I need a certain, rather complex shaped, flexible rubber gasket for a Dyson vacuum cleaner. Cutting it by hand would be a pain in the rear. My idea is to 3D-print it on my Ender. And now for my questions. a) Is it a myth, that you cannot use flexible filament I a bowden extruder? b) If no, does anyone of you guys can propose a material, that might be suitable for the above job? Thanks a lot!
I would rather convert the printer to direct drive first. There are various variations which are not expensive. I went with a cheap BMG extruder clone.
I’m going to add, that if you cannot print the gasket, maybe you can print a jig that will make the gasket cutting more accurate. I did something similar with a carpet cleaner where the waste tank gasket was leaking. I printed a jig to allow a hobby knife to trace an outline and not wander.
You can print TPU using a Bowden setup, though you will have to slow your print down speed and tweak with your retraction settings too. 95A should work, softer TPU may work though I can’t really guarantee that
It’s easier to print flexibles with a direct drive setup. There are some printable direct drive mods for the ender 3 which others have had success with, may be something to look into!
