Casting techniques, casts, and three-dimensional printing systems and methods

This invention describes a 3D printing system that builds objects layer by layer. It uses a light source to solidify a liquid material held in a tank, creating the desired shape. A computer system controls the light, specifically adjusting its intensity based on the unique properties of the liquid material being used to ensure proper curing.

Why it matters: Since 2019, advancements in machine learning and sensor technology have made it significantly easier to implement adaptive control systems that can characterize materials and dynamically adjust light sources for optimal 3D printing. This reduces the complexity of developing the intelligent curing process described.
