Epilog has a range of offerings in their lineup, including the Zing Laser Starter Series, the Fusion Pro 24 and 36, and the Fusion Pro 48. Each of these high-end machines boasts the latest in laser technology to deliver a level of quality and performance that is unrivaled in the industry.
The Fusion Pro 24 is a 24" x 24" machine, boasting 165 IPS engraving speeds. This is the equivalent of 4.2m/s in real world terms. It also features Epilog's IRIS Camera Positioning system, which allows users to see a graphical representation of their current working space in real time. In addition, the machine features a 4.0" lens that is capable of delivering a focused beam over a larger vertical distance.
The Fusion Pro 3Jaw Chuck is a cool feature of the machine that enables the mechanical clamping of cylinders or odd shaped items. This allows for improved air circulation and reduces backside burning.
The Fusion Pro 24 is not the only Epilog model to feature the new IRIS Camera Positioning system. Additionally, the Fusion Pro 48 is able to achieve 5G acceleration, which is an impressive feat.
There are a few things to consider when shopping for a laser engraver, but in the end, the only decision you will need to make is what size of machine to purchase. With options ranging from the compact and cost effective to the full blown, powerful and expensive, your choice will depend on how much your business will be willing to spend.
Aside from the actual laser machining process, there are other factors that determine the size and shape of patterns generated with laser beams. Specifically, these factors involve the location and length of the beam spot, the type of material being etched, and the scan speed.
The effect of these factors on the overall pattern is known as the thermo-mechanical model. The model predicts the linear relationship between laser power and melt pool depth. It also considers the multi-track and multi-layer effects. This model has been validated by comparing its predictions to experimental data.
Another important aspect to consider is the type of hatch pattern. These patterns range from the basic single line to the elaborate cross-hatched arrangement. In the latter case, each track represents a different laser path. Moreover, the amount of overlap between tracks is important in avoiding porosity of the build.
One interesting feature of the cross-hatched pattern is the separation of the adjacent peaks. This may be as small as 0.5 mei or as large as 100 mei.
Another important aspect of the multi-track and multi-layer effects is the total number of tracks on the layer. The number of tracks varies depending on the rotational angle. Increasing the scan speed will reduce the length of the first several paths at the layer.
The temperature change associated with the laser scanning process is also important. Specifically, the difference in thermal properties at the turn points of the scan will influence the next laser step. As the laser scans, the heat emitted by the laser is transferred to the material and eventually deposited in the form of a deep pool.
Compared with a single-directional scan, a bi-directional scan can lead to a deeper melt pool and greater yield strength. Nevertheless, it does not guarantee a smooth surface.
Vector engraving and raster etching on laser etching machines are two different types of processing. They have distinct uses and require different parameters. A good understanding of the two processes will help you choose the right machine for your project.
Vector images are composed of lines and points, but raster images are made up of pixels. Each pixel is assigned a color value. Laser engravers follow the pattern of these pixels to engrave an image.
Raster etching on laser etching machines involves a laser sweeping back and forth across a surface. The image is then engraved by the machine using a line-by-line process.
Because of the way the laser works, a raster engraving may not cut through the material. However, a raster engraving may leave an outline appearance on the part. It is also easier for laser cutters to work with.
On the other hand, vector etching is a fast method for engraving shapes. Line-by-line operations create bold engravings.
Raster images can take a long time to produce. This can make it difficult to work with intricate images. In addition, raster files are often in a bi-directional format. Therefore, combining the two techniques requires separate files.
Both methods can produce high-quality results. With vector etching, you can achieve high accuracy and detail. For example, an intricate design can be etched onto a wood piece, whereas a raster engraving may leave an open-ended area.
Laser etching can be used on a wide variety of materials. Wood is a common substrate for this type of engraving, but it is important to note that wood has specific characteristics. While the wood itself is not harmed by laser etching, sap can come out of the wood's fibers. If the sap does come out, the surface of the engraved area can be degraded.
If you're looking to mark metal, a fiber laser engraving machine may be your best option. These powerful machines can cut at speed and engrave on a variety of metals and materials. But beware: these devices aren't cheap. So make sure you find a high-quality machine that can meet your needs.
To engrave on metals, you'll need a laser that can produce an intense beam of light. Fiber lasers are effective on a wide range of metals and can be used for jewelry, bar codes and more. They also offer greater detail than generic CO2 lasers.
Unlike other types of lasers, a fiber laser is safe to use and has a relatively small focal point. It can cut materials up to six times faster than CO2 lasers. And because it doesn't require any coatings, it's a great choice for hobby projects.
Depending on what you're marking, you can choose a laser source that offers 25 to 150 watts. In addition to cutting and engraving, a fiber machine can also help preserve the working environment.
If you need a large work area, you can purchase an xTool. The xTool D1 Pro (20W) is a powerful laser engraver that can engrave on a lot of material. This machine has a wide range of features, including an automatic XY axis and a backlit marking table. You can even connect the xTool via an iPad or similar device.
Another option is the LS100EX Fiber machine. This is a powerful tool that uses Intelligent Quotient to provide better processing results. Also, its auto focus feature makes it easier to use. Moreover, this machine has a red pointer beam and backlit marking table.
Laser etching is a chemical process that changes the topmost surface layer of glass. It is also capable of creating intricate patterns without shattering the glass.
For optimal results, the images should be optimized to at least 80% grayscale. This is a nice trick, because a grayscale matrix will help you choose the appropriate settings for your laser etching machine.
Another way to optimize the images is to use curves. A curves tool is a nice trick to make middle grey tones lighter or darker. However, experimenting with the curves tool can result in some strange results.
While there are numerous techniques to maximize the benefits of the laser, there are some basic settings to keep in mind. These include the proper spacing of the lines and the correct laser irradiation count. If you want to ensure a deep engraved impression, increase the irradiation count.
Optimizing the images for laser etching machines also means choosing the right type of lens. The ideal lens for etching glass is a 2" lens. You can also consider using a wide angle lens if the item is thick or difficult to handle.
For the best results, make sure your work platform is well-covered. A paper cover will help you keep your work area clean. Also, a uniform coat of black paint can be useful.
As with any engraving procedure, you should also try to minimize the chance of unwanted fractures. In addition to the recommended line spacing, you can protect the glass from unnecessary fracturing with a few drops of liquid soap.
