How do I choose the right laser machine for my jewelry business?

A few things to consider:

• What materials you work with most
  (Metals → fiber laser is usually best)
• Your main use
  (Engraving vs welding vs cutting)
• Production volume
  (Occasional custom work vs daily production)
• Ease of use
  (Software, setup, training required)
• Support and service
  (Important if this is a key part of your business)

If you're mainly engraving metal jewelry, a fiber laser is typically the safest and most versatile laser.
