Re: Top-down air pocket design?

Great idea! Then you can fill the pocket with low pressure oxygen and create a dead zone, made of resin that won't harden when exposed to UV light, focus your beam right under the surface and you'll have a continuous printing machine.

Loving my top-down setup.

It seems like my top-down machine is complete and ready for printing lots of parts. It is equipped with a wiper system, but I've noticed that if you give the resin enough time to settle you'll get great results. The bracelet was printed with Makerjuice floating resin. Z resolution was setup at 30 mi...
