The Flashforge Flex Bed made from composite fibre has really saved time, stress and hassle when removing prints from the bed of the Adventurer 3 (link here to that review: https://3dprintersuperstore.com.au/products/adventurer-3?yotpo_token=f8d02fa87999947fa4f941006c2b4591c07f718a&utm_source=yotpo&utm_medium=email&utm_campaign=map&ref=yotpo_8)
This bed heats very well, and has stood the test of time for many prints over PLA and ABS. I've loved it and the secondary bed plate that I got has come in handy for hot swap with prints.
