Error transfer route in SLS rapid investment casting process

SLS rapid investment casting generally needs three steps: SLS prototype firing, wax impregnation post-treatment and investment casting. Because there is a certain size error transfer between SLS prototype wax mold casting, in order to ensure that the final casting can meet the corresponding size accuracy requirements, the size error...
