Laser Metal Cutting

Chemical etching and laser metal cutting are two methods used for the precision machining of metal parts. Depending on your application, one method may be better suited than another-or, both methods may be best. For example, Fotofab may choose to use lasers for sheet metal cutting where certain features (holes, slots, etc) smaller than 0.004" (.102mm) are required. Below is a comparison chart that shows how laser cutting and chemical etching metal parts compare:
