We’ll that sounds cool, i’m even more interested now that i know that it could be more than just an alternative, but rather fix some issues with specific resins.
I mean, its really a nicely build machine. I am very pleased with it so far, but i don’t like consumable parts. The resin trays aren’t cheap and in 3d printing, failure is always a possibility and its really frustrating to me to keep loosing expencive resin due to failed prints in consumable resin trays. And dealing with loads of chemicals which could easily ruin the acrylic tray when your cleaning it ( happened to me last night.
So all in all i am going ahead with the aluminum tray build, should i post progress here or in another thread?
Any suggestions, or usefull requests would be more than welcome 
( like a functioning pouring lip )

Thanks for the link, but for something thats 3d printed - i think its a bit overpriced. I like customizing, so i’ll go for a milled aluminum tray simmilar to the Wanhao D7, cut a few FEP films on a laser cutter and start experimenting.
I was a bit worried when i found flaking and ragging on the side of the models that i was printing, especially the supports. I think its a bit of a stretch ( even though i am aware that is certanly does work very well, but… ) asking a laser beam to go through 4-5mm of plastic and pdms and not have any scattering along the way. I would imagine FEP film would eliminate most of the flaking issues and give better results in the long run. Just thinking out loud, every suggestion and discussion is very very welcome :))
Also, can anyone tell me if the Galvo system has the same XY resolution as the Form 2 version? And has anyone tried upgrading the laser system on the Form 1+?
