If you are an accomplished engineer or a beginner maker, learning the appropriate uses of design equipment in order to avoid pitfalls and mistakes needs time and experience. From time to time, issues come up that leave designers wondering what they did wrong or the way that they could do something better. This is true in almost any field and Laser Marker Price engraving is no different.
Knowing how to prevent these mistakes therefore they don’t show up again is half the battle. Knowing that, let’s discuss five of the most common mistakes when it comes to laser engraving and the ways to avoid them in future projects.
Mistake 1: Engraving Fabric however the Laser Burns with the Material – The first step in avoiding burning fabric with a laser engraving/cutting machine is always to understand which fabrics can withstand this process 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 fabric can withstand it, boost the power up until you have the results you are searching for.
When it comes to direct-to-garment engraving, it is useful to lower the dots per inch (DPI) where you engrave. The higher the DPI, the more material will likely be removed. Engraving at a lower DPI helps guarantee the laser just slightly vaporizes the top 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 – Most likely, this is caused using the wrong acrylic in the application. Two types of acrylics are generally found in laser engraving and both are suitable for 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 sizes and shapes. This type of acrylic is great for engraving as it turns a frosty white color when engraved, which makes it appropriate for awards and plaques. It could be cut using a laser, nevertheless it won’t give projects flame-polished edges.
The other kind of acrylic utilized in laser engraving is called extruded acrylic, that is formed into sheets with a machine. Extruded acrylic is generally less expensive than cast acrylic since it is formed by way of a higher-volume manufacturing technique. However, it does react very differently with 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 make sure you are using cast acrylic if you want a frosted white finish.
Mistake 3: Inconsistent Glass Engraving – Oftentimes, each time a Metal Laser Sintering Machine strikes glass it can fracture the top although not engrave deeply or eliminate the material required to engrave fully. The fractured glass surface will generate a frosted appearance, but could be rough and chipped depending on the form of glass which is being engraved. As the frosted look is desired, nobody wants a rough surface or chipping.
To be able to create a smooth frosted finish, try incorporating one or several of the tips below:
Utilize a lower resolution, about 300 DPI, that will create a better result on glass while you separate the dots you happen to be engraving.
Modify the black in your graphic to 80 percent black. Run your laser engraver with Jarvis Dithering (this dithering pattern may be found in Epilog’s print driver), which will help to supply a smooth finish.
Sometimes, applying a thin, wet sheet of newspaper or even a paper towel to the engraving area can help with heat dissipation and improve the engraving process. Just make sure you will find no wrinkles within the paper after it really is applied. Another way to dissipate heat is to apply a thin coat of liquid dish soap to the area you’re engraving – either along with your finger or even a paper towel. Finally, if there are 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 probably the most laser-friendly materials available not merely because it could be cut very easily, but in addition because it engraves adequately. However, different woods have different reactions when they are laser engraved and produce different results. Lighter woods, like cherry or maple, create a nice contrast where the laser burns away the wood, while denser woods require more Printer Machine Code 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 inside them, while oak has medium to large veins. As an example, if a large square pmupgg engraved into a bit of cherry, it would have got a uniform appearance; the area engraved will be smooth with little variation in height. However, if the same square was engraved into a bit of oak, its appearance would vary greatly in height and would have a very non-uniform appearance.
