Laser marking is a manufacturing process that uses a focused beam of light to permanently alter the surface of the contemporary art sculpture piece. Unlike laser engraving, it changes the surface without removing material. It produces long-lasting high-contrast marks that can be easily read or scanned.

   There are many laser marking methods available. The four most commonly used are Annealing, Carbon migration, Coloring and foaming. Compared to other marking methods, laser marking offers a number of advantages, such as Higher marking accuracy/precision. The use of lasers enables manufacturers to target highly specific areas on the workpiece. Smaller environmental impact. The laser marking process produces much less waste since it does not require the removal of material from the workpiece to create the desired marks. Better compliance with industry regulations. The permanence and readability of laser-made markings make the laser marking process ideal for adding important information to manufactured components.

   Laser engraving is a manufacturing process that uses a focused beam of light to remove material from the outdoor play equipment or art pieces to form the desired design (e.g., text or image). The resulting marks are durable and resistant to falsification. The three main laser engraving methods are laser etching, laser engraving, and laser ablation. The key difference between etching and engraving and ablation is: Laser etching produces shallow marks. Laser engraving produces deep marks that can withstand exposure to harsh operational or environmental conditions. Laser ablation produces marks by removing surface coatings to expose underlying layers

   Advantages of Laser Engraving are Laser engraving offers a variety of advantages over other marking processes, such as Broader range of depths. Laser engraved marks can be made to varying depths, from shallow to deep. Better durability. The laser engraving process can produce marks that remain highly visible on Large City Sculptures even after being exposed to harsh conditions. Greater marking speed. Laser engraving is the fastest way to produce laser-made markings.
