Printing Stuff

Cheaper way of lighting up...

Imagine you need a square meter of light, perhaps for a single ’tile’ on the ceiling that emits lights at your building. You’d probably get contractors to make a box with circuits inside that connects to a couple of fluorescent tubes (or if you’re quite rich, a couple of LEDs) and then cover the thing with a translucent white piece of acrylic. The entire structure is bulky and probably quite energy consuming. Now, scientists have found a way to make a ‘sheet’ of LED that would allow you to make that ‘lighted tile’ much more easily and is also much more compact. Essentially, the technology allows you to print a circuit that is wired in a way that acts as a diode, and one that emits light.

And since we’re at the issue of printing stuff; we mentioned previously about industrial prototyping machines that churns out 3D structures/models. I was quite intrigued by the idea of being able to print out a peg for your clothes or even design a shoe that fits you perfectly. But perhaps even more amazing would be the ability to print out cells, tissues and even organs as reported by The Economist.

The article mentioned about growing organs from scratch and raised the example of bladders being grown from original cells of patients. Essentially the patients are donating organs to themselves; the same applies for the printing of organs. The idea is appealing because there’s nothing artificial about them beside the involvement of doctors in the process of growing the cells and putting them together – ultimately the organ is still organic and from the patients. Perhaps then, Iran’s model for kidney donation won’t be so appealing anymore.
