Siraya Tech Tenacious Flex 3D Printer More Flexible 405nm UV-Curing Resin with Faster Rebound High Impact Resistance High Precision Tough Standard Resin for LCD DLP 3D Printing (500g, Flex Black)

Good resin. Easy to print with, very flexible.

It works as stated, as long as you pay attention to the print parameters specific to your printer. However, if you're aiming for a black-toned finish, I wouldn’t recommend this material—it tends to reflect a bluish tint depending on the print thickness.

Works very well

This resin isn't dark black. It is translucent, and has a purplish cast in areas thin enough to transmit light. It also sticks VERY aggressively to build plate. It was almost impossible to remove the prints without tearing and leaving some material stuck to the plate, even when using a very good, narrow and sharp tool for removal.
