glowing plastic patterns


Laser cutting machines are mesmerising to watch in operation. It is a computer-guided process – data is inputted and the machine runs its course – known as computer numerical control (CNC). One of the many advantages of CNC is the ability to produce extremely accurate parts to precise tolerances.

The scored lines created by the laser cutter appear to glow, an effect known as 'edge glow'. This is caused by light picked up on the surface of the sheet and transmitted out through the edges. The scoring acts like an edge and so lights up in the same way, accentuated by the fluorescing yellow tint.
