I. Why Choose Liquid Silicone Rubber?
Core Advantages of Liquid Silicone Rubber as a Model Material:

High Detail Replication Capability: Excellent fluidity, capable of deeply filling fine textures of the prototype (such as skin folds, hair roots, scale patterns, etc.), with a restoration accuracy of over 90%.
Elasticity and Durability: After curing, it is soft and elastic, resembling the touch of animal muscle, and resistant to high and low temperatures (-50°C to 200°C), anti-aging, and less prone to cracking or deformation during long-term storage.
Operational Flexibility: Curing time can be controlled by adjusting the formulation (ranging from a few minutes to several hours), suitable for mass production or manual crafting.
II. Detailed Production Steps
1. Preliminary Preparation: Prototype and Material Selection
The core of model making is "replicating the prototype." The quality of the prototype directly determines the precision of the final model. The following preparations must be completed first:

Prototype Creation
The prototype must accurately reflect the morphological details of the animal. Common sources include:
Legally obtained real animal specimens (ensure compliance with source regulations and avoid using protected species);
3D printed models (generated by scanning real animals or 3D modeling, suitable when physical specimens are unavailable);
Hand-sculpted prototypes (shaped using clay, oil-based clay, etc., suitable for artistic creation).
Note: If the prototype is a real specimen, surface treatment is required first (e.g., removing moisture and oils to avoid affecting silicone rubber curing).
Materials and Tools Checklist
Liquid Silicone Rubber: Priority should be given to addition-cure silicone rubber (shrinkage rate <0.1%, environmentally friendly and odorless, suitable for fine replication), such as models HS-30 and HS-50 (numbers represent hardness; 30 Shore A is softer, suitable for skin; 50 Shore A is harder, suitable for bone-exposed areas).
Auxiliary Materials: Silicone rubber curing agent (A/B components mixed in proportion, typically 1:1 or 10:1), release agent (vaseline, silicone oil, or specialized release spray to prevent silicone rubber from sticking to the prototype), mold frame (made of wood or acrylic board, 1~2cm taller than the prototype).
Tools: Electronic scale (accuracy 0.1g to ensure precise mixing ratio), stirring rod (plastic or glass material to avoid scratching the container), vacuum machine (optional, for removing bubbles), scalpel, sandpaper (800~2000 grit).
