Yizhou, might want to read up on PETG. It is not a flexible filament. It is a filament that has the toughness of Poly carbonate but prints like PLA for the most part. it is more sensitive to the first layer height and if too low or too high can cause strings. But it is not a flexible.

You are right, PETG is not flexible. I got wrong impression because when I search for flexible filament, PETG always show up with TPU, don't know why. Have not tried anything other than PLA and ABS mostly for price reason.

Yes the filament is not soft at all and will pass through Bowden setup just fine. It acts like pla only it's twice as sticky. Pay close attention to the first few layers, stringing is greater than pla but the specs say it is supposed to be stronger. It melts at a higher temp, so it won't melt in your car( hot southern places) but is stiffer. I personally don't use it but I have a friend that swears by the stuff.

I use it exclusively on my FDM printer. As long as the first layer is right and the temp is right PETG is great for nearly everything.
