Method for preparing iridium crucible by using 3D printing technology

The invention provides a method for preparing an iridium crucible by using 3D printing technology. The method for preparing the iridium crucible by using the 3D printing technology comprises the following steps that step 1, iridium powder is mixed with superfine epoxy resin to prepare an iridium powder base material by selective laser sintering; step 2, the iridium powder base material is preparedinto an iridium crucible body by using a selective laser sintering 3D printer; step 3, the iridium crucible body obtained in the step 2 is subjected to roasting; step 4, the iridium crucible body roasted in the step 3 is wrapped by a package sheathing, and after vacuumizing the package sheathing wrapping the iridium crucible body, the iridium crucible body wrapped by the package sheathing is putinto a cold isostatic press for densification treatment; and step 5, grinding and polishing are carried out. According to the method for preparing the iridium crucible, the process is simple, the production efficiency is high,
