Whether you are an accomplished engineer or a beginner maker, learning the proper uses of design equipment to avoid pitfalls and mistakes takes time and experience. Every now and then, issues come up that leave designers wondering the things they did wrong or the way they could do something better. This is true in every field and Laser Marking Machine China engraving is no different.

Knowing how to avoid these mistakes therefore they don’t show up again is half the battle. With that in mind, let’s discuss five of the most common mistakes in terms of laser engraving and ways to avoid them later on projects.

Mistake 1: Engraving Fabric however the Laser Burns from the Material – The first step in avoiding burning fabric using a laser engraving/cutting machine is to understand which fabrics can withstand the process as well as at what temperatures. Heartier fabrics such as denim, canvas and leather can withstand higher power settings during engraving. But with regards to delicate fabrics, it is important to start your settings at high speed (near or at 100%) and low power (around 5% to 10%). Test these initial settings on some spare material, and in case the fabric can withstand it, raise the power up until you obtain the results you are searching for.

In terms of direct-to-garment engraving, it is helpful to lower the dots per inch (DPI) in which you engrave. The greater the DPI, the better material will be removed. Engraving in a lower DPI helps guarantee the laser just slightly vaporizes the top layer and doesn’t burn entirely with the fabric. Most fabric engravings do fine at 150 to 300 DPI.

Mistake 2: Acrylic Doesn’t Generate a Frosty White Engraving – Most likely, this is caused by using the wrong acrylic in the application. Two types of acrylics are generally utilized in laser engraving and both are compatible with different applications. Cast acrylic sheets and objects are made of a liquid acrylic which is poured into molds that may then be set into various shapes and sizes. This sort of acrylic is perfect for engraving because it turns a frosty white color when engraved, which makes it ideal for awards and plaques. It could be cut with a laser, however it won’t give projects flame-polished edges.

One other kind of acrylic used in laser engraving is known as extruded acrylic, which is formed into sheets by a machine. Extruded acrylic is usually cheaper than cast acrylic since it is formed by way of a higher-volume manufacturing technique. However, it will react very differently with all the laser engraving machine. This kind of acrylic cuts cleanly and smoothly and generates a flame-polished edge; however, when engraved, it doesn’t produce that frosted look, but rather a precise engraving. So ensure you are using cast acrylic if you prefer a frosted white finish.

Mistake 3: Inconsistent Glass Engraving – Oftentimes, when a Stainless Steel Fiber Laser Marking strikes glass it is going to fracture the surface but not engrave deeply or eliminate the material necessary to engrave fully. The fractured glass surface will generate a frosted appearance, but can be rough and chipped depending on the kind of glass that is being engraved. Whilst the frosted look is desired, nobody wants a rough surface or chipping.

To be able to generate a smooth frosted finish, try incorporating one or several of the tips below:

Utilize a lower resolution, about 300 DPI, which will create a better result on glass as you separate the dots you are engraving.

Change the black within your graphic to eighty percent black. Run your laser engraver with Jarvis Dithering (this dithering pattern may be found in Epilog’s print driver), which can help to provide a smooth finish.

Sometimes, applying a thin, wet sheet of newspaper or perhaps a paper towel towards the engraving area may help with heat dissipation and enhance the engraving process. Just make sure there are no wrinkles in the paper after it is applied. An additional way to dissipate heat is to apply a thin coat of liquid dish soap to the area you’re engraving – either with your finger or a paper towel. Finally, if you will find shards of glass after engraving, polish the region with a non-scratch scour pad.

Mistake 4: Wood Engraving Produces Different Results on the Same Setting – Wood is one of the most laser-friendly materials available not only because it can be cut quickly, but in addition because it engraves adequately. However, different woods have different reactions when they are laser engraved and create different results. Lighter woods, like cherry or maple, produce a nice contrast in which the laser burns away the wood, while denser woods require more Low Price Laser to cut or engrave.

Grain density may change dramatically depending on the type of wood you are dealing with. Cherry, alder, walnut and maple have fairly small veins of grain inside them, while oak has medium to large veins. As an example, when a large square pmupgg engraved into some cherry, it would have a very uniform appearance; the location engraved will be smooth with little variation in height. However, if the same square was engraved into some oak, its appearance would vary greatly in height and would have got a non-uniform appearance.
