Hello. I am Instructor Park Ji-hyun (Jeong Seong-gadeuk). It has been seven years since I started working as a 3D printing instructor. I mainly conducted offline classes before I discovered Kookoog. As generations change, there is a growing trend toward finding items that are uniquely one's own—even unique colors and scents—rather than mass-produced goods. One educational course that fits this trend is 3D printing, a field within the Fourth Industrial Revolution. Does the word "3D" sound difficult? Not at all! From now on, as we navigate the 3D printing process—which might otherwise feel daunting—by designing the items you need yourself through 3D modeling and creating your own unique merchandise, you will gradually come to appreciate the charm of 3D printing. If I need it, I design it! Isn't that cool? See you at Kookoog!
