Coating optimization of yield pseudoplastic paste-based stereolithography 3D printing of alumina ceramic core

Vat photopolymerization 3D printing of Al2O3 ceramic cores with strip‐shaped pores by using polyamide 6 fiber template

“…20 However, by this method, a rapid decrease in flexural strength easily occurs when the porosity is increased to more than 30%, with a maximum value of less than 60 MPa. [21][22][23][24][25][26][27][28][29] With the increasing complexity of ceramic core shapes, the requirements for core strength are increasing correspondingly. Therefore, the development of high-strength and high-porosity Al 2 O 3 ceramic cores has become a core problem that needs to be solved urgently.…”

“…Most of the current studies to enhance the performance of Al 2 O 3 ceramic cores focus on changing the degreasing and sintering process 20 . However, by this method, a rapid decrease in flexural strength easily occurs when the porosity is increased to more than 30%, with a maximum value of less than 60 MPa 21–29 . With the increasing complexity of ceramic core shapes, the requirements for core strength are increasing correspondingly.…”
