Problems solved by technology

[0008] One is that in the existing formula, the epoxy resin curing agent generally adopts 593 type. Since the 593 type curing agent has low activity and slow curing speed, it takes a long time to cure during the casting process of the model, which seriously affects the efficiency of mold making
[0009] The second is that in the existing formula, the highest wave velocity of the prepared model reaches 2600m / s, which cannot simulate the needs of the actual formation, which is not conducive to the production of complex structural models
