Mr Zyzalo investigated the use of layer projection with digital light projection in lazer- based stereolithography to improve fabrication speed by curing at once an entire layer of epoxy-based resin. Mr Zyzlo improved the Limaye mathematical model for single layer exposures and applied the model to a projection-based stereolithography apparatus designed and constructed for the research. He used experiments to determine whether modulation of the projected image would produce an evenly distributed irradiance and account for errors in the optical imaging system. His results showed agreement to within 18% of the improved model. Mr Zyzalo’s findings contribute to the current research trends for improvement techniques in stereolithography fabrication.
