Sand Table Model Making Guide

Professional-Grade Terrain Sand Table Construction Guide

I. Data Preparation Stage

Terrain Data Collection:

Use drone aerial surveying to obtain 0.5-meter resolution surface data

Perform 3D laser scanning of special geological structures

Divide the digital elevation model into printable modules

Digital Model Optimization:

Use mesh repair software to process scanning noise

Sharpen the edges of features such as cliffs and steep slopes

Design hidden joint slots

II. Printing Material Plan

Base Terrain:

Use gray resin containing basalt powder for the bedrock layer

Use brown-toned resin mixed with wood fibers for the soil layer

Select transparent blue light-curing resin for water areas

Special Treatment:

Add nano-reinforcing agents to steep slope areas

Pre-embed optical fiber light guides at the bottom of rivers

Micro-planting holes reserved in vegetation areas

III. Precision Printing Process

Layered printing strategy:

Vertical direction: color-separated printing according to geological strata

Horizontal direction: radial support layout

Key topographical features: separate close-up slicing

Process quality control:

Dimension verification every 5 cm in height

Special structures: secondary exposure curing

Printing chamber maintained at constant temperature and humidity

4. Post-processing techniques

Surface refinement:

Micro-carving tools used to restore gully details

Sandblasting to create rock texture

Magnetic polishing machine for water surface planes

Ecological Implantation:

Distribute moss communities according to vertical zonation patterns

Use electrostatic flocking technology to create grasslands

Micro-tree species are produced using laser cutting technology

Professional Coating:

Rock layers use mineral pigment dry-brushing technique

Water bodies use gradient airbrushing

Artificial trace areas undergo aging treatment
