Wood laser engraving
Wood is by far the most commonly used item for laser engraving. It is a natural material containing fiber and cellulose. These molecules melt or burn when they come into contact with a powerful laser. Therefore, you can easily form various designs on wooden boards even with low power laser equipment. Another benefit of laser engraving wood is that the partial burning of the cellulose produces elegant burn marks and texture on the surface, making it very beautiful.
However, different types of wood have their advantages and requirements. For example, you need a relatively high laser power to engrave on hardwoods, not softwoods like balsa, even with a 25W laser module. In any case, it is important to consult your supplier about laser engraving settings for different materials for best results.
Leather laser engraving
Ever wonder how they designed a belt with such an intricate design? The answer is simple, with the help of a laser cutter. The precision of the laser engraver ensures that the laser does not move a millimeter from the designed path. So, the leather can be engraved or cut in almost any design you want.
In conclusion, leather is the best material for laser cutting and engraving. The organic molecules of the leather burn and evaporate under the action of the laser beam. So you can easily use any type of leather, including suede and nubuck. The problem is that you have to adjust the laser settings as needed to prevent damage to delicate surfaces.
Another thing to consider when laser engraving leather is the color and properties of the material. Synthetic leather is suitable for engraving and cutting. Likewise, light leather is great for engraving, while dark leather is only suitable for laser cutting. The darker leather hides the engraving, making all your hard work in vain. Therefore, before using laser engraved materials in your project, it is best to consult their suppliers.
Glass Laser Engraving
Glass is another commonly used item for laser engraving. The uniform glass surface is the perfect surface to imprint your design or laser cut name. This material is often used to customize wine bottles or to write names and quotes on mugs or mugs. However, there are several types of glass available on the market. Therefore, it is important to understand the properties of the material before placing it in the working area of the laser.
The first thing to consider is that flat glass is not the same as a curved cup. Again, you will need to use different laser settings and accessories to process this type of material. Flat glass plates are easy to engrave with CO2 lasers because of their uniform structure. The laser heat is perfectly distributed over the entire surface, resulting in a perfect finish. However, if you use too much laser power, you will experience some chipping and ruin the design.
Again, a curved glass, mug or mug is a whole different story. First, a typical laser does not engrave curved surfaces. For this, you have to use a laser engraver with a cylindrical working area. Additionally, the laser software for curved glass uses a WYSIWYG editor to do the job. Another way to prevent accidental damage is to cover the glass surface with a paper or towel to reduce the heat of the laser. However, make sure the covering is free of creases; otherwise, your final design won't be as perfect as you expect.
Acrylic Laser Engraving
Acrylic is a common replacement for glass and thick plastic sheets. This material is also known as polymethyl methacrylate (PMMA) or the name Plexiglass. Acrylic material is perfect for all laser projects including engraving and cutting. However, it is important to understand the properties of the material before choosing it.
Plexiglass is manufactured in two ways, casting and extrusion. Cast acrylic creates a frozen surface when engraved with a laser. Therefore, it is perfect for engraving some elegant designs and decorative items. On the other hand, the extruded PMMA is still clear even after engraving with a powerful laser engraver. Therefore, extruded PMMA is essential for laser cutting signs and banners.
One way to deal with acrylic is to mirror it in reverse. This process prints a reversed image on the transparent surface that looks normal on the back of the paper. This technique is widely used in branding and marketing. Therefore, mastering the art of laser engraving acrylic can be of great benefit to your business.
