RESIONE Tough 3D Printer Resin, Not Brittle ABS Like Tough & Rigid 3D Resin for LCD 3D Printing UV 405nm (K 1000g)

Can this resin be machined? If so, can it also be mixed with other resins to add flexibility?

does this swell like other resin?

Why does acetone create a bubbling "skin" on this stuff? standard and abslikes are fine. cleans off with ipa with no damage, just weird. :d

Does this absorb water post print? Can I use it in parts that will be soaked in water?
