sized jobs with a quick changeover, he says. "A laser engraving and cutting system will vaporize and modify the surface of most materials with the laser beam," Stevens says. "This creates contrast to the work piece, or you can cut through it altogether." Galvo laser systems, typically used in high- volume and industrial applications, can do the same things as the flatbed, but the motion system is fixed and the laser beam is delivered by two mirrors onto a smaller working area, Stevens says. Once either system is in place, there may be a need for upgrades and additional acces- sories, Stevens says. "Laser system upgrades are specific to each laser owner's individual needs; however, increased power for boosted productivity and accessory add-ons that offer more capability are highly desirable options," Stevens says. Laser System Upgrades "The main reasons customers give for wanting the upgrades or add-ons are to increase speed and to be able to engrave or cut thicker materials. A larger laser would allow you to process thicker material or cut at a faster feed rate," Kern says. LASER Photo courtesy of Kern Laser Systems. Photo courtesy of Universal Laser Systems.
