(3) Three-dimensional printing performing step < S300 >
In this step, printing of the three-dimensional printed material is performed using the three-dimensional printer based on the printing material composition for photocuring three-dimensional printing produced in the step S200.
Here, the printing material composition for photocurable three-dimensional printing is subjected to a polymerization reaction through a three-dimensional printer so as to correspond to the design through CAD, so that the printing material composition is printed as a three-dimensional printed matter having a certain strength through solidification between particles.

In this step, the process of heating the printed three-dimensional printed material through the step S300 at a predetermined heating rate is performed.
Here, the three-dimensional printed material printed through step S300 is heated until it reaches a temperature range of 1000 to 1100 DEG C at a heating rate of 20 DEG C / min to 40 DEG C / min in air or in a vacuum environment.
(5) Three-dimensional print mooring step <S500>
In this step, a process of waiting the heated three-dimensional printed matter through the step (S400) in the environment of the inert gas for a predetermined time is performed.
Here, the heated three-dimensional printed material is moored in an environment in which argon (Ar) is supplied for 10 to 20 minutes in an environment where a predetermined temperature is maintained within a temperature range of 1000 to 1100 ° C, It is preferable that argon (Ar) supplied after the elapse of the process time of the step is discharged to the outside together with the gas generated in the mooring process.
