Top 10 Questions for Laserist Interview

1. Explain the process of laser engraving and how it differs from laser cutting?

Laser engraving is a process that uses a laser to create a design on a surface by removing material, while laser cutting uses a laser to cut through a material. Laser engraving is typically used for creating decorative designs or logos, while laser cutting is used for cutting out shapes or components from a material.

• Laser engraving removes material from the surface of a material to create a design, while laser cutting cuts through the entire material.
• Laser engraving is typically used for creating decorative designs or logos, while laser cutting is used for cutting out shapes or components from a material.

2. What are the different types of lasers used in laser engraving and cutting?

Types of lasers used in laser engraving and cutting:
