Zusammenfassung: | The present invention relates to a hollow jewelry manufacturing method. According to the present invention, the inside of a model, which is three-dimensionally printed as a hollow jewelry product, is manufactured to be kept hollow, and the model is heated and burned to be removed through a gradual temperature rising process after electrolytic casting, so even if resin which is the model is expanded by heat, a crack on a final product can be prevented. In order to achieve the purpose, the method includes the following steps of: (S1) designing a model of jewelry by hollowing the model at 25-70%; (S2) outputting the model of jewelry designed in the step (S1) through a three-dimensional printer; (S3) plating the surface of the model of jewelry outputted in the step (S2) with a conductive metal layer; (S4) forming an electrodeposition layer on the surface of the conductive metal layer plated in the step (S3); and (S5) removing the model outputted in the step (S2) through a gradual temperature rising process making a temperature rise for one hour in a room temperature-200°C section, making a temperature rise for one hour in a 200-300°C section after maintaining 200°C for 30 minutes to one hour making a temperature rise for two hours in a 300-400°C section after maintaining 300°C for 30 minutes to one hour, making a temperature rise for one hour in a 400-650°C section after maintaining 400°C for 30 minutes to one hour, and maintaining 650°C for 30 minutes to one hour from the model of jewelry with the electrodeposition layer formed in the step (S4) to the model outputted in the step (S2).
이 발명은 할로우 쥬얼리 제품으로 3D 프린팅된 모형물의 내부를 중공 상태로 유지하게 제작하고, 전해주조 후에 단계적 승온 과정으로 모형물에 열을 가하면서 태워 제거하여, 모형물인 수지가 열을 받아 팽창하더라도 최종 제품에 균열이 발생하지 않게, 쥬얼리의 모형물을 25~70%로 중공화하여 디자인하는 단계(S1)와; 상기 단계(S1)에서 디자인된 쥬얼리의 모형물을 3D 프린터로 출력하는 단계(S2); 상기 단계(S2)에서 출력된 쥬얼리의 모형물 표면에 전도성 금속층을 도금하는 단계(S3); 상기 단계(S3)에서 도금된 전도성 금속층의 표면에 전착층을 형성하는 단계(S4); 및, 상기 단계(S4)에서 전착층이 형성된 쥬얼리의 모형물로부터 상기 단계(S2)에서 출력된 모형물을 상온~200℃ 구간을 1시간 동안 승온하고, 200℃에서 30분~1시간 유지한 후에 200~300℃ 구간을 1시간 동안 승온하고, 300℃에서 30분~1시간 동안 유지한 후에 300~400℃ 구간을 2시간 동안 승온하고, 400℃에서 30분~1시간 동안 유지한 후에 400~650℃ 구간을 1시간 동안 승온하고, 650℃에서 30분~1시간 동안 유지하는, 단계적 승온에 의해 상기 단계(S2)에서 출력된 모형물을 제거하는 단계(S5);를 포함하는 것을 특징으로 하는 할로우 쥬얼리 제조방법을 제공한다. |
