Case study of sand table model production for residential buildings

This project is a high-end residential building sand table model that focuses on the overall presentation of building layout, landscape atmosphere, and nighttime lighting effects. It accurately reproduces community planning and architectural details, achieving over 90% realistic reproduction and becoming the core visual carrier for project display and customer communication.

In material selection, the core principle is "realistic texture and stable structure". The main body of the building is made of high-density ABS sheet and acrylic composite material, balancing fine carving and structural strength; The exterior facade of the building is made of matte textured panels, and the lines and layers of the building facade are restored through layered splicing. The landscape area is based on simulated grass, with micro shrubs, trees, and flowers of different heights, creating a natural greening effect through the layering of materials and colors. The road section is made of wear-resistant PVC sheet, which is finely cut and shaped to restore the direction and width of the community road. Transparent guardrails and signage are made of high transparency acrylic to ensure visual transparency and clear information.

The production process follows the process of "base construction - architectural refinement - landscape creation - lighting integration". Firstly, the sand table base is made by splicing and leveling the boards to ensure overall flatness. Subsequently, the main structure of the building was constructed using a combination of laser cutting and manual polishing to accurately restore details such as the building outline, balconies, and bay windows; The roof is treated with layered bonding and shaping to restore the layering and decorative lines of the sloping roof. In landscape construction, manual planting techniques are used to distribute green plants according to the planned density, combined with handmade leisure facilities, street lights, and signage, enriching the community's living scene. Road markings and details are manually drawn to enhance the realism of the scene.

Post production coloring and lighting treatment are the key to improving restoration. The exterior of the building adopts a multi-layer spray painting process, with beige and light gray as the main colors. Through color transition and color separation processing, the texture and light and shadow effects of the real building are restored. The landscape area creates a natural sense of layering through manual blending and color overlay. The lighting system adopts miniature LED light strips and point light sources, arranged along the building outline, roads, and landscape nodes, presenting a soft and uniform lighting effect at night, enhancing the atmosphere and visual impact.

In the stage of detail optimization, the model is comprehensively polished and adjusted, the joints are repaired, and the proportion relationship between green plants and buildings is adjusted to ensure overall coordination. The final product, through the synergy of materials, craftsmanship, and lighting, fully presents the community planning and architectural style, meets the needs of display and communication, and has gained high recognition from customers.
