Each material Needs Different Settings During Laser Engraving

Each material Needs Different Settings During Laser Engraving

For laser engraving and etching, the right engraving equipment is capable of handling a wide range of materials ranging from wood, acrylic to plastic and beyond. These materials need different kinds of settings that you need to understand to get the expected results in the shortest time possible.

What determines the Speed and Power Settings?

The speed and power settings that you choose depends upon the material that you wish to handle and the wattage of the machine you will be using for the task. For instance, the higher the wattage, the faster the speed you can achieve and the deeper the engraving depth.  Materials that need lower wattage such as acrylic need the equipment’s wattage to be adjustable to achieve the right settings.

You adjust the settings of the equipment depending on the material. You will work with wood, acrylic, plastic, metal and other materials. With each material, you will get the best results if you have the right laser equipment for the task. Check Needham-coding.com for the right equipment. Here are the various materials and the settings to use.

Wood

Wood represents the most common material for engraving by far. It takes the laser beam quickly and easily. You can engrave and cut it easily. When you engrave it, light-colored wood produces the best contrast especially in places where the laser has burnt away the wood.

The best thing about wood is that it comes in different types, each with its characteristics. Some types are denser than others while others are lighter in color compared to others. You can achieve a great depth when engraving wood as compared to other materials. The only downside is that it will take you more power than other lighter materials.

When engraving wood, it is wise to put the power at 100 percent but adjust the speed of the laser to achieve the depth you desire. Wood takes a wide range of designs ranging from grayscale to clipart images.

Acrylic

This is the second best material to work with next to the wood. It is easy to cut and engrave using the laser. You can also get acrylic in a wide variety of sizes and shapes. It is also cheaper than most materials, making it ideal for your projects.

The approach to engraving acrylic is slightly different from other materials. You will have to engrave the design on the back of the surface so that you produce a see-through effect. Set the equipment at low power and high speed for this purpose. A little power is all that you need to achieve the design you seek. If you put too much power, you stand to distort the acrylic.

If you get a surface that has already been painted, you can engrave the design through the paint into the acrylic for a great effect. Don’t apply a lot of power because it will melt the paint, leading to a distorted design.

Glass

Glass gives a classic and sophisticated look when engraved the right way. Laser works by fracturing the glass surface, giving a frosted look that is a darling to many people. However, you need to handle glass carefully; otherwise it will chip and flake leading to an undesirable look. You need to protect the surface of the glass while engraving it.

The Bottom-line

Different surfaces meant for engraving or etching need different settings to achieve the perfect results. Make sure you understand the material for etching and the results you wish to achieve. Once you know the material, you need to come up with the perfect settings to give you what you want. In all these materials, the right kind of laser equipment will give you the best results.
