Inventor here. We are cognizant of the chemical waste disposal concerns and have taken steps to mitigate those hazards in our design. The parts are rough because our current prototype has a very low resolution. Imagine trying to display a picture with a monitor only 8 pixels by 8 pixels. Our next version will have much higher resolution.
