laser cut plastic patterns

Just like glowing plastic patterns this 3 mm thick plastic was shaped by laser cutting. The laser beam is focused through a lens that concentrates the beam to a fine spot between 0.1–1 mm. The high concentration beam melts the material on contact. The laser beam cuts and polishes the acrylic in a single pass, which produces an excellent finish even with intricate profiles and fine details. 

Laser cutting machines work directly from CAD data. This means that data can be translated very readily from a designer’s computer onto the surface of the material. As a result this technology can be utilisied for everything from one-offs to mass production, such as architectural models (see precise paper models) and the Queen Titania light by Luceplan.
