Addressing key challenges in multi-material and multiscale digital projection stereolithography (Invited Paper)
28 January 2025 • 4:10 PM - 4:35 PM PST | Moscone South, Room 201 (Level 2)
Abstract
This presentation will include two research projects conducted at Syracuse University and few outreach slides related to opportunities at NSF for the Additive Manufacturing community. First project, entitled, Multi-material Gradient Printing Using Meniscus-enabled Projection Stereolithography (MAPS) addresses current challenges related to vat based multi-material printing associated with hardware modifications, control systems, cross-contamination, waste, and resin properties. We show that MAPS can print 3D structures with gradient properties in mechanical stiffness, opacity, surface energy, cell densities, and magnetic properties. Second project, entitled Multipath projection stereolithography (MPS) addresses the inherent tradeoffs between print resolution, design complexity, and built sizes. Inspired by microscopes that could switch objectives to achieve multiscale imaging, we report a new optical printer coined as MPS specifically designed for printing microfluidic devices. Using a test-case of micromixers, we show user-defined CAD models can be directly input to an automated slicing software to define printing of low-resolution features with embedded microscale fins.

Syracuse Univ. (United States)
Pranav Soman holds two positions, as a Professor at Syracuse University, and as an IPA Rotator Program Director of the Advanced Manufacturing (AM) program at the National Science Foundation (NSF). As an academician, Prof. Soman’s central research focus is to develop new processing and printing technologies to create reliable models to capture key aspects of in vivo physiology and pathophysiology. Toward this goal, his group has developed a technology toolbox to provide a manufacturing solution to advance research in bioprinting, microfluidics, organ-on-chip, tissue engineering, regenerative medicine, and single cell analysis. He is also the founder of 3D Microfluidics LLC (3DM), a startup funded by NSF SBIR grant to provide cost-effective microfluidics solutions to researchers in life sciences. As a recently appointed Program Director at NSF, Prof. Soman’s roles include the advocacy of cutting-edge interdisciplinary research and education across advanced manufacturing fields.
