No but seeing that post again got me thinking about the science behind Jaime's bugsuit just conjuring things out of his dead skin cells and sweat

Because you can't just make anything out of your body's waste products. There are specific chemicals that can't be found in your body - or at least, not in large amounts - that are used to make certain objects.

The printer paper for the picture, I can understand. Paper is largely made of carbon anyway so that tracks (lots of carbon / carbonate type of chemicals can be found in a human body).

But his clothes? Stuff like cotton and polyester are all made up of polymers, and once we get into polymers you're talking ester, amine, alcohol, etc. Traces of amine and alcohol can be found in a normal human body, but how much can you really extract from dead skin and sweat alone? Unless Jaime is drinking ethanol (ethyl alcohol) on the regular, it's not gonna be in his sweat all the time. As for ester, it can be found in lipids / fatty acids, which could be found on human skin in the oils produced there, but again, unless Jaime is sweating loads and loads it's not enough to create full clothes out of it.

Assuming that Khaji Da has the ability to break down certain chemicals and polymerise these chemical compounds to generate papers and fabrics — you'd still need a large enough supply of said chemicals in first place, and I don't believe Jaime's body produces enough of them in just his dead skin cells and sweat alone.

The only explanation here is that Khaji carries its own reserves of certain chemicals, which they extract not just from Jaime's bodily waste but from their surroundings as well.

Tl;dr, I believe Khaji, and by extension Jaime, is a walking laboratory storage cupboard full of various chemicals.
