Case study of making sand table model for amusement park

Case study of making sand table model for amusement park:

1、 Material selection

The main structure adopts a solid wood frame and is covered with PVC board as the bottom plate, which combines strength and aesthetics. The main body of the building is made of ABS engineering plastic board, which is precisely cut by laser cutting; The amusement facilities (slides, climbing frames) use ABS boards and metal brackets to ensure load-bearing capacity and shape. The road uses PVC simulated pavement to simulate the texture of asphalt and cement; The water body adopts LED light strips and transparent resin, presenting flowing light and shadow after being powered on at night. Vegetation selection includes simulated lawns, shrubs, and trees, paired with detailed materials such as moss and grass; The lighting system adopts LED point light source and line light source to achieve lighting and atmosphere creation of amusement facilities.

2、 Production process

Bottom plate and frame: After polishing and grinding, the solid wood frame is covered with PVC board on the surface, and the edges are fixed with wood glue and fixtures to ensure flatness.

Architecture and Facilities: After cutting ABS boards, the main body of the building is assembled through splicing and bonding. Amusement facilities (slides, climbing frames) are fixed with metal brackets, and gaps are filled with soil.

Roads and water bodies: PVC pavement is cut in proportion, glued to the bottom plate, and the edges are polished smooth with sandpaper; First lay LED light strips in the water area, then cover them with transparent resin to simulate water ripples.

Vegetation and Lighting: Simulated vegetation is planted proportionally, trees are fixed with clay, and shrubs are glued together; LED lights are connected to the power box through wires to achieve zoning control.

3、 Post processing and coloring

Surface treatment: Polish the building surface with sandpaper, fill the gaps with soil, and spray primer (such as white primer) to enhance adhesion.

Coloring process: Using the "layered coating method", first spray the base color (such as gray on the exterior wall of a building), then spray the middle layer (such as red on the roof), and finally spray the topcoat (such as white on the wall). Use a thinner to transition between each layer to avoid color difference.

Detail depiction: The building doors and windows are protected with covering liquid, and the edges are trimmed with a 000 grit pen; Vegetation is simulated with a spray bottle to create a sense of moisture, while trees are textured with a marker pen.

Lighting debugging: LED light and electrical testing, adjusting brightness and color temperature to ensure that the night effect is coordinated with the daytime scene.

4、 Quality Inspection and Delivery

Dimensional inspection: Use a tape measure to measure key parts such as buildings, roads, and water bodies, with an error controlled within a 1:100 scale.

Functional testing: lighting system power on test, vegetation fixation firmness test, road smoothness test.

Appearance evaluation: Observing in natural light and lighting environment, the color transition is natural, and the details are clear and visible.
