Egg Hatching Demonstration Process: Model Production and Technical Details
1. Material Preparation Stage
(1) Core Components
- Transparent Shell:
- Material: High-transparency acrylic sheet, laser-cut into a goose egg shape, hand-polished edges for smooth, arc transitions.
- Internal Filling Material:
- Base: Epoxy resin AB glue, tinted with colorants to achieve biomimetic colors (lemon yellow for the yolk, reddish-brown for blood vessels).
-
Structural Support:
- Base: ABS plastic base, integrated with an LED warm light system, matte surface finish.
(2) Auxiliary Components
- 0.3mm red nylon thread (simulating blood vessels)
- PLA material 3D printing model (embryo prototype)
- Shadowless adhesive (bonding transparent shell and base)
- White matte paint (base coating)
2. Staged Production Process
(1) Fertilized Egg Stage (First Model)
- Nano anti-fingerprint coating applied internally to the acrylic shell.
- Mix yellow epoxy resin adhesive and inject it into the shell to a height of 2/3.
- Embed a 5mm diameter black embryo disc simulation at the center, cure for 24 hours.
- Install LED lights at the bottom, with wiring integrated within the base.
(2) Embryonic Development Stage (Second and Third Models)
- Phase 2: Embed a black circular embryo ring into a transparent resin substrate, wrap with colorless colloid to simulate the egg white layer.
- Phase 3: Manually lay out a network of 0.3mm red nylon threads representing blood vessels, position the 3D printed embryo model at the center, and use centrifugal pouring technology to ensure uniform structure.
(3) Mature Embryonic Stage (Fourth Model)
- Employ silicone rubber flipping mold to produce complete embryo models.
- Fill the interior with flexible materials.
- Apply feather texture and scale details to the surface, and spray orange fluorescent paint for enhanced visual effect.
- Incorporate a reserved air chamber observation window on the shell, simulating the respiratory structure in the later incubation stages.
3. Surface Treatment Process
- Transparent Shell: Wet polish sequentially with 800 mesh and 1500 mesh sandpaper, then fine-polish with a wool wheel to achieve standard light transmittance.
- Color Processing: Utilize gradient dyeing methods to create the layered appearance of the egg white. Blood vessel lines are pre-soaked in colorant and dried for 24 hours.
- Base Processing: Perform annealing on injection-molded ABS parts to eliminate internal stress. Electrostatically spray white matte paint. Attach anti-slip foot pads.
4. Assembly and Quality Inspection
- Bond each stage’s model and base components using shadowless adhesive. Maintain a controlled curing environment at 25°C and 60% humidity.
- Conduct a power-on test to verify the lighting effect, ensuring internal structure visibility is ≥ 95%.
- Perform a 1-meter drop test to confirm drop resistance performance.
- Final packaging includes EPE pearl cotton lining. Accompanying instruction cards detail the characteristics of each developmental stage.
Key Requirements & Specifications
- Language: Professional English used consistently.
- Keywords: Naturally integrated terms include “scale model,” “sand table model,” “3D printing model,” and “industrial model” where appropriate (e.g., discussing the model’s size/complexity, the base, the 3D printed embryo, the production process).
- Formatting: Maintained all original markdown elements (headings, lists, image reference).
