Firstly, the sand table model maker peeled the copper wire and wire, twisted the copper wire into the shape of a tree trunk, and sprayed paint. Generally, the sponge is dipped in paint and damaged after drying. The branches of the tree trunk are dipped in glue and pasted with crushed sponge to make a tree. If it is a green tree, sponge can be dipped in green paint; if it is a tree in autumn, it can be dipped in orange paint.

Willow can be twisted into tree trunk and branches with 0 or 2mm enameled wire, and then stick green wool on the branches. The pine tree is to cut the thick fishing line into thin sections, clamp them with clamps, and then clamp and twist two 0 and 5mm enamelled wires. Release the clamps to form a pine tree. Trim it and stick green wool powder. Other flowers and plants can be cut and dyed with dried flowers. Use medical cotton swabs or toothpicks to make street lamps. Foamed plastic can be carved into the shape of false rocks with a blade and sprayed with paint.

These accessories are common in the manufacture of sand table models, but when combined, they will have an unexpected visual shock, so we can also store these things in our life, and take them out to imitate how to make sand table models in our spare time.

1. Although the plaster model data is convenient to form, it is easy to cast directly, turn and form, scrape and form the template, process after turning the rough mold, and cast and form the skeleton; However, if a large model is made of gypsum, it will be overweight, difficult to move, simple to damage, and poor in connection with other data.

2. The advantageous aspects of wooden model materials are light weight, small density, plasticity, easy processing, molding and finishing, beautiful raw materials and color patterns; What is not good is that it is flammable, vulnerable to insect disasters, and will show cracks and zigzag deformation.

3. The favorable aspects of FRP model data are high strength, good damage safety, and superior molding technology, which can produce batch products. In addition, it has a good application function in raw material processing such as painting on the surface of FRP materials, especially in the late model manufacturing of large products, which has the advantage of no replacement. It can also play the same role as the products on the production line in the trial production stage of some products; The disadvantages are poor wear resistance and troublesome mold turning.

4. The advantages of paper model materials are low price and high quality, and wide application scope; It has various varieties, specifications and colors, and is easy to be folded, cut, processed, changed and shaped; Quick start and strong expression. The disadvantages are poor physical performance, low strength, strong hygroscopicity, and easy deformation due to moisture Building model During the manufacturing process, the bonding speed is slow, and it is difficult to repair after forming.

5. The plastic model information is light in weight, high in strength, good in chemical corrosion resistance, excellent in insulation function and wear resistance (except for foamed plastic). Thermoplastic plastic can also be formed by heating (such as PVC, plexiglass, ABS plastic), with good molding effect; The disadvantage is that processing is time-consuming.

6. Due to the excellent function of the data processing, the clay model data processing is not only convenient for processing, but also has strong plasticity, and the appearance is not easy to crack, and can be polished and coated after polishing and scraping, and can also be repeatedly modified and recycled, so it is more suitable to manufacture some models with complex shapes and large volumes; The disadvantage is that on the one hand, the accuracy of model size is difficult to grasp, which requires accurate lofting or three coordinate point measurement and symmetrical positioning processing to effectively ensure the accuracy of shape. On the other hand, when manufacturing large models, it is necessary to cooperate with other materials to save data costs and ensure the strength of models.
