MCOR announced their new Matrix 300+ paper-based 3D printer. This device is similar to the 300, but offers improved performance in how the models are constructed.
They've included a new feature called "Selectable Layer Thickness", in which you could print in either "Draft" or "Presentation". We suspect what might be happening here is that instead of a single sheet of paper per layer, Draft mode would use multiple sheets per layer. This would make printing substantially faster, but produce less detailed prints.
MCOR has also included something called "Variable Volume Deposition", which "enables the production of more complex parts that are even stronger and more durable." We're not exactly sure what this means, but it could be a different method of structuring layers for parts with complex geometries.
