Even it is particularly special, but actually not a difficult technique (especially when using a pure material). Some of the classic examples are boat, barrel and container types. The native Indian of the American traditionally bends a wood to make a snowshoes, sledge, luge and canoe. In Europe, this technique already been used for a long time in the making of chair such as the slat back chair and the ladder back chair that already existed in the middle ages (1100-1450) and often could be seen in their wood block print and the copperplate print. Nowadays, there are various designs for chair with a value-added element, and to make it as a product, the need to learn the manufacturing technique and its application becomes very important.
Type of bending process Bending process such as a heating method, depends on the different of the method used, could be classified as below. 2.Kerfing. Layer by Layer. Buildup: GE made the aircraft engine component on the left by using a laser to melt metal in precise places, beginning with the single layer seen on the right.
The parts in jet engines have to withstand staggering forces and temperatures, and they have to be as light as possible to save on fuel. That means it’s complex and costly to make them: technicians at General Electric weld together as many as 20 separate pieces of metal to achieve a shape that efficiently mixes fuel and air in a fuel injector. But for a new engine coming out next year, GE thinks it has a better way to make fuel injectors: by printing them. To do it, a laser traces out the shape of the injector’s cross-section on a bed of cobalt-chrome powder, fusing the powder into solid form to build up the injector one ultrathin layer at a time. This promises to be less expensive than traditional manufacturing methods, and it should lead to a lighter part—which is to say a better one.

Life Rafts and Leviathan™ [Biohabitat's floating habitat mattresses made of 100% recycled plastic bottles, seen here filled with soil and plants by a team of volunteers and ready for deployment as experimental land makers near the Isle de Jean Charles, Louisiana.
Image source] As recently reported by America’s Wetland Foundation: “Hundreds of volunteers helped launch 187 “floating islands” in a demonstration project of new technology to protect the area south of Houma, Louisiana, that is considered to be “ground zero” for coastal land loss in America. The islands offer promise, not only to protect existing land against eroding wave action, but also as a means of building new land in shallow open waters in an area that has suffered some of the nation’s greatest loss of land.
The five-by-eight-foot islands [were] planted with 40-60 native plants by volunteers, then anchored end-to-end for 1,500 feet next to remaining marshes on the thin strip of road that leads to Isle de Jean Charles, south of Houma. Living Paper-Free and Loving It: 15 Tips for Creating a Paperless Home. “Use it up, wear it out, make it do, or do without” [I] detest useless waste.
It literally makes me crazy to think of spending money on something — usually out of convenience – knowing that the end result will be the trash. Paper towels, diapers, wipes, disposable anything, and yes even toilet paper…for nearly a year our family has been on a mission to find sustainable replacements for these common household items in an attempt to create a paperless home. Many people will argue that purchasing and using paper products doesn’t effect their budget enough to warrant seeking reusable alternatives. After pricing out these items in a local grocery store, I estimate our paperless home is saving nearly $40-$50 per month. 15 Tips for Creating a Paperless Home Important disclaimer: Don’t pressure yourself into implementing each one of these tips all at once…you’ll only end up frustrated and defeated. Here are a few of my ideas for creating a paperless home: In theory 1. 2. 3. 4. 5. 6. . 7.
