Advantage and Disadvantage of Laser Cutting

Laser cutting is an incredibly flexible process, capable of cutting through most materials easily and creating complex designs effortlessly.

Laser cuts create living hinges and other design features not possible with other cuts, while their flexibility also permits close nesting of parts reducing or even eliminating waste.

One of the greatest advantages of laser cutting is its incredible accuracy, which is made possible through its narrow cutting width and focused laser beam, guaranteeing that finished products meet specifications as specified by users. This level of precision can prove particularly helpful when working with intricate designs or intricate patterns.

Laser cutting offers another advantage: versatility. It can cut materials ranging from acrylic and polymers, stainless steel and mild steel, various metals and wood; making laser cutting an excellent solution for manufacturers with diverse production needs.

Laser cutting machines feature computer-controlled programming systems for effortless handling of intricate designs. This allows manufacturers to maximize material usage and produce visually appealing products while cutting waste costs down considerably while decreasing energy use and costs.

Laser cutting machines operate in three distinct modes: linear motion, mixed motion and head movement (or raster). Of the three, linear motion is by far the most popular as it involves moving material along its X and Y axes as the laser cuts through it; mixed motion involves both moving the piece as it cuts as well as its head; finally head motion involves an automated machine moving its laser head directly over the workpiece itself while it’s being cut.


Laser cutting is one of the fastest methods of processing materials and highly precise; therefore, cut edges produced correspond exactly with what was designed. This makes laser cutting ideal for large production runs; however, there are a few downsides associated with its use; most significantly being that specialized training and maintenance must be provided to safely operate the machines used for laser cutting.

Speed of laser cutting depends upon two factors: material thickness and type of laser used. Higher power lasers enable cutting thicker materials at faster rates while water-cooled lasers further increase cutting speed.

Another downside to laser cutting is its space requirements for operation, producing potentially flammable fumes which must be operated in an adequate ventilation environment; this can prove expensive for manufacturers.

Laser cutters can also be used to pierce metals to form holes or features in them, known as vector or etching cutting. This method involves using high-power pulsed lasers to pierce through 13-mm stainless steel sheets in five to fifteen seconds – it provides an efficient alternative to waterjet cutting for various materials.


Laser cutting uses less energy than traditional methods, leading to reduced materials waste and faster production times. Furthermore, maintenance requirements are reduced significantly, creating more consistent and predictable results.

Laser cutting can be used to accurately and quickly cut a variety of materials, including metals such as mild and carbon steel and titanium, plastics and acrylics, and various non-metallic parts. It offers companies an efficient means of producing large volumes of product quickly.

Computer-controlled systems enable laser cutters to traverse material surfaces to cut them using G-code files, which provide instructions to the laser on where and how it should cut the material. G-code files are generated based on factors such as material thickness and speed at which it traverses workpiece surfaces.

Laser cutting can be an extremely dangerous process if left uncontrolled. The heat generated from lasers can quickly burn through materials and cause severe eye damage if reflected back at an inconvenient angle, as well as release toxic and corrosive fumes, which must be properly ventilated during processing. Furthermore, this process creates sharp edges on parts which require additional deburring and tumbling costs that add significantly to project costs.


Laser cutting produces hazardous fumes that may be hazardous to its operators and must be used in an area with adequate ventilation. Furthermore, machines require routine maintenance in order to function optimally – and these devices can be very expensive both to buy and run.

Laser cut material may occasionally appear unprofessional and cause customer dissatisfaction, while its high temperature output could damage machine cases and potentially be fire hazards in flammable materials.

Though laser cutters can be operated without supervision, it is wise to monitor the process closely, particularly as long projects can take hours to finish and any mistakes or faults could cost both time and money. Furthermore, concentrated heat in a confined space could melt materials or cause fires; so having a fire extinguisher nearby is also vital to quickly extinguish any flames.

Laser cutting also requires an additional piercing step before each cut, which can be time-consuming and require precise alignment of the laser beam with the workpiece. Furthermore, some types of complex curves cannot be accurately cut with laser technology.
