Laser-Etching Drives Come to the Mac
Ever wanted to laser-etch some labels onto DVDs you've burned, but wanted to do it on your Mac ? Now you can.Laser engraving is the practice of using lasers to engrave, etch, or mark an object. The technique can be very technical and complex, and often a computer system is used to drive the movements of the laser head. Despite this complexity, very precise and clean engravings can be achieved at a high rate. The technique does not involve tool bits which contact the engraving surface and wear out. This is considered an advantage over alternative engraving technologies where bit heads have to be replaced regularly.
For signage and faceplates, etc., special laser-engraving plastics were developed. These incorporate silicate or other materials which conduct excess heat away from the material before it can deform. Outer laminates of this material vaporize easily to expose different colored material below.
Other plastics may be successfully engraved, but orderly experimentation on a sample piece is recommended. Bakelite is said to be easily laser-engraved; some hard engineering plastics work well. Expanded plastics, foams and vinyls however are generally candidates for routing rather than laser engraving. Urethane and silicone plastics usually don't work well-- unless it is a formulation filled with cellulose, stone or some other stable insulator material.

When it comes to so-called heavy metal supergroups, a lot of them usually don’t last long. But for New Orleans’ Down – made up of Ex-Pantera vocalist Phil Anselmo and bassist Rex Brown, Corrosion of Conformity guitarist Pepper Keenan, Crowbar guitarist Kirk Windstein, and Eyehategod drummer Jimmy Bower – there has been something special that has kept them unified for over 15 years.
