    Applying desiccant to surfaces (aluminum sheet or PLA/PETG)

    Thanks for your suggestion. Also a descant wheel is not an ERV wheel (which is why I specified I need to apply it to aluminum or a plastic capable of heat transfer). They do different things and are manufactured differently.

    I think i just thought of a great way to do this. I will try to get silica powder, and then surround my 3d printed part in the powder, and then I bake it, this way it will maintain its shape and a thin film of silica will stick to the printed part. people are already doing this with salt in...

    I will either be using aluminum strips wound up, or 3d printing it out of PLA or PETG. How can I apply a coating of silica to the surface of either of these materials so that it can hold and release the moisture of the incoming air/outgoing air? This is to manage heat and humidity in my...

    Does Polyester resin + catalyst react with uncured polyurethane foam?

    I left it on for about 3 weeks, most of the time it was in below curing temperature, sometimes below freezing, but i gave it about 15 hours of 20c+ to try to cure it. It never did, and still smelt really bad. I decided to rip off the resin that had hardened. Underneath it, the polyurethane foam...
