Whether you are an accomplished engineer or a inexperienced maker, learning the correct uses of design equipment in order to avoid pitfalls and mistakes will take time and experience. Every once in awhile, issues appear 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 Rust Removal Service engraving is no different.
Knowing how to prevent these mistakes so that they don’t show up again is half the battle. Knowing that, let’s discuss five of the most common mistakes with regards to laser engraving and the ways to prevent them later on projects.
Mistake 1: Engraving Fabric nevertheless the Laser Burns through the Material – The first step in avoiding burning fabric with a laser engraving/cutting machine is to understand which fabrics can withstand the procedure and at what temperatures. Heartier fabrics like denim, canvas and leather can withstand higher power settings during engraving. But in terms of 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 if the material can withstand it, increase the power until you obtain the results you are interested in.
In terms of direct-to-garment engraving, it really is helpful to lower the dots per inch (DPI) where you engrave. The higher the DPI, the greater material will be removed. Engraving at a lower DPI helps make sure the laser just slightly vaporizes the very best layer and doesn’t burn entirely from the fabric. Most fabric engravings do fine at 150 to 300 DPI.
Mistake 2: Acrylic Doesn’t Create a Frosty White Engraving – More than likely, this really is caused by using the wrong acrylic in the application. 2 kinds of acrylics are usually utilized in laser engraving and both are suitable for different applications. Cast acrylic sheets and objects are produced from a liquid acrylic that is certainly poured into molds that can then be set into various styles and sizes. This sort of acrylic is perfect for engraving as it turns a frosty white color when engraved, rendering it ideal for awards and plaques. It may be cut using a laser, however it won’t give projects flame-polished edges.
One other form of acrylic used in laser engraving is called extruded acrylic, that is formed into sheets by a machine. Extruded acrylic is generally less expensive than cast acrylic as it is formed via a higher-volume manufacturing technique. However, it can react very differently with the laser engraving machine. This kind of acrylic cuts cleanly and smoothly and produces a flame-polished edge; however, when engraved, it doesn’t produce that frosted look, but instead a clear engraving. So ensure you are using cast acrylic if you want a frosted white finish.
Mistake 3: Inconsistent Glass Engraving – Oftentimes, whenever a Fiber Laser Marking With Rotary strikes glass it will fracture the outer lining although not engrave deeply or remove the material necessary to engrave fully. The fractured glass surface will produce a frosted appearance, but may be rough and chipped depending on the form of glass that is certainly being engraved. As the frosted look is desired, nobody wants a rough surface or chipping.
In order to produce a smooth frosted finish, try incorporating one or a lot of the tips below:
Use a lower resolution, about 300 DPI, that will generate a better result on glass while you separate the dots you might be engraving.
Change the black within your graphic to 80 percent black. Run your laser engraver with Jarvis Dithering (this dithering pattern can be found in Epilog’s print driver), which can help to supply a smooth finish.
Sometimes, applying a thin, wet sheet of newspaper or a paper towel to the engraving area may help with heat dissipation and increase the engraving process. Just make sure you will find no wrinkles inside the paper after it is applied. Another way to dissipate heat is to use a thin coat of liquid dish soap for the area you’re engraving – either with your finger or even a paper towel. Finally, if you will find shards of glass after engraving, polish the area 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 may be cut quickly, but additionally as it engraves perfectly. However, different woods have different reactions while they are laser engraved and produce different results. Lighter woods, like cherry or maple, create a nice contrast in which the laser burns away the wood, while denser woods require more Laser Machines For Engraving to reduce or engrave.
Grain density may change dramatically depending on the form of wood you are utilizing. Cherry, alder, walnut and maple have fairly small veins of grain within them, while oak has medium to large veins. As an example, in case a large square pmupgg engraved into a piece of cherry, it could possess a uniform appearance; the area 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.
