with an affordable 3D printer. How exactly does 3D printing work? Although Grayston has no formal training in engineering or computer science, he has been a tinkerer all his life. Rylan Grayston has developed an affordable 3-D printing machine. Grayston's software converts an object into file data using a sound card on his laptop. Unlike other more expensive devices, Grayston's Peachy Printer has no motors or microprocessors.

Common Map Projections Map projections are one of the fundamental concepts of geography and cartography. Selecting the right map projection is one of the important first considerations for accurate GIS analysis. The problem with projections (and the reason why there are so many types) is that it is very difficult to represent the curved 3D surface of the Earth on a flat 2D surface of a map; some distortion is bound to occur (read about what is a map projection). Many geographers through the ages have tried to solve the distortion problem through various map projections. A recent example of a pseudocylindrical projection is the Robinson projection which views the entire world at once and one that compromises both area and angles. Robinson Projection The Robinson Projection was developed by Arthur H. Robinson projection of the world with 15° graticules. A number of map projections have been used throughout history and deciding which projection to use is largely based on what is being mapped. Related: Advertising
Comment une antenne imprimée en 3D pourrait changer Manufacturing 0 Flares Twitter 0 Facebook 0 Google+ 0 Pin It Share 0 LinkedIn 0 inShare0 Reddit 0 0 Flares × Many people question the utility of 3D printers because they believe they’re only capable of printing simple plastic parts. 3D printers are capable of much more. For a while now they’ve been creating objects from glass, ceramic, and metals, among other basic materials. While that opens up doors to many other applications, including tools and parts for jet engines, many people still struggle to see how 3D printing will effect consumer products. Especially in an environment where many of the products we buy have electronics built-in. Think about the products you’ve bought recently or plan to buy in the future. Optomec, a maker of industrial-grade 3D printers, recently announced the development of a solution that allows them to 3D print antennae for mobile devices, directly onto a 3D surface.

The Printer That Can Print A 2,500 Square Foot House In 20 Hours. We have seen huge advancements in 3D printing. We’ve even seen oversized wrenches printed that measure 1.2 meters in length. Now, we can print an entire 2,500 sqft house in 20 hours. In the TED Talk video below, Behrokh Khoshnevis, a professor of Industrial & Systems Engineering at the University of Southern California (USC), demonstrates automated construction, using 3D printers to build an entire house in 20 hours. In manufacturing we use a process called CAD/CAM (computer-aided design / computer-aided manufacturing). 3D models are designed on a computer and then manufactured using CNC Machines or 3D printers. In this video, we see a prototype of a machine called ‘Contour Crafting’ Michael Cooney Michael Cooney, the founder of EngNet, worked as a project engineer for many years sourcing equipment.
COVID-19: Returning to the Workplace. As employers across the United States welcome employees back to the workplace, OSHA has made clear that employers should provide “workers with up-to-date education and training on COVID-19 risk factors and protective behaviors.” Also, several states, such as California, Connecticut, Illinois, Kentucky, Maine (Retail), Massachusetts, Michigan, Minnesota, New Hampshire, New Mexico, New York, Oregon, Rhode Island, Vermont, and Washington, have already mandated that employers provide COVID-19 training to employees, and more states and localities are sure to follow. Some of the state laws require that specific content be included in the training. To learn more about the training content required in your state, contact us. Clear Law Institute’s interactive online training, COVID-19 Safe Workplace, helps employers comply with federal and state training requirements and promote a safe workplace.
Comment projeter sur la géométrie 3D Russian | French | Italian Note that due to the manual nature of the described approach your results will not be perfect, but can be quite good depending on your patience. Introduction All the above mentioned topics deal with the same problem: Find the pose (position, orientation) of an object or the pose and lens characteristics (field of view, shift) of a camera viewing that object. In cinematography with 3d visual effects the terms "match moving" or "camera tracking" are used to describe the problem of matching a real world scene with its virtual counterpart in order to mix them together seamlessly. For realtime computergraphics the ARToolKit provides a way that works for certain situations (see ARTK+Tracker? Projection on a flat surface Note: Like this you can always get a correctly looking projected image on a flat surface independent of the projectors position, orientation to the surface and its lens characteristics. Projection on an arbitrary surface Virtual replica of the real scene
Vader Systems invente l'imprimante 3D métal à destination du grand public Du fait d’une température de fusion bien supérieure au plastique (de 600°C pour l’aluminium jusqu’à 1000°C pour l’or), la possibilité d’offrir aux particuliers une imprimante 3D à base de métal restait en suspens. La société Vader Systems, créée par le père Scott et le fils Zach Vader, pourrait bien mettre un terme aux doutes qui subsistaient. La technologie utilisée par Vader Systems, dénommée « Liquid Metal Jet Printing » (impression par jet de métal liquide), est une version détournée de l’impression par jet d’encre, bien connue des imprimantes 2D. Des minuscules gouttes de métal sont déposées sur une plateforme, suivant un tracé préalablement spécifié. Comme pour chaque technologie d’impression, l’objet 3D est alors construit par une succession de couche de matière, et dans ce cas précis, de métal. L’impression 3D à partir de métal n’est pas nouvelle, elle existait déjà dans l’industrie par le biais du frittage laser direct de métal. Le lien vers le site de Vader Systems ici.

Update December 20th: By request I’ve created a 15 minute screencast explaining most of these steps.

Comment l’impression 3D va révolutionner le monde et le retail The Micro : une imprimante 3D fait un énorme carton sur Kickstarter Ils ne demandaient qu'à recevoir 50 000 dollars en un mois pour passer à la production. Finalement, la start-up américaine M3D a déjà obtenu plus de 1,6 millions de dollars sur Kickstarter, moins de deux jours après la présentation de son imprimante 3D "The Micro", qui se veut être une imprimante à la fois accessible financièrement et très facile à utiliser sans rien connaître à l'impression 3D. Son énorme succès, qui n'est pas dû à une révolution technique mais à plusieurs atouts cumulés, confirme l'intérêt spectaculaire porté aux imprimantes 3D très grand public, comme l'avait déjà montré la Buccanneer, qui avait elle-même bénéficié de 1,4 millions d'euros levés via Kickstarter. Côté technique, The Micro est dotée de capteurs qui automatisent les processus les plus complexes de calibration des imprimantes 3D traditionnelles. Une imprimante 3D plug&play L'imprimante sera vendue 299 dollars.
