Popis:	This study seeks to understand the impact of process variables, especially UV light distribution, on the 3D fabrication of micro features at the optical resolution scale. In CLIP 3D technology, a Digital Micromirror Device (DMD) is used to create a pattern of projected UV light by controlling each pixel independently. However, as the light outputs of the projected pixels are partially overlapping, there are challenges in obtaining the targeted size and shape of microscale features. From our study, 1. the applied exposure has a direct effect on the size of small printed positive features; 2. smaller sized negative features are even more sensitive and require a careful tuning of the applied exposure to successfully print desired fine structures. Overall, the applied exposure, particularly the UV dosage is critical in the accurate fabrication of micro features that incorporate negative and positive features.
