Alumina ceramics printed by multi jet fusion and stereolithography

This study examines the feasibility of printing ceramic parts using MJF process. By using HP’s MJF machine, alumina and PA12 powder mixture was used to print ceramic samples. It was found that even though the parts were printed, it was difficult to be removed from the build platform as the samples a...

From the bending tests, it was found that compression rate did not have a significant impact on the Flexural modulus, maximum stress and strain of the alumina samples. The Flexural modulus was between 23.68 GPa to 17.4 GPa and the maximum bending stress before fracture was between 175.54 MPa and 201.96 MPa. For future works, alumina samples will need to be printed via MJF and experiments need to be conducted on the samples to study on its mechanical properties, which can then be used to compare with SLA printed specimens.
