First Chain Attempt

I wanted a challenge after the printer end cap, so I designed a jewelry chain. I hoped 1 mm diameter cylinders bent into links would be strong enough, and 0.5 mm gaps large enough. I also put 1 mm supports that tapered to 0.5 mm on each link, so that the chain links didn't depend on each other for support during printing, allowing the chain to be flexible after removal from the lift. To print this small, I increased the exposure time from 13 seconds to 17 seconds. Increased exposure would cause issues for large continuous layers, but this chain had none of those.

I avoided the lift holes by turning the chain, following an "E" shape

The part of the chain near the lift supports did not print correctly. The supports for the links didn't print, but the links did, allowing each layer to float and move during dipping. The projector does not put as much light near the lift supports. I thought I had fixed this with a mask, but I apparently was not precise enough.

The chain was detailed, but I had a few issues!

The layer bottom bleed-through also fused the links together, closing the 0.5 mm gaps. The chain was stuck in the "E" shape. On a brighter note, the ultra-small supports snapped off the links cleanly.
