MOLDING SAND MOLD COMPRISING SMAE AND METHOD OF MANUFACTURING SAME
The present invention relates to molding sand for producing a sand mold, which is applicable to 3D printing, a molded body comprising the same, and a manufacturing method thereof. The molding sand and the molded body comprising the same according to the present invention can withstand expansion in a molten metal process and have the effect of sufficiently removing gas generated during the molten metal process without additional heat treatment. In addition, by using aggregates of 150 μm or less, it is possible to secure air permeability, reduce the occurrence of defects, and reduce the amount of materials used.
본 발명은 3D 프린팅에 사용할 수 있는 사형 주조용 주물사, 그를 포함하는 성형체, 및 그의 제조방법에 관한 것이다. 본 발명의 주물사 및 그를 포함하는 성형체는 용탕과정의 팽창을 견딜 수 있으며 추가적인 열처리 없이도 용탕과정에서 발생하는 가스가 충분히 제거될 수 있는 효과가 있다. 또한 150 μm 이하의 골재를 사용함으로써, 통기성을 확보할 뿐만 아니라 결함 발생률을 줄일 수 있으며, 쓰이는 재료의 양도 줄일 수 있는 효과가 있다.
