This course focuses on digital 3D modeling tools that can be extended to 2D laser cutting and engraving production. Generally, lasers are categorized into semiconductor lasers, gas lasers, solid-state lasers, and fiber lasers. The course utilizes the existing machinery within the school, primarily focusing on gas lasers, specifically CO2 lasers. Throughout the course, students will learn how to operate these machines, from engraving to learning about cutting power in practice, to get closer to the use of lasers. The course will include learning the concept of marking with semiconductor lasers, corresponding to the marking machines commonly used in the industry, to achieve an understanding of industrial applications.
