Abstract Scope |
While additive manufacturing has been utilized for a wide range of applications, there are still boundaries from it being used in applications that require high resolution or low surface roughness.
One of the applications that currently doesn’t utilize AM are optics as the surface requirements for a usable part are well beyond what can be done on commercial machines. While there are AM methods such as Two-Photon Polymerization that should be able to meet the requirements, the throughput by said method is much too low to be used in any large scale parts.
Our work focuses on the utilization of Digital Light Processing (DLP) and understanding what are the limitations to layer thicknesses. By developing sub-micron layers and characterizing them, we can see how layer thickness varies, material properties vary due to amount of UV exposure, etc.
Results will be discussed in an extended abstract. |
