Nanoscale 3D printing enables a wide variety of applications from photonics to biology. Specifically, using a DMD to project light into a triplet fusion upconversion 3D printing resin can allow rapid printing. This requires selecting a single plane at a time. However, as an image is projected into the resin, the z-resolution of the printing system can be limited by substantial light intensity around the focal plane. Using a home-built setup, we study how we can manipulate the images uploaded to the DMD to optimize the resolution of our prints. We present our findings towards high-resolution nanoscale volumetric 3D printing.
