In addition, wood is easy to absorb moisture and is susceptible to deformation and breakage. In addition, wood has low strength. On the other hand, metal materials are heavy and take time to process. In addition, metallic materials are strong and stiff, which makes shape modification difficult. Therefore, a main object of the present invention is to solve the above-mentioned problems, to provide a prototype raw material having appropriate strength and easy to process, and a method for producing the same.

れる。In the step (a), the predetermined amount of the hollow powder refers to the weight of the hollow powder 2 to 5 per 100 units of the resin.
Desirably, the unit is zero. In the above step (e), at a constant temperature in the range of −10 ° C. to −20 ° C. for 4 hours to 1 hour
Since the hollow powder 10 and the resin 11 are kept for 20 hours, the hollow powder 10 and the resin 11 are gradually crystallized and hardened, and complete crystals with high purity are formed.

題点を解決することができる。Although the hollow powder 10 is protected by the resin 11, there is a small gap between them. In addition, since the resin 11 itself has a predetermined elasticity and toughness, the hollow powder 10
The structural strength of the prototype of this embodiment made of the resin and the resin 11 is smaller than that of metal and larger than that of wood. Therefore, the prototype can be easily processed and has sufficient strength,
Weight can also be reduced. In addition, since the prototype of the present embodiment does not absorb moisture and does not easily deform, it is possible to solve the problem of the prototype made of wood that easily absorbs moisture and is easily deformed. Further, since the prototype of the present embodiment can be easily processed and its shape can be easily corrected, it is possible to solve the problem that it is difficult to process the prototype of the metal material and to modify the shape.
