In the production of sand table model, we should consider the particularity of sand table model material, load and production technology, so we should use the principle of true display according to scale and not according to scale exaggeration or drawing representation to deal with all kinds of landform. Next, Jinan model company will tell you how to make sand table model landform.
First of all, the landform model is generally terraced, which can better reflect the main effect of contour lines, high precision, unique and vivid overall effect. At present, the high density and strong sponge material, which is light weight, easy to cut, easy to set and easy to deform, is used to make mountain. The auxiliary materials include artificial plywood, foam board, cardboard, gypsum and so on. The specific production method is as follows.
1、 According to the size of the vertical scale, the contour lines of contour, material thickness and foundation are determined.
2、 Plotting, copying and cutting of contour lines. Color pen is used to mark and draw contour lines comprehensively. When copying contour lines on strong sponge materials, the order from low to high should be marked, and the number of layers should be marked. Then cutting along the line should be done layer by layer.
3、 Sticking nails on the mountain. The "terrace" of the bottom layer shall be accurately pasted on the chassis with emulsion paint, and then superimposed and bonded layer by layer. The places with poor fit between layers shall be trimmed with scissors or scalpel at any time. For rivers and lakes, when organic glass is used as raw material, the water blue plexiglass is first pressed under the reference starting surface, and then glued with latex and other glue to form the rudiment of landform.
4、 Pile up plastic filling work. In order to change the simple form of the stepped landform into the natural surface form, it is necessary to make filling materials for heap molding. The filling material is composed of gypsum and elm bark powder in the proportion of 4:1 in volume or 2:1 in weight. In order to make the landforms conform to the field conditions, we should carefully study the data verification, carefully study the geomorphic characteristics of the region, fill the terrace like landform into the actual natural surface according to the map, especially create the important geomorphic features, and try to fill in the plastic once. When it is really necessary to do secondary filling, it must wait until the materials of primary plastic stacking are completely dried. At the same time, pay attention to the location of roads and rivers for excavation. After filling, check and accept in strict accordance with the topographic map and other data, so as to ensure the correctness and lifelike image.
5、 Beautify the surface work. After the model is dried, water system and other elements can be excavated according to the map, and then the landform can be colored. The pigment can be oil painting color or advertising color mixed with proper amount of glue. In general, natural colors are used in the coloring style; sand table landforms in high altitude or large elevation difference areas can be colored in layers, in the order of green, yellow, brown, and earth red, and each color should change from light to deep and gradually change.
The above is about the sand table model terrain production methods, I hope to help you, if you want to know more, please click: Jinan model company http://www.jnsymx.com 。
