    Hi, I have an A10 and I am very happy with it, and now I am planning to buy a new printer. I am trying to decide between an A2 and an A20M but while reading and looking for information I realized that I would like to buy a printer that allows me to print with flexible filament. What do you reccomend? Which is the cheaper printer you offer to use flexible filament? Is there any upgrade for the A10, A20 or A20M to make them print with flexible filament? Thanks and regards.

    • Jocelin Jia | 01/08/2020

      helo, if you want to print flexible filament like TPU, pls take our DIY models, such as PRO B printer.
