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 have been rather successful with Overture’s High Speed TPU. It prints really well with my Bowden tube setup and it has a semi-rigid outer shell that goes away during extrusion. It sounds like exactly what you are looking for.

    Just for a gasket you can probably turn off retraction and print most any tpu if you go slowly. Depending on the shape and thickness it might be stringy but it can probably be trimmed of burned off. Sure direct drive would be better, but for just one flat print that doesn’t need to be pretty you probably are fine.

    I have a Bowden printer (Prusa Mini) and regularly print flexible filament. The key is going very (almost painfully) slow. I’ve gotten excellent results.

    I used Fillementum Flexfill TPU in both 92A and 98A varieties.
