 Laser engraving technology is used in drilling holes, with precision. However, in this process it is required to put on protective gears like masks and goggles, etc. Laser etching is generally used in manufacturing process. There you have hand held and machine operated etching machines. These machines are to correct the object to perfection. The machine operated etching machine is for large-scale production. The energy consumption is more in this system. These machines have price tag of $7800- $25000 dollars depending on the prerequisite and its function.
 A rotary engraver is perfect for creating signs in metal, plastic as well as wood and is capable of creating ADA-compliant signs and 2.5 D and 3D effects which are not possible with a laser. While signs can be created on any size engraving table, sizes of 16" x 12" and larger provide the option of not only creating bigger signs, but also creating multiple sign layouts and using time-saving tools such as an Automatic Raster Braille inserter. This article will discuss ADA sign making with a rotary engraver.
