Abstract
Methods and devices for etching patterns on interior surfaces of hollow objects are described. The method may include preparation of the interior surface of the object, such as pre-cleaning, and coating the interior surface of the object. A pattern may then be generated on the interior surface of the object by any of mechanical or manual scribing and peeling, laser ablation, or photoresist coating and laser exposure, development and hardening. The pattern is then etched using chemical etchants, and finished to remove remaining coating, provide surface passivation and/or protectant application. Mechanical and laser devices which may facilitate pattern generation are also described.
