Laser cutting is a process that uses a focused beam of light to cut through materials. The type of laser used depends on the material and the machine configuration.
There are several types of lasers available and each has its own set of advantages and disadvantages. Some have high wattage, while others are more expensive and require maintenance.
Cost
Laser cutting is a sophisticated technique that delivers quick results while creating minimal waste. It requires precision to ensure accurate cuts and can be done with any type of material, ranging from wood to metal.
The cost of laser cutting depends on several factors, including the amount and type of materials, the size of the parts to be cut, and the quality of the surface. It also varies by machine type and the overall time it takes to process the job.

Precision
Whether a part is made out of sheet metal or wood, laser cutting can be used to create exact cuts that would otherwise be impossible. This versatility is a key reason why this method is so popular and important to many manufacturing industries.
Aside from its versatility, lasers are also extremely precise, ensuring that parts are cut without leaving any defects. They’re especially effective when cutting hard materials, such as steel and brass.
Today’s precision laser cutting machines can focus on about 25 microns, or less than 1/4 of the width of a human hair. The cut width can be very small (less than 0.001 inch) and the dimensional accuracy is extremely accurate (around +- 0.0005 inch).
Moreover, modern machines deliver a minimal heat affected zone, allowing for more reliable and predictable components. This can help manufacturers avoid thermal distortion and mechanical distortion risk, particularly when working with thinner materials.
Safety
Laser cutting machines are incredibly powerful and can cause severe burns to anyone who touches the laser, or enters the machine room without proper safety precautions in place. Therefore, it is essential to ensure that all workshop members follow safe operating procedures and wear suitable laser protection equipment, such as Class-1 Laser Light approved safety glasses.
The operator should also understand the hazards of using a laser cutter, and follow the user manual instructions carefully to avoid accidents. For example, the lid of the cabinet should always be closed when the laser is switched on.
A ‘back reflection’ system is usually used in modern equipment to detect if the beam is being reflected by a sheet of material and automatically shut off the laser before any damage is done.
A properly-maintained fire extinguisher should also be kept nearby, as laser cutters can also produce fumes that are potentially toxic. In addition, keeping a clean and clutter-free workshop will minimize injury risks.
Environmental impact
LASER CUTTING is an environmentally friendly process that reduces the amount of raw materials needed to create a finished product. This saves on energy costs and less waste is produced overall.
Unlike metal stamping, laser cutting does not require lubricant to protect the sheet metal from surface abrasion, which can help reduce environmental pollution and health issues.
In addition to being an environmentally friendly process, it is also a good way to reduce waste in businesses. By using less raw material, the production of a product can be much quicker and more efficient.
In order to prevent the harm that can be caused by laser cutting, it is important to have air filtration systems in place and install HVAC exhaust systems. Businesses of all sizes, schools, and even independent artists who specialize in laser cutting should be sure to install these systems in their workspaces.
