We noticed internal channels are blocked if not allowed to sufficiently drain. The viscosity of the resin requires the build plate to be lifted above the resin surface for drainage to properly occur. Our experiments show that internal details for vascular flow phantoms can be greatly improved using this method, albeit at the cost of increased print time. We've been able to achieve ~0.5mm channels. Ideally, the option would allow us a retract after a specified number of layers versus after each layer. This will reduce the impact on the total print time
