You could potentially design and print some quite complicated lenses. I suppose the one difficulty would be the epoxy pooling in small crevices when dipping. But then if you take that into account in the design it could be compensated for. You would need to find a way to predict the flow of the epoxy over the printed substrate.
- abdullahkhalids 5y agoThe problem is that if concave parts are dipped, the epoxy would pool and form a small flat surface at the bottom. You can't out-design that. But perhaps, there is a way of holding the concave part upside down and spraying epoxy on it that might work. No idea.
- samwillis 5y agoQuite true, alternatively you could hold the part inside a rotating drum, a bit like rotational moulding. But then it will be harder to predict the thickness. I suspect you are right about spraying, much more likely to get a uniform thickness. Maybe a combination of the two spray a constantly rotating (in 2 axis) part.
