Thunder Laser’s product line is built to exacting specifications and they have rigorous quality control and continuous improvement standards. Thunder Laser is, in my opinion, the best, with Aeon pulling a very close second and Boss trailing closely behind that. They do not suffer from a lack of design or quality yet the stigma associated with the low end clones still unfairly follows them. The High End Chinese made laser engravers are very impressive, even against Epilog and ULS and the price point is better than you think as compared to the US lasers. The price tags on US laser engravers can be intimidating especially if you are not running a full-fledged laser engraving business. Other models include Trotec, Rabbit, Boss (Made in China but heavily supported in the US), and I’m sure there may be more. The US made laser engravers are high quality, high precision workhorses that will last forever if properly maintained. Low End: Chinesium Clones (k40, etc…): $350 and up High End (ULS, Epilog, etc.): $20K and up Would you anticipate expanding in the near future? Some of which are:ĭo you know what materials/product you plan on lasing? There are many considerations which need to be addressed. FIBER, CRYSTAL, AND OTHERS WILL BE ADDRESSED IN FUTURE ARTICLES. NOTE: WE ARE FOCUSING ON TYPICAL C02(GAS) LASER SYSTEMS HERE. You can get either source in either beam delivery method and there are also dual source units (mostly gantry like epilog fusion). Not all fiber lasers are galvo and not all CO2 lasers are gantry. Galvanometers (galvos) steer the beam with oscillating mirrors (think walmart scanner at the checkout). Gantry lasers have rails and a carriage and steer the beam with stationary mirrors mirrors and lenses. DC excited laser tubes have a minimum excitation threshold meaning they will not fire below a certain power. Metal tube RF sources can maintain a steady beam signature throughout the entire power range and are typically higher resolution than their water cooled DC excited glass counterparts. You will find metal air cooled RF tubes in most US made lasers. Fiber lasers can etch and cut metals.ĬO2 lasers sources are typically either water cooled glass tubes that are DC excited (like 99% of high and low end Chinesium engravers) or metal tubes that are air cooled and RF excited. CO2 will not, reasonably, ablate metals but you can bond pigments to it at the molecular level with special marking compounds. CO2 is best for organics ( acrylic, wood, leather, glass, etc…) while fiber is best on polymers, metals, and such. We will be referencing the 2 most common sources in this section: CO2 and fiber. Crystal (Nd:YAG, Nd:YVO around 1.064μm).The Nitty Gritty Below are 3 of the more popular types of laser sources:
I am glad I did even though I restricted the size of my work area by doing so.

I just sold the ULS and have heavily modified the K40 and it is a freaking amazing wonder! I justified paying as much to mod the laser as it would have cost to buy a bigger machine, brand new with all of the mods needed because I wanted to tear this one down and build it back up myself. I decided to get a K40 Chinese Laser Engraver (a saw one for sale on Craigslist that was still in the box and I couldn’t beat the price) and it took my inner techie-geek to a whole new level! A new Laser module (a Synrad Air-Cooled Metal Tube CO2 laser) was over $8000 and it would cost over $1000 to recharge mine if it became necessary. I am a techie geek and tinkerer with a pretty advanced level of mechanical inclination so I wanted to explore this cool device and learn more.Īfter I got the ULS up and running my research indicated (although this machine is one of the best US made units out there) the parts, should they be needed, are VERY expensive and it was made in 1990 or 1991 so it was pretty old. Then I lucked up and received a ULS-25E in a trade for another piece of equipment because I thought it would be “neat”. It did, however, prime my interest in other laser systems. This is a 1000mW Solid State LD machine and, while interesting, was essentially useless.
I got my first laser, a Meterk DK-8-KZ, because they interested me. 7 Learn more about Lasers, Lenses, Optics, and Focus HERE.2.1 Below are 3 of the more popular types of laser sources:.
