I’ve printed probably 5 kilos worth of prints with a lot of success, but exclusively PLA. I’d like to branch out to a new material. Should I start with ABS or TPU?

    TPU really needs direct drive extruder to work well. ABS needs an enclosure, but you could just make one from an 8x4 sheet of foam insulation and tape for cheap.

      I don’t know what a direct drive extruder is but I have a Bambu A1

        A direct drive extruder is one where the motor that runs the filament sits right above the hotend. Since TPU is squishy, the long tube from a Boden setup gives it too much room to squish.

        That’s a bowden extruder, you’ll have problems with TPU.

        Try PETG, just dial up the retractions a bunch and slow it down.
