5 Frequent mistakes of laser engraving and how to avoid them

Knowing how to avoid these mistakes and not repeat them is half the battle. With that in mind, let’s explore the five most common mistakes in laser engraving and how to avoid them in future projects.

Error 1: The laser cutting machine is heated when trying to melt it.

The first step in preventing the burning fabric with laser engraving equipment is to understand which fabrics can withstand the process and at any temperature. Thick materials such as cotton, canvas and leather will tolerate more powerful engraving conditions. However, when it is involved in a fragile fabric, it is essential and low power change at a high speed. Test these initial modifications on each waste item, if the fabric can handle it, steadily increase the power before getting the result you are looking for.

Error 2: Acrylic does not produce white engraving

Other types of acrylic acids for laser engraving extruded acrylic, and the shape of the machine in the machine. Extruded acrylic acid is usually cheaper than molded acrylic because it can produce it in large amounts. However, the laser engraving device responds very different. This acrylic acid is clean and uniformly cut and produces flame polishing edges; however, when photographed, it does not produce cold appearance, but a clear engraving. Therefore, if you want to get a frosty white appearance, make sure to use acrylic molding facing.

Error 3: Irregular engraving of glass

Typically, when the laser engraving hits the glass, it will crack the surface but not fully engraved or stripped the substance required for absolute etching. The broken glass surface provides ice-cold appearance, but it may be rough and divided, depending on the type of glass you are using. Although the cold appearance is a bit attractive, it cannot be said to be rough or splitting. In order to achieve unified frost, try one or more tips below:

Typically, the paper or wet tissue is placed in the etch region to help heat dissipation and increase the etching operation. Simply make sure you put it on top, you won’t leave wrinkles on the page. The thin layer liquid soap is applied to an area in which heat is etched in some manner.

Whether it is a thumbnail or a paper towel. Finally, if there is a glass chip after the carvings, polish the sponge to polish the area, these sponges have no itch.

Error 4: Wood engraving is inconsistent in the same setting. 

Similar woods have different reactions when they engrave lasers and different effects. Lighter trees such as cherries or maple, when cutting or engraving more dense trees, providing a good contrast in the area of laser engraving requires more laser power.

The following is the secret of wood carving:

Natural wood engraving in the process of being trapped in the wood, is causing smoke and debris during being trapped in the wood. In order to reduce this impact, it is usually started from bottom to start, as this helps to distinguish the smoke away. When you burn wood, after burning, use a wet cloth to clean excess smoem and ashes.

Error 5: Laser cutting head is no longer as fast as before.

Clean your tools! As for most construction equipment, the system achieves greater performance than unsuitable equipment. Maintenance specification in the user manual for laser cutting machine. If the output is rapidly declining, the test and cleaning optical components can be the first step in correcting problems.

It is recommended to check the laser optical components (lens and mirror) per week, if possible, clean. If you cut products containing larger volume, such as wood or acrylic acid. These elements need to be cleaned regularly. Typically, optical components are light colored, color and gloss. If they are opaque or with stripes and debris, it is time to patch them.
