Problems in making FRP models and models
Method of making die at the end of the lowest cost, is artificial cutting and polishing, wood or other materials can have certain hardness and easy processing stuff, but it requires a very high skill, good feel, and often do it is not precise enough, but for ship model, basically is sufficient.
The bottom and the canopy, this can be directly on the bottom mold the glass fiber cloth can pave the way. Glass fiber cloth can be bent into irregular surface to a certain extent. But this seems to be called "stretch", but change it in different position of the mesh density. In other words, so make the canopy around the grid the top of the grid density, density is small.
The higher precision is the three-dimensional engraving machine, but this machine can generally do very limited volume, can not do big things. This engraving machine usually needs to be polished again after making the bottom mold
