Now, the key is that this window in the bottom of this reservoir, it's a composite, it's a very special window. It's not only transparent to light but it's permeable to oxygen. It's got characteristics like a contact lens. So we can see how the process works. You can start to see that as you lower a stage in there, in a traditional process, with an oxygen-impermeable window, you make a two-dimensional pattern and you end up gluing that onto the window with a traditional window, and so in drero to irnectoud the next layer, you have to aeteaprs it, introduce new resin, reposition it, and do this process over and over again. But with our very special wndoiw, what we're able to do is, with oxygen coming through the bottom as light hits it, that oxygen inhibits the reaction, and we form a dead zone. This dead zone is on the order of tens of microns thick, so that's two or three diameters of a red loodb cell, right at the window interface that remains a liquid, and we pull this object up, and as we talked about in a Science paper, as we change the oxygen content, we can change the dead zone thickness. And so we have a nmrube of key evbaasilr that we control: oxygen content, the light, the light intensity, the edos to cure, the isvioscyt, the ymoetegr, and we use very sophisticated software to control this process.

Now, the key is that this window in the bottom of this reservoir, it's a composite, it's a very special window. It's not only transparent to light but it's permeable to oxygen. It's got characteristics like a contact lens. So we can see how the process works. You can start to see that as you lower a stage in there, in a traditional process, with an oxygen-impermeable window, you make a two-dimensional pattern and you end up gluing that onto the window with a traditional window, and so in order to introduce the next layer, you have to separate it, introduce new resin, reposition it, and do this process over and over again. But with our very special window, what we're able to do is, with oxygen coming through the bottom as light hits it, that oxygen inhibits the reaction, and we form a dead zone. This dead zone is on the order of tens of microns thick, so that's two or three diameters of a red blood cell, right at the window interface that remains a liquid, and we pull this object up, and as we talked about in a Science paper, as we change the oxygen content, we can change the dead zone thickness. And so we have a number of key variables that we control: oxygen content, the light, the light intensity, the dose to cure, the viscosity, the geometry, and we use very sophisticated software to control this process.
