Whether you are an efficient engineer or a beginner maker, learning the correct uses of design equipment in order to avoid pitfalls and mistakes needs time and experience. Every once in awhile, issues come up that leave designers wondering the things they did wrong or the way that they could do something better. This is true in almost any field and Laser Marking Machine Price engraving is no different.
Knowing how to avoid these mistakes so that they don’t come up again is half the battle. Bearing that in mind, let’s discuss five of the most common mistakes in terms of laser engraving and ways to avoid them in the future projects.
Mistake 1: Engraving Fabric nevertheless the Laser Burns through the Material – Step one 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 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 when the material can withstand it, increase the power before you obtain the results you are interested in.
With regards to direct-to-garment engraving, it really is useful to lower the dots per inch (DPI) at which you engrave. The larger the DPI, the better material will be removed. Engraving at 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 Generate a Frosty White Engraving – Most likely, this can be caused using the wrong acrylic inside the application. 2 kinds of acrylics are generally 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 type of acrylic is great for engraving since it turns a frosty white color when engraved, making it suitable for awards and plaques. It can be cut using a laser, however it won’t give projects flame-polished edges.
Another type of acrylic found in laser engraving is called extruded acrylic, which is formed into sheets by way of a machine. Extruded acrylic is normally more affordable than cast acrylic since it is formed via 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 alternatively a clear engraving. So ensure you are using cast acrylic if you want a frosted white finish.
Mistake 3: Inconsistent Glass Engraving – Oftentimes, each time a 500 Watt Laser Cutter strikes glass it can fracture the surface although not engrave deeply or remove the material needed to engrave fully. The fractured glass surface will create a frosted appearance, but could be rough and chipped depending on the kind of glass which is 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:
Utilize a lower resolution, about 300 DPI, that will generate a better result on glass when you separate the dots you are engraving.
Alter the black in your graphic to 80 % black. Run your laser engraver with Jarvis Dithering (this dithering pattern may be found in Epilog’s print driver), which will help to provide a smooth finish.
Sometimes, applying a thin, wet sheet of newspaper or even a paper towel for the engraving area may help with heat dissipation and enhance 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 towards the area you’re engraving – either together with your finger or perhaps a paper towel. Finally, if there are shards of glass after engraving, polish the location with a non-scratch scour pad.
Mistake 4: Wood Engraving Produces Different Results on the Same Setting – Wood is among the most laser-friendly materials available not only because it can be cut very easily, but in addition as it engraves very well. However, different woods have different reactions while they are laser engraved and provide different results. Lighter woods, like cherry or maple, create a nice contrast where laser burns away the wood, while denser woods require more Metal Engraver Marking Machine to reduce or engrave.
Grain density can transform dramatically depending on the type of wood you are working with. Cherry, alder, walnut and maple have fairly small veins of grain in them, while oak has medium to large veins. As an example, in case a large square pmupgg engraved into a bit of cherry, it would possess a uniform appearance; the location engraved will be smooth with little variation in height. However, if the same square was engraved into a piece of oak, its appearance would vary greatly in height and would have got a non-uniform appearance.
