Faster resin printers are a hotspot for venture capital right now. The primary stumbling block in this technology is the layer separation mechanism. These printers all pull a model out of a vat of resin "Terminator" style, using an upside down build platform and a light source beneath the bottom of the transparent resin vat. What this means is that, after curing a layer, the build platform lifts one layer height and the next layer is cured. The problem is, after curing, the resin is liable to be bonded to the bottom of the vat, preventing the platform from being able to pull away from the vat.
Solutions are either mechanical or material.
