Before adding artwork or decoration, the pop-up mechanism must work. Paper engineers begin by mapping folds, tabs, and angles to ensure that each part opens smoothly and closes flat.
Even a slight shift in alignment can affect how a card functions. That’s why laser cutting is essential for precision. At Viet-Craft, we create prototypes to test balance, symmetry, and motion before production.
3D effects are built using layers — front, middle, and back. When engineered well, the design feels dimensional, almost theatrical. Flowers bloom. Buildings rise. Characters pop forward from the scene.
From spinning wheels to floating elements, interactive features like pull-tabs and rotating parts make cards more playful. These advanced mechanics require careful planning and strong materials.
Paper engineering isn’t just technical — it’s artistic. A successful pop-up card surprises and delights while staying functional. The best designs balance movement, message, and emotion.
