Play Mode: Eggshell Mold Making

Instructions:

Inject soft-gel material into ultra-thin-walled molds to create hollow, detail-rich structures. This method is commonly used in education, biomimetics, and soft robotics.

Steps:

  1. Create a thin-shell mold (recommended: print resin molds using an LCD/DLP 3D printer).
  2. Inject the soft-gel material into the mold (heat and inject with Saltgator).
  3. After cooling, remove the “eggshell” mold to obtain a hollow soft-gel product.

Recommended Mold Materials:

  • UV Resin
    • Suitable for LCD / DLP photopolymer 3D printing
    • Smooth surface, fine details, easy demolding

Application Examples:

  • Vascular Teaching Model
    • Complex structures with high realism, used in medical training and education
  • Pneumatic Bionic Muscle
    • Enables controllable deformation, suitable for robotic joints and biomimetic mechanical structures
