How long does laser cutting last?

Laser cutting is the process of creating patterns, designs, symbols, etc. by using a powerful laser beam on the selected material. The laser beam melts, burns, or vaporizes the material to bring out the desired shapes and patterns. This process is generally conducted through the careful and effective use of laser cutters. Laser cutters can finish the cutting within just a few minutes.

How long do laser cutters last depends on the stated power level (wattage). As a result, different laser cutters will have different lifetimes. In most cases, the laser tubes become degraded over time.

So, the output wattage declines, and component failures may occur. There are also other factors related to the durability of laser cutters that influence their lifetime of usage.

Factors Affect The Lifespan Of A Laser Engraver

Quality of the Machine

This is the most important factor. CO₂ laser engravers tend to have a longer lifespan than diode laser engravers. This is because CO₂ laser engravers use higher quality materials. A fiber laser’s module often lasts three times as long as other technologies. Fiber lasers can last up to 100,000 working hours.

Frequency of Use

The more you use your laser engraver, the shorter its lifespan will be. If you use your machine occasionally, it will last longer than if you use it daily. If you use it for commercial purposes, it will likely need to be replaced sooner than if you only use it occasionally.

Maintenance and Care

Proper maintenance and care is essential for prolonging the life of your machine. Be sure to clean it regularly and keep all the parts properly lubricated.

Environment

The environment in which you use your laser engraver will also affect its lifespan. If you use it in a dusty or humid environment, it will wear out faster than if you use it in a clean and dry environment.

What You Engrave

The material you engrave will also affect the lifespan of your machine. Softer materials like wood or plastic are easier on the machine and will not cause as much wear and tear. Harder materials like metal or glass will require more maintenance and care and likely need to be replaced sooner.

Proper Maintenance of Laser Engraver

Proper maintenance of the optics of a laser engraver ensures quality results.

The accumulation of dust and debris on the focusing lens can diffuse the laser and produce low-quality engraving even after setting the optimal parameters.

This affects the quality by producing a low-contrast engraving and reduces the material removing capability of the laser, thereby affecting the durability of the engraving.

Therefore, it is important to clean the mirrors and lenses of the laser engraver regularly to attain the best engraving.

Protective Coating

Sealing the engraved surface with a protective coating can help improve the life of the engraving.

These protective coatings prevent the direct contact of the engraved surface with the abrasive particles, thereby protecting the engraving from scratches.

Although these coatings do not make the surface immune to damage, selecting a suitable coating for the material can enhance the durability of the engraving.
