Pros and Cons of Laser Etching Versus CNC Routing

When looking for cutting, engraving, and etching services, you’ll likely encounter two different methods: laser etching stainless steel and CNC routing. Both options focus on cutting and designing various materials for customisation purposes, but each has its unique advantages and disadvantages.

If you need help deciding between laser etching and CNC routing services Perth, we have compiled a comprehensive list of the main pros and cons of both fabrication methods in this short article:

Laser Etching

Laser etching pertains to the process of vaporising the surface of a material bit by bit to leave a distinctive, permanent mark. In businesses, laser etching is widely used to place brand logos and names on various merchandise, signages, and office fixtures. Laser etching uses a variety of machines, including CO2, diode, and fibre optic lasers, to alter the surface of materials.

The Pros of Laser Etching

  • High Precision – Laser etching technology produces precise cuts and shapes no matter how intricate.
  • Versatility – Laser etching is compatible with a broad range of materials, including metal, wood, cardboard, plastic, and glass.
  • Detailing – Do you have a design with highly intricate details that most engraving methods cannot accomplish? Laser etching can create complex designs with ease and precision.
  • Speed – Laser etching has quick turnaround times, making it ideal for mass production.

The Cons of Laser Etching

  • Costs – In most cases, laser etching is an expensive option versus other methods.
  • Health Concerns – Laser etching vaporises materials, which release potentially harmful gases alongside UV rays. Safety precautions must be observed.
  • Compatibility Problems – Certain materials might need a special coating or treatment before undergoing laser etching.

CNC Routing

CNC (Computer Numeric Control) routing uses computerised machines to etch or carve designs, patterns, and other visuals into a surface. The design is created in a software program, which is then translated into G-code that directs the machine where to move and how quickly. 

The Pros of CNC Routing

  • High Precision – Like laser etching, CNC machines produce precise cuts and shapes regardless of design complexity.
  • Repeatability – CNC routing can repeat the same designs multiple times, which ensures quality.
  • Automation – CNC machines require minimal manual labour, saving on labour costs.
  • Speed – Speed is a shared trait between laser etching and CNC routing – both can operate at high speeds suitable for mass production.

The Cons of CNC Routing

  • Skill Level – CNC routing requires technical knowledge and experience to operate properly.
  • Costs – High-end CNC routing machines are expensive to purchase and maintain.
