Mark One: Carbon Fiber 3D Printer | News 3D printers are evolving ridiculously fast, and here’s the next step, a 3D printer that prints in carbon fiber. The best thing is that It’s only going to cost $5000, which is comparable to regular 3D printers on the market. The desktop printer is also capable of printing in fiberglass, nylon, and the thermoplastic PLA, as well as a composite of these materials with layers of carbon fiber added for strength. The main advantage of the Mark One: It can print parts 20 times stiffer and five times stronger than ABS, according to the company. It even has a higher strength-to-weight ratio than CNC-machined aluminum. The MarkForged Mark One will be up for pre-order starting in February. Comments: comments

What material should I use for 3D printing? | 3D Printing for Beginners This article will give you a quick overview of the current consumables used in 3D printing and will explain the main differences in terms easily understood by beginners. As explained in our previous article “What is 3D printing?”, there are mainly two sorts of 3D printers, the industrial-type printers and the consumer-oriented 3D printers, a.k.a. desktop 3D printers. The present article will only focus on the most common consumables used in consumer 3D printers using the FDM (fused deposition modeling) technology. A traditional inkjet printer needs ink cartridges in order to be able to print – the situation is similar for 3D printers, except that 3D desktop-type printers need plastic filament. These consumables are mostly available online in a variety of types of material (ABS, PLA, PVA, etc.), colors, diameters and lengths. What you will learn: Note: the more exotic printing plastics like polycarbonate (PC), high-density polyethylene (HDPE) or nylon are not discussed in this article.

Réalité augmentée et interactivité : vecteurs de révolution pédagogique ? Lorsque l’on enseigne, la tâche la plus complexe est celle qui consiste à différencier les apprentissages, c’est-à-dire de permettre à ce que chaque élève ait accès, au sein d’une même séquence, à une leçon la plus personnalisée, la plus individualisée possible. L’objectif est donc de prendre en compte les différences inhérentes à chacun tout un atteignant, pour le groupe classe, un objectif commun. Chaque élève est, par essence, différent et dispose d’une façon d’appréhender le savoir transmis qui lui est propre : on appelle cela les styles cognitifs. Le canal de transmission pédagogique le plus approprié, pour les élèves privilégiant la vue et/ou le toucher dans leur manière d’apprendre, serait de favoriser la manipulation et/ou la visualisation, ce qui n’est pas toujours aisé : leçons sur le corps humain ou sur les volumes par exemple. Peut-être que, comme le suggère Michel Guillou[1], il faut casser tout cela.

‘Anti-Gravity’ 3D Printer Uses Strands to Sculpt Shapes on Any Surface 3D printers build objects by cross-section, one layer at a time from the ground up—gravity is a limiting factor. But what if it wasn’t? Using proprietary 3D printing materials, Petr Novikov and Saša Jokić say their Mataerial 3D printing system is gravity independent. The duo’s method allows a robotic arm to print objects on floors, walls, ceilings—smooth and uneven surfaces. Novikov and Jokić invented their system (patent pending) in collaboration with the Institute for Advanced Architecture of Catalonia. In contrast to the 3Doodler, Novikov and Jokić’s system is a software-controlled 3D printer. Why is this an improvement on current tech? Novikov and Jokić say, "This method gives us a flexibility to create truly natural objects by making 3D curves instead of 2D layers. Whether the system can print a wide variety of shapes isn't shown in the video. But the concept is cool, and the tech will likely improve. Image Credit: Mataerial

The Difference Between ABS and PLA for 3D Printing Don't forget to check out our 3D Printer Filament! It's made with love and care by us especially for you right here in the USA! See our Everyday Printing Materials, including Advanced Ingeo PLA and 5 Dollar Filament - our initiative to make it affordable to stock up on a variety of colors and materials. You've got a 3D Printer, or you're looking to buy a 3D Printer and each one seems to indicate it prints in either ABS, PLA, or both. Some Common Ground There are many materials that are being explored for 3D Printing, however you will find that the two dominant plastics are ABS and PLA. Now while there are many thermoplastics, very few of them are currently used for 3D Printing. The first test, that of production from base plastic resin into top-notch Plastic Filament such as what we carry is a strict and carefully monitored process. Here is where the two plastics divide and will help to explain why different groups prefer one over the other. Storage Smell Part Accuracy In Summary

Manuels scolaires sur iPad : combien ça coûte vraiment ? Apple essaye de positionner l’iPad dans les écoles américaines grâce aux manuels scolaires qui seront créés sur iBooks Author mais aussi grâce à la nouvelle version de iTunes U. L’argument économique des manuels proposés à moins de 15 $ est censé séduire, et permettre à Apple de tenter d’équiper un maximum d’élèves américains de leur célèbre iPad. Mais chez onlineteachingdegree, on a sorti les calculettes, et une fois pris en compte le coût de l’iPad, le passage au numérique à la sauce Apple est loin d’être à portée de toutes les bourses. Que l’achat d’iPad soit financé par les contribuable US, les écoles ou des utilisateurs eux-mêmes ne change rien, le coût serait presque 2 fois et demie supérieur, dans le cadre d’une acquisition de manuel papier neuf tous les 5 ans, ou d’un iPad tous les 4 ans. Si le pays décidait d’équiper tous les élèves, il faudrait débourser 27 milliards de dollars rien qu’en tablettes, un chiffre qui couvrirait le salaire de 650,000 professeurs.

Turn Your Plastic Recyclables Into 3D Printing Spools With Filabot Source: Filabot 3D printers are getting cooler every day, but there’s one component integral to 3D printing that normally gets overlooked – that is, until you have to pay for it. As many 3D hobbyists have no doubt discovered, the one time cost of the printer can be quickly dwarfed by feeding it spool after spool of raw plastic. At $40 or more per spool, an avid hobbyist can see his or her enthusiasm rapidly diminished. Maybe Filabot won’t revolutionize how 3D printing is done, but how often it is done. Filabot is a 3D plastic extrusion system that takes all kinds of recyclable plastic – milk jugs, soda, detergent and shampoo bottles – and turns them into raw material for 3D printing creativity. Not only will your household recyclables now appear as treasure troves of cheap and virtually endless supply of 3D printing plastic, all those projects that didn’t print right, cracked, or just didn’t turn out the way you thought it would can now be given a second chance at greatness.

NACE - The Skills and Qualities Employers Want in Their Class of 2013 Recruits Spotlight for Career Services ProfessionalsOctober 24, 2012 What skills and qualities are employers seeking in the graduates they’re recruiting from the Class of 2013? Above all, they’re looking to hire candidates with outstanding communication skills and who are team players, according to results of NACE’s Job Outlook 2013 survey. The top five skills/qualities employers report seeking are the same as last year, although the order has been somewhat shuffled. In this year’s survey, participants rated “ability to verbally communicate with persons inside and outside the organization” (second in Job Outlook 2012) and “ability to work in a team structure” (first in Job Outlook 2012) as the two most important candidate skills/qualities. These are followed by candidates’ “ability to make decisions and solve problems,” “ability to obtain and process information,” (fifth in Job Outlook 2012) and “ability to plan, organize, and prioritize work” (fourth in Job Outlook 2012).

3D printer makes a teddy bear with needle and thread - tech - 15 May 2014 FROM aircraft to houses and even guns, just about anything can be 3D printed – as long as it's not soft and squishy. Now the repertoire is about to get a lot more cuddly. The first 3D printer that can churn out soft objects made its debut last month at the Computer Human Interaction conference in Toronto, Canada. "The things that we hold close to our body, we would like them to be soft," says Scott Hudson at Carnegie Mellon University in Pittsburgh, Pennsylvania, who led the team that devised the printer. Initially, the machine could only work with melted plastic. To go beyond making teddy bears, the printer must be able to combine yarn with other types of material. The team is also experimenting with ways to embed electronics inside the bears without puncturing the circuitry or breaking the print needles. The soft printer is an great example of how far such machines have come, says Stephen Ervin of the Harvard University Fabrication Laboratory. More From New Scientist More from the web
