Because of the characteristics of resin material, it is very suitable for expressing very detailed details and people. Hand-made white molds are mostly semi-finished products provided by factories, which require a series of complicated processes such as polishing, assembly and coloring, and the difficulty is far greater than that of general model making. Just from the perspective of coloring, you need a certain artistic skill and an expensive painting tool such as a pen.

GK classification:
1, casting resin
Casting resin, commonly known as PU resin, is actually Japanese HEI-CAST resin, which is short for non-foaming polyurethane resin. There are agent A and agent B, and they need the same weight ratio to be mixed.
Colors are white, beige, ivory and so on. (It will be different according to the arrangement number of casting resin, such as 80 12 beige, 80 14 white, 80 17 ivory white, transparent color, or other specially modulated colors). It is a material with light weight, excellent plasticity, best details and very good hand feeling.
Therefore, Cast is the best material for GK model, but the price is more expensive than other materials, equivalent to more than 300 RMB (one kilogram for A and one kilogram for B, with a total weight of two kilograms). It is easier to handle casting resin by hand.
Casting resin mainly includes the original version and the Hong Kong version (please note that it is the real Hong Kong version, not the one that is turned upside down to pretend to be the Hong Kong version).
Japanese handmade materials are generally labeled as cold resin casting kits, and cold refers to the forming process-cold forming, which means that the materials do not need to be heated and melted before entering the mold.
Other plastics (such as pvc/abs/) must be heated and melted before injection molding. Resin is resin, and kit means kit. So the translation is cold-formed casting resin kit.
2. 80 12, 80 14 and 80 17 resins
These three resins are common models in AB water.
Polystyrene polaroid powder resin
Resin mixed with stone powder, a cold resin. The price is cheap, less than 1/3 of the casting resin price. The English name is poly stone, which is the main material for the early completion of humanoid products.
Basically, it is not suitable for manual enthusiasts, and it is the most unsuitable material for GK model. It has the advantages of impact resistance, heat resistance, high hardness, heavy weight, difficult cutting and poor plasticity. You can change the color by adding toner, which is heavy and brittle (for excellent reasons) and very easy to break.
3. PVC
Short for polyvinyl chloride. That is PVC material. Europe and America often call it soft rubber material.
Uncoated parts made of soft rubber (soft rubber parts for short) are different from the first type in the materials of these parts.
The quality is soft and the price is low. The same shape can be bought with less money. In terms of modification, it has greater freedom than resin.
