Review on 🌱 Revolutionizing Additive Manufacturing: ESUN Plant Based Biodegradable Photopolymer Materials by John Hall

Well first of all the resin prints well and appears to be of excellent quality. I've found that it actually smells WORSE than the others I've used (Anycubic, Elegoo) which aren't "eco-friendly". Of course it's about perception. It definitely doesn't have the "lack of smell" as some have reported. It could also be related to the color - right now I'm using grey. The real problem is the bottle design which is awful. First you need to remove the insane plastic security seal that leaves sharp points/jagged edges around the bottle perfect for ripping off protective gloves. It catches and holds any drips of resin that spill out and flow for days! The plastic/rubber gasket in the screw cap doesn't come loose properly (at least I didn't). Unlike similar seals, no hole is left when the ring is pulled in as the entire plastic and rubber seal assembly is pulled out of the bottle. The pull ring itself broke on my first attempt to pull it out, so now I have to pry it all the way out with a scraper blade to get to the resin. Be sure to put everything back when you're done, because without them the bottle won't close at all. I made the mistake of putting the cap back on and shaking the bottle and the resin spilled out everywhere. I like the aluminum bottle itself, but the whole cap really needs an overhaul. This is dangerous and wasteful. If anyone else has this problem - one thing that really helped was cutting off the bottom of the fork with a razor blade. Not perfect, of course, but at least the bottle is usable now. (My funnel barely fits in the hole.)
