3D-skrivare - Vetenskap & miljö
Möjligheten att tillverka fysiska föremål med hjälp av så kallade 3d-skrivare har utvecklats fort de senaste åren - alltså maskiner som till skillnad från vanliga skrivare skriver ut 3-dimensionella objekt - i olika material och färger. Tekniken spås nu föra med sig en revolution både inom tillverkningsindustrin - och i hemmet: – Det här är framtiden, säger tandteknikern Felix Farhadi i Hamburg. Hans jobb är att polera tandkronor som precis skrivits ut av en 3d-skrivare. Dagen innan skickade tandläkaren över en 3d-ritning på tanden till företaget där Felix jobbar och några timmar senare är en exakt kopia av patientens tand färdig. Verktyget är ljus. Det började för 10 år sen med tänder, för 3 år sen blev det knäproteser och höftinplantat - och nu - tillverkas avancerade motordelar och delar till flygplan med hjälp av 3d-skrivare, och det i former som är omöjliga att tillverka med traditionella metoder.

TOP 10 IMPOSSIBLE INVENTIONS THAT WORK « Revolutionizing Awareness
Searl Effects Generator by Jeane Manning When Leonardo da Vinci sketched out an impossible invention, fifteenth-century scholars probably put him down. Forget it, Leon. Throughout history, experts tell innovators that their inventions are impossible. Perhaps in the 21st century the following inventions will be standard science, and a history student may wonder why 20th-century pundits disregarded them. This class of inventions could wipe out oil crises and help solve environmental problems. Forget the Rube Goldberg mechanical perpetual motion contraptions; they had to stop eventually. Inventors give various names to their space-energy converters. A spiritual commune in Switzerland had a tabletop free energy device running in greenhouses for years, but members feared that outsiders would turn the technology into weaponry. It may have been done before Tesla’s time. The garage inventors come from many backgrounds. One example is U.S. In 1923 Townsend T. 8.
3D printing - WIKI
An ORDbot Quantum 3D printer. 3D printing or additive manufacturing[1] is a process of making a three-dimensional solid object of virtually any shape from a digital model. 3D printing is achieved using an additive process, where successive layers of material are laid down in different shapes.[2] 3D printing is also considered distinct from traditional machining techniques, which mostly rely on the removal of material by methods such as cutting or drilling (subtractive processes). A 3D printer is a limited type of industrial robot that is capable of carrying out an additive process under computer control. The 3D printing technology is used for both prototyping and distributed manufacturing with applications in architecture, construction (AEC), industrial design, automotive, aerospace, military, engineering, dental and medical industries, biotech (human tissue replacement), fashion, footwear, jewelry, eyewear, education, geographic information systems, food, and many other fields.

3D-printer inte längre science fiction | Innovation
Det kallas för 3D-print och veteranerna i branschen har varit med sedan slutet av 1980-talet. Då handlade det om att på ett smidigt sätt ta fram prototyper i plast men sedan dess har tekniken förbättrats och fått nya användningsområden. – Det som har hänt är att vi nu har en betydligt mer avancerade teknik som ger en helt annan kvalitet. Det betyder att vi börjar kunna producera saker som kan användas i slutprodukter för den vanliga konsumenten, säger Evald Ottosson på teknikföretaget Protech. – Det som sker nu är det jag drömde om för 20 år sedan. Han tror att vi inom en inte alltför avlägsen framtid kan ha 3D-printrar i exempelvis bilverkstaden för att producera reservdelar. – Tänk dig att du tar bilen till verkstaden för att få en reservdel utbytt. Han berättar om hur han själv nyligen använde sig av en 3D-printer för att laga en leksak som gått sönder. – Sambons barnbarn hade fått ett tält som gått sönder, det var det där krysset i toppen som hade spruckit där pinnarna går in.
10 Tips for Monetizing Social Traffic Through Virtual Currency
This is a guest post by Anu Shukla, CEO of Offerpal Media. Offerpal Media is a leading “managed offer platform” for social applications, virtual worlds, games, and community-oriented websites. The Opportunity A new boon is taking place on the Internet. For community-oriented web publishers like social networks, social applications, virtual worlds, MMOGs and other social properties on which traditional advertising has produced such little revenue per user relative to other sites, a new market, led by the proliferation of virtual currency and virtual goods, is rapidly expanding. No one knows yet the exact size or potential of the market, though even conservative estimates put it at well over $2 billion. What’s behind the boon? virtual goods are the most effective way to monetize traffic on their properties. Today, there’s little doubt that virtual currency is the most effective way for social web publishers to monetize their traffic. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Conclusion
3D Printers that Don't Suck | Wired Design
Early desktop printers were horrible. For the price of thousands of dollars one got lo-res dot matrix printouts on paper that had tractor-feed holes punched into the margins. It wasn’t pretty, but those early models paved the way for high-resolution, low-cost laser printing. Left – Fused Filament Fabrication (FFF)/Right – SLA. Same model, same size, very different results. Today’s hobby grade 3-D printers are similarly crude. This new type of hobbyist printer use Stereolithography (SLA) technology, utilizing light instead of heat to make models. The resolution of new 3-D printers far surpass the first gen systems. This pioneering technology brings three much needed improvements to home based 3-D printers: 1. Parts made on SLA systems are much higher resolution than prints from FFF machines which have bumpy, ridged surfaces. Also, since the light hardens the plastic simultaneously, the only factor impacting print speed is the height of the object. 2. 3. Yes, There Are Downsides B9 Creator
