A&E JUNE 2016 • 19 Laser Engraving laser beam a couple of inches of dead airspace to disperse." Kurt Koser, GCC Lasers, reminds us that "lasers cut by vaporizing the mate- rial," which in turn creates a by-product that is "even more flammable in a vapor form." As most materials are more flammable in vapor format, Koser rec- ommends the quick removal of exhaust underneath the intended product. James Minchau, Trotec Lasers, mir- rored that statement, saying that when the laser beam "finally bursts through the substrate, the smoke, flame, mois- tures and laser energy are allowed to pass through the material into the airspace below." Minchau adds that "without this airspace, you will get the smoke and resin mixing with any mois- ture," which could damage the backside of your material. TABLE DESIGNS Laser cutting tables are available in many different sizes and designs. The honeycomb table is quite common, but there are other variations of the cutting table. There are tables that use a blade system, which resemble numerous thin blades pointing up. The blade system minimizes contact with the products and allows adequate airflow under- neath the object. Other forms of laser cutting tables use a pin system, allowing the object to sit on pins while the fumes are extracted underneath. If you want a laser cutting table that has been tested to work with your par- ticular laser, contact your laser manufac- Epilog Lasers offers different variations of laser beds.
