Engraved on Plastic

Acrylic is an excellent choice for a wide variety of projects and design needs. It is easy to work with, comes in a variety of colors and thicknesses, has great chemical resistance and has excellent machining and optical properties. Use acrylic in applications such as point-of-purchase displays, electronic equipment panels, industrial guards and architectural applications. Acrylic works very well with a solvent glue to weld several cut pieces together. Our laser process works very well with acrylic, and is able to engrave text or images into the surface, as well as to cut out unique shapes.

Acrylic is a top performer in the laser engraver. The laser cuts clean smooth edges with no burn or singe marks. Laser engraved acrylic does have a build up of white dust or burnt ash in cracks and crevices. This dust can be blown away with compressed air or lightly brushed away with soft-bristled brushes. Do not use any harsh solvents or window cleaners to clean the surface. We recommend a mild soap or cleaners designed specifically for acrylic or plastics. For those who wish to use a solvent weld or glueing method, we recommend annealing acrylic prior to applying the solvents to avoid a problem called crazing (small microfactures in the edges of the cut that become visible when applying solvents to the acrylic). For a minimal additional charge Working Widget Technology does offer an annealing service, available at checkout.

Standard cast acrylic plastic, acrylic plastic sheet, and other cast resins generally laser very well. A commonly engraved award is a cast acrylic shape designed to be lasered from the back side. Styrene (as in compact disc cases) and many of the thermoforming plastics will tend to melt around the edge of the engraving spot. The result is usually "soft" and has no "etch" contrast. The surface may actually deform or "ripple" at the lip areas. In some applications this is acceptable; for example date markings on 2-litre soda bottles do not need to be sharp.
