In this paper, we present a facile way to increase the resolution of 3D printed microstructures to minimally 4 μm by casting-shrinkage cycles of a polyurethane (PU) polymer. A water–PU liquid mixture ...

In this work, we explore how to effectively generate large-scale 3D scenes using the coarse-to-fine paradigm. We introduce a framework, the Pyramid Discrete Diffusion model (PDD), which employs ...
