The demand is growing due to some of the revolutionary benefits that it can provide. Like almost all technologies it has its own drawbacks that need considering. This page aims to help with the selection process.
What are the Advantages and Disadvantages of 3D Printing?
Metal fabrication refers to the processes and techniques required to design, create and assemble a metal structure. While welding — or using heat and pressure to fuse metal-based materials — is an essential component of the metal fabrication process for some projects, using the terms welding and metal fabrication interchangeably is like using the words fireplace and living room interchangeably. Laser Cutting Laser cutting is one of the most precise methods of cutting a design from a variety of different materials. The CNC machine, which does the cutting, is programmed to cut whatever design the client wants. From simple rectangles to precise, intricately designed pieces, laser cutting is your best option for most applications. CO2 Laser Cutting CO2 lasers are the highest-power continuous wave lasers that are available on the market. Because of their high power, they are ideal for cutting and boring.

What Are the Advantages & Disadvantages of Diode Lasers?
Communication in space. Laser communications systems are wireless connections through the atmosphere, The light speed is the fastest speed than anything can travel, so laser communications and laser sensing are important in mortar defense and other crucial aerospace and defense applications. Lasers are able to see through the dense foliage, and they can allow for space communication from distances measured in millions of miles, We use lasers everywhere such as in the military systems, the avionics and in submarines. Laser communications are better than radio as light wavelengths are packed much more tightly than the sound waves and they transmit more information per second with a stronger signal, Lasers are used in communication with the optical fibers instead of telephone cables.
This difference allows lasers to focus light and energy on very small surfaces, even on far-away objects -- a unique characteristic that lends itself to various applications. Aside from their various applications, lasers are classified according to how they emit light. Their classification basis also stems from the medium or materials used as a source of light, whether gas, solid-state or diode lasers. A relatively recent development in laser technology, diode lasers use semiconductors -- usually microscopic Gallium-Arsenide chips -- as a medium.
The first laser eye surgery dates back to approximately 30 years. However, it is still considered to be a relatively new method of operating eye related disorders.

Плевал я на Стратмора! - закричал Чатрукьян, и его слова громким эхом разнеслись по шифровалке. - Мистер Чатрукьян? - послышался сверху звучный возглас. Все трое замерли. Над ними, опираясь на перила площадки перед своим кабинетом, стоял Стратмор. Какое-то время в здании слышался только неровный гул расположенных далеко внизу генераторов. Сьюзан отчаянно пыталась встретиться взглядом со Стратмором.
Она знала, что он перемножает цифры и намертво запоминает словари, не хуже ксерокса.
