Some people hate Fords and swear up and down that they’ll never drive another Ford for the rest of their lives. There are other people who love Fords and swear up and down that they’ll never drive anything else, while pointing out how much they despise Chevrolet or Honda or some other manufacturer.

Why? They’re all cars. How different can they be?

Depending on who you ask, the answers could range from a casual, “not much” to an emphatic, “completely!”

However, of all the people you could ask, the manufacturers—the people who design and build and fix the cars—are likely to provide the most detailed responses. They can tell you precisely how they are different and how they are unique.

That is the purpose of the Laser Compendium: to present our A&E readers with a collection of information from the laser manufacturers providing details each feels are unique.

So, take a look at the information the industry’s top laser suppliers provided A&E in the next few pages, and read to determine which unique laser best fits your unique business.

GRAVOGRAPH

There are a number of things which make Gravograph’s lasers unique. The Gravograph LS Laser Engraving line was designed and manufactured with the end user in mind. Great care was taken to make the various systems user friendly, versatile, reliable, and most importantly, a tool that will increase productivity in the workplace. We have developed a laser offering that can be tailored to specific needs of the customer. The LS lasers come in three engraving field sizes. The compact LS700 has a 12” x 12” engraving area. The versatile LS800 offers a 12” x 24” field size, and the heavy duty LS900 has a standard field size of 24” x 24”. The table sizes were carefully chosen to coincide with flat stock material sizes, considered “standard” in the market. Utilizing standard size material minimizes pre-cutting and more importantly helps to eliminate material waste. Gravograph offers a range of laser powers that should meet most, if not all, applications requirements. The LS700 starts at the economical range of 10 watts and can be purchased in both 20watt and 30watt variations. The LS800 and LS900 come in the following ranges: 30watt, 40watt, 60watt and 80watt.

The Gravograph laser systems have many standard features that aid in efficient use of the system and greatly benefit productivity:

The Graphical User Interface Software (or GravoStyle 5) is the first package ever developed to address the specific needs of marking and engraving customers. What is unique is that the G5 software actually has the capacity to drive all of our laser units and most of our rotary units. Imagine the time advantage in only having to learn one software package in conjunction will multiple marking devices.

Auto Focus Probe provides very quick set-up, to adjust to differing height parts and varying engraving planes. Utilizing the auto focus feature dramatically reduces the time it takes to set up between jobs.

The LS800 and LS900 systems are equipped, standard, with a unique Dual Function Exhaust Capability. Using a simple, manually adjustable slider valve, the operator can set the exhaust flow to evacuate the entire lasing cabinet or divert it to a localized exhaust port on the head of the XY gantry.

As a set-up tool, all Gravograph lasers include a Visible Red Pointer that allows the operator dry run capabilities. The job can be run with just the red light on, so proper alignment of the process can be assured, without wasting material.

The systems are also plumbed to deliver the Air Assist directly in the lasing area to aid in processing certain materials. This feature is manually adjustable, but programmable in actuation. The operator simply needs to attach a compressor to the outside port.

UNIVERSAL LASER SYSTEMS

Universal Laser Systems is a leading pioneer of computer-controlled laser engraving and cutting technology. Holding multiple patents in laser technology, part of what makes ULS unique is the fact that we are an engineering-based company that responds to our customers’ needs through innovation and long-term commitment to research and development. Our large engineering team includes electrical and mechanical engineers, scientists with expertise in lasers and optics, software developers and strong sales and technical support teams. Furthermore, ULS provides global sales support with a large and vast external representative base that is unlike that of any other laser system company.

The technical and engineering strengths at ULS cultivate an innovative atmosphere that contributes to our reputation as a leader in laser technology. The growing need for new technology was the impetus for investing major resources in the development of CO2 lasers. ULS began manufacturing our own CO2 lasers that are used inside the laser systems in the mid-1990s because the limitations imposed on us by other manufacturers inhibited our ability to develop new technology (i.e. we wanted to build smaller systems with higher, air-cooled laser power).

Specifically designed for the engraving industry, the CO2 lasers manufactured by ULS are optimized for our own laser engraving systems. We were awarded multiple patents in laser technology, specifically for the design of the CO2 lasers in our systems. The laser systems can be easily upgraded with Quick Change Laser Cartridges using Permalign™ technology (no tools required). Not only are the lasers used in ULS laser engraving systems, but they are also sold to other companies who integrate them into their manufacturing systems. In fact, thousands of CO2 lasers are sold every year throughout the world.

In addition to manufacturing CO2 lasers, ULS is the only laser system manufacturer that provides a patented configuration approach that allows customers to select the platform, laser cartridge or multiple cartridges and accessories to ensure their specific application needs are met. From the compact, easy to use and affordable VersaLaser to the new industrial XL Series, ULS offers a broad range of products to suit every customer’s needs. Table sizes on ULS systems range from 16”x12” to 48”x24” with laser power up to 300 watts. With our Quick Change Laser Cartridges™ and Rapid Reconfiguration Capability™, customers can easily upgrade to a larger system, keeping their current CO2 laser, or use one or two lasers to optimize their laser systems’ performance based on production needs.

The fundamental difference between Universal Laser Systems and our competitors is that we are both laser and laser system technology innovators while other companies are integrators. We design components to provide the most effective solutions to challenging engineering issues. From the CO2 laser and optics to the motion system and print driver software, ULS builds the optimum system from the ground up to meet our customers’ needs.

If a part isn’t available, we will make it ourselves. For example, customers demanded an inexpensive solution to mark metal that didn’t require a YAG laser or the use of metal marking compounds, like Cerdec. ULS designed special optics called High Power Density Focusing Optics (HPDFO). HPDFO produces a smaller, focused beam “spot” than a standard laser beam delivery optical system. HPDFO increases the power density of the laser to achieve the effects of a laser that has much higher power. Customers can now mark some uncoated metals, such as stainless steel, without the need for chemicals or coatings using their current CO2 laser system from Universal (Professional and XL Series only).

Universal Laser Systems continues to develop the newest technology to address real needs of customers in our industry. We are not dependent on off-the-shelf products. Our in-house system and software design teams ensure immediate response to customer needs, and our strong OEM business is a testimonial to the quality of our CO2 lasers. ULS continuously updates its product line through relentless devotion to research and development and innovation. Multiple patents issued to ULS attest to this fact. Our focus is on long-term R&D and technology improvements to continue to provide the best solutions for this market.

TROTEC

Trotec likes to divide the issues that differentiate our systems from all others into two categories. The first is design and construction, and the second is our software concept.

Design & Construction

From the beginning, we took the approach of designing and building the highest-quality, top-performing products in the class. Rather than searching for ways to cut costs, we have selected components for their performance and reliability.

Some of the differences are immediately evident, such as the overall construction of the chassis. The fit, finish and rugged construction of the cabinet are also immediately evident. They are critical to maintaining a flat work surface with consistent focal length and provide the foundation for our high-performance motion systems. Other differences include a modular design of components for easy replacement, if required, and attention to small details, such as the dual halogen lamps that illuminate the work area. Our Speedy II systems weigh more than 350 lbs.

Most of the technology in Trotec laser systems is hidden from view in order to protect sensitive components from contamination. We call this approach In-Pack Technology™. It includes protection of the motion system, optics, motors and electronics. Our motion system uses brushless servo motors with optical encoders, high-speed, stainless steel linear bearings and a patented drive-belt design that has embedded steel cords for maintenance free operation and a long useful life.

The work table is constructed of two sheets of stainless steel formed around a plastic core and glued under pressure on a granite block to make it as flat as possible. The table is driven by three lead screws. The result is the flattest work area for consistent focal length.

The overall result is incredibly fast engraving, 140ips (inches per second) at 5Gs of acceleration, with excellent results on text as small as 3-point type.

Also, our systems include a beam expander as a standard feature—an expensive option from some companies—permitting limited direct engraving on metals.

Software Concept

At Trotec, we looked at the limitations of sending jobs directly from the design software to the laser the way printers and plotters operate. These include problems with onboard memory and limited control over operating parameters. We decided to take an approach that is unique in the industry and clearly sets our systems apart. We make it easy to set up jobs and therefore make the systems more productive.

Trotec has developed a sophisticated printer driver that we call JobControl™. With this approach, jobs reside in the memory of the host computer. This means that there are never limitations to the size of the job or the number of jobs that can be processed.

The concept includes constant high-speed, bi-directional communication between the laser and the computer. Rather than use a small LED display to control engraving parameters, we can use the PC monitor to provide more functionality in an easier to access format. This approach also allows us to provide functionality that is not available on competitive systems including the following:

1. Material Database Template: Provides a database of parameter settings for different materials including settings for unique jobs.

2. Job Database: Every job can be saved, ready to be engraved without going back to the design software. The laser settings can be linked to the job for quick setup of jobs that are repeated periodically.

3. Multiple Job Engraving: Multiple jobs can be engraved without the need to batch them in the design software.

4. Control over speed, power, pulsing, frequency, multiple passes and computer control of air assist.

5. Because of the bi-directional communication between the PC and the laser, it is easy to position artwork or text in unusual locations. This process can be completed in a fraction of the time required by systems without this capability.

EPILOG LASER

Epilog creates lasers whose unique qualities can be established point by point.

Standard Features — The standard features of our systems are unrivaled for quality and functionality. We equip all Epilog laser systems with Auto Focus, Red Diode Pointer and Air Assist as standard equipment. The Epilog Mini includes an additional Integrated Vector Grid and Vacuum Table.

Auto Focus — Epilog integrates as standard equipment our exclusive magneto-mechanic Auto Focus device, which provides for extremely accurate focusing over the entire engraving and cutting surface. Epilog’s Auto Focus works with our Rotary Attachment, and even works on transmissive materials such as glass or acrylic.

Servo Motors — Epilog exclusively uses servo motors to power the X and Y axis of our laser engraving systems. Our closed-loop servo motors provide superior speed (ramp down and acceleration) and intelligent “feedback” (position sensing) which results in overall higher quality in the final engraving. Epilog servo driven systems will improve productivity between 15% and 50% over stepper motor driven systems, depending on the type of application. Typefaces of 2.5 points in size are not a challenge for our laser systems.

Laser Tubes — The laser tube is the heart of the system. That’s why Epilog uses Coherent/DEOS waveguide laser tubes in all of our models. DEOS has been manufacturing sealed carbon dioxide laser tubes for more than 20 years and was a large supplier to the military for more than 15 years. They rate their tubes for 25,000 – 30,000 hours of running before needing a recharge.

The laser tubes used in all Epilog systems are rated to operate at their minimum rated wattage output whether they have been on for three minutes, three days or three months. The laser beam quality and diffusion tolerances Epilog adheres to are the most stringent available.

Optics System — Unlike systems that cover their lenses and require tools for access and cleaning, Epilog’s Crystal Clear Optics are designed for easy maintenance. Ease of inspecting and cleaning protects the optics and provides consistent beam quality without the worry of expensive replacement. This also allows for simple and easy lens changes (1.5”, 2.5” and 4” available only on the larger EX systems) with absolutely no change to the beam alignment necessary.

NeverWear Bearings —  Epilog’s NeverWear bearings are a two-part rail/bearing structure that incorporates a stainless steel rail and slide unit containing 64 stainless steel ball bearings. These bearings are commonly known as Linear Guides or Linear Way bearings. The design of the NeverWear bearings system is so robust that with periodic cleaning and lubrication, they should last for the life of your machine without replacement.

Internal Ethernet card —All current Epilog systems include an internal Ethernet network card allowing the system to have its own IP address and to run from any PC on a network.

Modular components —  Not only is the laser tube a “quick change” module, but so are the other major components: power supply, mother board, user interface, X-axis assembly (houses mirrors 2 & 3). All of these modules can be replaced in less than 15 minutes on Epilog’s laser systems.

Windows-style LED display — The LEGEND EX laser systems have a 4 x 3 inch Accu-View windows-style LED display. The LED display has pull-down menus to allow control of laser settings, job selection, diagnostics, and graphical displays of jobs currently stored in memory.

Steel Construction — The Epilog LEGEND EX lasers are constructed of steel sheeting, fabricated for maximum strength. The NeverWear bearings are also made of stainless steel, machined to precise tolerances for a long and lasting life.

Technical Support —  Epilog’s technical support staff is available from 6:00am to 6:00pm Mountain Time to answer your operational questions, perform problem isolation and diagnosis, coordinate overnight parts shipping and discuss other related topics.

True 1,200 DPI Resolution —  Epilog’s laser systems feature 1,200 dpi (maximum) resolution. Overall, Epilog uses the highest quality, longest lasting, precision components to give you the capability to deliver only the highest quality products.

Experienced Distributors —  Our distributors include some of the industry’s most knowledgeable representatives, having been with the company for many years. Their knowledge and experience helps our customers find the best laser systems to meet their needs.

Engraving Quality —  Epilog developed the first small format laser system, and has been improving our systems every year since 1988 to offer you the best engraving quality available. Our combination of servo motors, linear encoders, and high-precision components allows us to provide the deepest, darkest, highest-quality engraving available.

History —  Epilog was incorporated in 1988 and started engineering the first open-architecture laser engraver capable of running on any Windows-based graphic design software. Epilog holds several patents associated with laser engraving and was the first to offer rubber stamp software for laser engraving, raster engraving, motorized Z-axis table, auto focus and many more features. It’s this combination of experience and innovation that allows us to continue to produce laser systems that stand out in the industry.

VISION

The Vision VXL Series Laser was the first high-speed laser system of its kind developed for the personalization marketplace. These galvo-based laser systems have the ability to provide laser marking at a rate of five to fifty times faster than traditional laser systems.

The system utilizes its own VXL Series Laser Software, which imports files from almost any graphics package. With an XY table for loading parts in volume, this is your ultimate production tool. The Vision VXL series can also be adapted to your assembly line for added efficiency. Class I or Class IV solutions are available in 10-300 watts.

The VXL Series Laser is well-suited for use on wood plaques, plastic laminates, acrylic, anodized aluminum, brass, personalized pens (1 pen per second), paper, leather, textiles, stone, marble, glass and many others. In addition, it lends itself well for use in automated assembly line production applications.

Vision Miro II™ YAG Galvo Systems

With the same galvo speed, these YAG-based lasers are the choice for marking all types of metal. Two or three axis models are offered. A rotary carousel or x-y table is available for feeding parts.

Production Configurations

Vision offers both YAG and CO2 lasers that have the ability to be used as independent workstations or as an integrated part of a production line. The laser systems are self-contained with the electronics (inside the main rail), the laser source, the galvo head and the cooling system. The typical freestanding production configuration may include an industrial PC with LCD monitor, a Class 1 enclosure and a parts-feeding mechanism, such as an X-Y positioning table or carousel-type feeder.

XENETECH

Xenetech laser systems have many features that make them unique in the market. By listening to our customers, we have identified their laser production needs and addressed them. At Xenetech, we feel that our system offers potential customers the complete laser package needed for them to be successful.

We have several features that make our systems easy to use. The 32-Bit Xenetech Laser Print Driver allows customers to run from their current Windowsâ„¢ software. This driver has user-friendly graphics that make it easy to navigate and use. The touch screen on the laser is menu driven, and it allows the customer to access all features without needing to scroll through unrelated features. Since all the options on the touch screen are software driven, new features can be updated by simply updating the firmware on the laser system.

Our automatic focus can be controlled from the laser touch screen, the laser print driver, or the Xenetech Graphic Workstation software (XGW). The system can focus on a specific point assigned from XGW, or focus on the point created by the red diode pointer. Next, up to four home positions can be saved and accessed from the laser touch screen. These home positions contain the X, Y and Z locations for customer pieces or fixtures placed on the laser work area. We also include a blower relay with our laser systems, so the blower attached to the laser can be automatically turned on at the beginning of the job and turned off at the end of the job. A one to thirty second blower delay can be set to keep the blower running at the end of the job and allow the laser cabinet to be properly evacuated of all fumes. Our focus-offset feature can be used for different focal length lenses, or it can be used to place material slightly out of focus for better laser engraving or cutting effect.

Several features make Xenetech systems very productive and unique from our competitors. We have a maximum raster engraving speed of up to 150 inches per second, and we can also run our systems at a very slow vector cutting speed of .01 inches per second. This type of speed control allows end users to cut a greater variety of materials at greater thickness or higher rate.

The Xenetech Graphic Workstation Software was made to increase engraving production for our customers. Multiple plate layouts with variable text are easily created in this software. Three different types of automatic grid cut out types are available for multiple plate jobs. Xenetech jobs can also be set to raster engrave from the bottom up or top down. In addition, four different origins can be referenced from the XGW software. This feature allows the operator to reference the center of the engraving area, which is very helpful when laser marking a round or cylindrical item.

Jobs are downloaded to our systems via an Ethernet connection. This connection allows the laser system to be accessible by any computer on the local network, and its only limit to job memory is the size of the hard drive on the network computer. For example, jobs can be created by a design department and placed in a network folder to be recalled by the operator using the laser touch screen. Our systems come with a report program that allows engraving managers to track the engraving times of jobs run during the day, week or month.

Xenetech’s polymer bearings require no lubricant. Our systems have been designed to be durable and reliable for all engraving applications. Dust and debris can accumulate in bearing lubricants, effecting their smooth operation. The bearing inserts are designed to push debris into the built-in grooves. Also, the optics in our laser systems can be removed for cleaning and/or replacement without effecting laser beam alignment. The motors and electronics used in our motion system allow Xenetech customers to run their laser systems 12-16 hours per day at maximum speed, every day. The encoder used in our system feeds back to our electronics 8000 counts per revolution for accurate engraving location. Finally, we use the high quality, industry standard tubes manufactured by Synrad and Coherent-DEOS.

At Xenetech, we feel that our systems are the best in the market. We consider our company an extension of our customers’ businesses, providing innovative, technological solutions to help them succeed. Please contact us, if you are interested in any of our engraving systems.
