Whether you are an efficient engineer or a beginner maker, learning the correct uses of design equipment in order to avoid pitfalls and mistakes takes time and experience. From time to time, issues appear that leave designers wondering the things they did wrong or the way that 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 so they don’t appear again is half the battle. Knowing that, let’s talk about five of the very common mistakes in terms of laser engraving and ways to avoid them later on projects.
Mistake 1: Engraving Fabric nevertheless the Laser Burns through the Material – The initial step in avoiding burning fabric with a laser engraving/cutting machine is always to understand which fabrics can withstand the procedure 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 essential 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 when the fabric can withstand it, raise the power until you obtain the results you are looking for.
In terms of direct-to-garment engraving, it really is beneficial to lower the dots per inch (DPI) in which you engrave. The greater the DPI, the better material will likely be removed. Engraving in a lower DPI helps ensure the laser just slightly vaporizes the very best layer and doesn’t burn entirely through the fabric. Most fabric engravings do fine at 150 to 300 DPI.
Mistake 2: Acrylic Doesn’t Produce a Frosty White Engraving – Probably, this is caused by using the wrong acrylic in the application. Two kinds of acrylics are typically found in laser engraving and both are suitable for different applications. Cast acrylic sheets and objects are made from a liquid acrylic that is poured into molds that will then be set into various sizes and shapes. This kind of acrylic is great for engraving as it turns a frosty white color when engraved, which makes it suitable for awards and plaques. It may be cut having a laser, but it won’t give projects flame-polished edges.
One other kind of acrylic used in laser engraving is called extruded acrylic, that is formed into sheets by way of a machine. Extruded acrylic is usually more affordable than cast acrylic since it is formed via a higher-volume manufacturing technique. However, it can react very differently with the laser engraving machine. This type of acrylic cuts cleanly and smoothly and produces a flame-polished edge; however, when engraved, it doesn’t produce that frosted look, but rather a precise engraving. So make sure you are using cast acrylic if you want a frosted white finish.
Mistake 3: Inconsistent Glass Engraving – Oftentimes, when a Fiber Laser Cleaner strikes glass it can fracture the top although not engrave deeply or remove the material needed to engrave fully. The fractured glass surface will create a frosted appearance, but can be rough and chipped depending on the kind of glass that is certainly being engraved. As the frosted look is desired, no one wants a rough surface or chipping.
In order to produce a smooth frosted finish, try incorporating one or some of the tips below:
Use a lower resolution, about 300 DPI, that will create a better result on glass as you separate the dots you might be 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), that will help to supply a smooth finish.
Sometimes, applying a thin, wet sheet of newspaper or a paper towel to the engraving area can help with heat dissipation and enhance the engraving process. Just be sure you will find no wrinkles inside the paper after it is actually applied. Another way to dissipate heat is to apply a thin coat of liquid dish soap for the area you’re engraving – either along with your finger or a paper towel. Finally, if you will find shards of glass after engraving, polish the region having a non-scratch scour pad.
Mistake 4: Wood Engraving Produces Different Results on the Same Setting – Wood is probably the most laser-friendly materials available not merely because it could be cut effortlessly, but in addition since it engraves very well. However, different woods have different reactions when they are laser engraved and provide 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 Laser Rust Removal Price to reduce or engrave.
Grain density can change dramatically depending on the kind of wood you happen to be working with. Cherry, alder, walnut and maple have fairly small veins of grain inside them, while oak has medium to large veins. For example, in case a large square pmupgg engraved into some cherry, it might possess a uniform appearance; the location engraved could be smooth with little variation in height. However, when the same square was engraved into some oak, its appearance would vary greatly in height and would possess a non-uniform appearance.
