Ceramic mold preparation method based on 3D printing technology
The invention discloses a preparation method of a ceramic mold based on a 3D printing technology, which comprises the following steps: firstly prefabricating powder by using a binder A, then printing the mold by using the prefabricated powder and a binder B, curing and sintering, so that the prepared ceramic mold has good porosity, collapsibility, high-temperature bending resistance, high-temperature tensile strength and high-temperature compressive strength, and a printing head is not blocked in the printing process. According to the preparation method of the ceramic mold based on the 3D printing technology, on one hand, the problems that a binder A blocks a printing head, and the service life of the printing head is shortened are fundamentally eradicated; on the other hand, the ceramic mold cost is effectively reduced, and the manufacturing period is shortened; and moreover, the porosity, collapsibility and high-temperature stability of the ceramic mold are effectively improved, and the high-temperature bending resistance, tensile strength and compressive strength of the ceramic mold are improved, so that the ceramic mold does not deform in the casting punching process and does not crack in the casting solidification process.
本发明公开一种基于3D打印技术的陶瓷铸型的制备方法,先使用A粘结剂预制粉料，再使用预制粉和B粘结剂打印铸型，固化、烧结后，本发明制得的陶瓷铸型，具有良好的孔隙率、溃散性和高温抗弯、抗拉、抗压强度，打印过程中打印头无堵塞。本发明公开的基于3D打印技术的陶瓷铸型的制备方法，一方面，从根本杜绝A粘结剂堵塞打印头，降低打印头寿命的问题；另一方面，有效降低陶瓷铸型成本，缩短制作周期；并且，有效提高陶瓷铸型的孔隙率、溃散性和高温稳定性，提高陶瓷铸型的高温抗弯、抗拉、抗压强度，使铸造冲型过程中陶瓷铸型不变形，铸件凝固过程中陶瓷铸型不开裂。
