In the News (from The Financial Times): “To date, companies have mainly used 3D printing, also called additive manufacturing, to make prototype parts and products for testing. But several of the world’s biggest manufacturers, such as General Electric, EADS and Siemens, are now leading the way in moving the technology from the design shop to the factory floor.
“From January, Siemens, the German electronics and engineering group, will use 3D printing to make spare parts and other components of gas turbines within its power generation service and maintenance division. It can produce more than 100 different individual parts this way. As a result, some repairs can be done in a tenth of the usual time.
“Siemens believes 3D printing could “revolutionise” the supply of spare parts. Today, spare parts are mass produced, stored and sent out individually as required. Soon they will be able to be printed exactly where they are needed – close to the customer. …
“For the aerospace industry, 3D printing is particularly attractive as it can produce lighter parts. In addition, the technology can also help reduce material wastage – important for an industry that uses high-cost metals such as titanium. As a result, products that have a poor ‘buy-to-fly’ ratio are likely to be at the top of companies’ lists for 3D printing.
“’For some of our components you can throw away 90 per cent of the material that you buy,’ says Rich Oldfield, technical director of GKN Aerospace. ‘If you look at the bill of material on an aircraft, anything that has got a buy-to-fly ratio in that 70 to 90 per cent space is a candidate. That’s a huge opportunity.’”
My Comment: All this is not intended to increase profits, but to free people for re-education. Nature has outlined the purpose and means: to bring the human being to it through the recognition of evil, from the direction opposite to this goal.
