Does anyone use the 3d printer with Bowden type extruder to print TPU/Flexible filaments?
I heard that, Bowden extruder doesn't provide the enough pressure to push the filament in advance. I just wanted to know any alternative solution has come-up with anyone before purchasing new 3d printer just to print TPU/Flexible materials.
You wouldn't believe, how I print TPU with my Bowden extruder 3d printer.
I unwrap the filament from it's filament-roller manually time to time, continuously that consumed filament to feed. That way extruder doesn't need to provide force to unwrap the filament for TPU roller.
Although, you need to continuously manually unwrap and feed the filament until 3d print finish, time.

In addition to this make sure to keep your printing speed to low value & higher temperature for rated TPU. As I remember TPU need to print with much lower printing speed like 15 - 25 mm/s.
Run few test sample with different speed/stetting and there you can fine tune optimal setting for your 3D printer with requirement.
