Laser engraving is a big part of our business at Laser Cutting Shapes, often done for gifts, wooden and acrylic signs, and artwork. Lately we are producing a large number of felt wall covering panels that are laser engraved.
Laser engraving, etching and marking are very similar approaches that can be difficult to distinguish but provide avenues for artwork to be displayed on wood, acrylic, marble, glass, chrome, and granite and even on coated metals. Typically Laser Cutting Shapes will provide a resolution between 70 - 300 for low to good resolution. Above 300 DPI is a very fine and slow process of laser engraving.
Marking leaves a contrasting color on metals by application of a water-based chemical. However, this is usually avoided and instead approached by using fine laser marking of anodized aluminum.
Etching ablating the very top surface of the material. Typically 0.001" of the material is affected.
Engraving is done for more 3-D like images by removing material that gives depth of cut. Laser engraving time is longer for high DPI images.
