How to Buy a Laser Engraving Machine
Though there have been other, older engraving methods that are more traditional - diamond cutting, sand blasting or chemical etching, for example - the more modern method of laser engraving offers several advantages. For one, in laser engraving, the material itself is not being touched and, hence, will not be accidentally marred or cut. Laser machines are also highly durable and require minimal maintenance in comparison.
Instructions:
- Consider the size of the items you will be engraving. Make sure you purchase a laser engraving machine that will accommodate the largest item you plan on engraving. Keep in mind that the larger the engraving machine is, the more it will cost so do not overbuy, but make sure the machine you end up choosing will meet all your needs.
- Consider the speed you want for your machine. This is all dependent on how powerful the laser is. Of course, the more powerful and faster the laser, the more expensive. However, a fast engraving machine will be able to handle more work in shorter lengths of time, thereby offering greater efficiency. If you will be using this engraving machine as a business, then this will be most beneficial to you. If speed is not an issue for you, then a slower machine will work just as well.
- Think about if you will be doing very fine, detailed etching, especially on smaller items. If so, you will want to look at machines that have servo or high-precision motors and lasers that offer enhanced options such as beam enhancing or auto focusing optics.
- Look for a machine that comes with a guide light for the laser. This will show you exactly where the laser is pointing and where the etching will be. This offers you the greatest precision and assurance that your engraving will be exact and proper.
- Look for a machine that is equipped with an air blower. This feature follows the laser cut with puffs of air that clear out any debris and smoke from the engraving process. This is especially important if you will be cutting flammable materials, like acrylic. This will be a standard feature on most machines, particularly the newer ones but not all.
