This refers to your editorial 3Ds future (FE, September 24). It is not known whether composite productsrequiring different raw materialsare also going to be produced by 3D printing, though theoretically, it is possible. As it is, we may print shirt buttons, but not shirts that require various materials in various quantities. It is going to be very interesting. Candy manufacturers, textile designers and such entities will be pleased. But what about Coke and Pepsi Would they also prefer a 3D printing model If so, a printer vended to each outlet would do the trickbut supply of raw material would involve the same logistics and headache. And, there is the danger of leakage of trade secrets for the companies. And, you can already hear the leftists whining about the need to regulate this industry. Suppose the 3D printer can generate a report that is going to show the organisation as a very compliant entity, they are going to have a very difficult time getting the corporates fall in line! More interesting would be whether a 3D printer can be used for producing another 3D printer! If so, one may purchase only one printerand then replicate it to produce some n number of printers. Using this, he can mass-produce components to achieve economies of scale! This would be a game of cloning.
Interesting times ahead.

This refers to the news report Prices of key commodities go up on geo-political tensions (FE, September 26). The attempts to produce new and innovative crops should be actively encouraged because consumption levels are on the rise across the world. However, at the same time, one can understand the possible risks and consequences any genetically-modified crop may bring in, especially since the studies on the same are still ongoing. If independent scientific studies can establish the safety of improved varieties of crops and genetically-modified ones, it is the responsibility of the government to introduce such crops to the market.
