Why Are Blades Used For Printing?

Tags:

As almost everyone knows these days, printers are incredibly complex machines that are meticulously crafted with intricate detail and precision. It should be obvious that the bigger the printer is, the more complex it becomes, and that is only further complicated by what it is being printed. Of course, even with knowing how complex printers are, you might not have the slightest inkling as to what is really inside them. Ink probably comes to mind, perhaps even some form of a lens, but other than that, you might be completely clueless of whatever else they contain. Therefore, you might be surprised to learn that there can actually be blades inside some of them.

Why?

When hearing that a blade might be in a printer, your first reaction might be to question why. While this is certainly a valid inquiry, you should be relieved to know it is not for any nefarious purposes. In certainĀ printers, a cylinder is covered with ink and is rolled across the desired material, and the excess ink is then essentially sheared off. This prevents a build-up of ink, as well as prevent the image from smearing.

What Kind?

Next, you might be wondering what sort of materials these blades are made of. A far cry from the metallic swords and knives that might have sprung to mind, these sort of blades are typically either a plastic orĀ composite blade. The plastics can be nylon, delrin, or ultra high molecular weight polyethylene, and the composites can be mylar, fiberglass, or graphite.

Blade Shape?

It be even more surprising to learn that the blades themselves can have different edges depending on their requirements. They might have a seal relief, unhoned, or standard edge. Each has it own use and specific purpose.

This is only one component of printers, so be sure to appreciate just how complicated these machines truly are.
