A laser cutter is an industrial machine that uses a thermal process in which a focused laser beam is used to melt materials in a localized area. In such a process, a continuous cut is achieved by moving the laser beam or the workpiece under Computer Numerical Control (CNC).

The Theory 

Laser cutter makes use of energy released on the time when laser beam irradiates metal surface. The metal is thereby, melted by the laser; the sinters get blown away by the force of gas. As the laser power is highly concentrated or focused, only a minimal heat affects the other part of the metal plate, thereby causing little or no deformation.

What Does The Machine Do?

A laser cutter can be described as a prototyping as well as a manufacturing tool mainly used by engineers, artists and designers to etch and cut into various flat-surfaced materials. The machine uses a focused but thin laser beam to cut through and pierce materials; to cut patterns and geometrics detailed by designers.

What Are The Things That Laser Can Cut Through 

The popularity of laser cutting is based on its versatility. Laser cuts through a variety of materials such as wood, paper, cork, foam, acrylic, plus other different types of metals.

Can Laser Cut Humans?

You may be wondering if a laser can cut humans. You are right if you have guessed that the consequence that strong lasers have on flesh varies with the wavelength or light colour and the period of the pulses produced. However, research findings have disclosed that lasers can cut actual flesh by causing a series of lapping micro explosions.

Material That Cannot Be Cut by a Laser? 

Polycarbonate is not a suitable material for cutting with laser. ‘ABS produces cyanide in gaseous form, and it typically melts so ABS doesn’t cut properly in laser cutters. It melts instead of getting vaporized and has a good chance of catching fire and depositing melted, gooey substances on the laser cutting grid.

What Is The Thickness of Materials That laser Can Cut?

Most laser cutters are able to work on materials in the range of 0.5-12 mm thick. However, some other lasers have the capacity to cut materials as thick as 20 mm.

The Disadvantages 

The shortcomings of laser cutting process are:

*   Compared to other cutting processes, the power consumption by laser cutter is on the high side.

*   Handling of the laser beam is very delicate.

*   If the laser beam comes in contact with the human body, it can be harmful.

*   Cutting of thick metal can still not be done with a laser cutter.

Last Thoughts

This discussion will be incomplete if we don’t mention the financial benefits. The laser cutter has brought about ease of business in many fields. Those who have the technical know-how have used it as a money spinner. 

A laser engraving business is lucrative. It is easy to set up, with lots of business opportunities. All that you require is a laser engraver, ideas of products, and a market medium, and you are good to go.
