Abstract Scope |
Digital Light Processing (DLP) is an emerging technology being used in ceramic additive manufacturing. As DLP technology evolves to support commercial-scale production, a more comprehensive understanding of the effects of each stage of the process can be leveraged to design the ideal part for a given application. It is possible to tailor the properties of individual parts from a single print job or furnace run by adjusting print parameters and thermal processing methods. For example, by modifying select print parameters, the 4-point bend strength of 3D printed alumina can shift from 199MPa ± 99 to 322MPa ± 51, showing an improvement in both strength and material consistency. This study demonstrates the variation in density, grain-size, and strength that can be achieved by adjusting printing parameters in conjunction with thermal processing parameters. |
