      I personally have found that TPU prints best on those cheap crappy black surfaces that everyone replaces as their "first mod" to their 3d printer. I swapped to a steel/PEI plate a long time ago, but when I started with TPU i put the cheap black textured surface back on and I have never had a part curling issue.

        @whosrdaddy Yep , I think you could call it hard , when you print at 40% infill it is solid.

          @64bit I'll try one of the sheets which came with my flashforge creator pro.

            TPU likes thick layers and relatively slow print speeds (I keep it down to 50 mm/sec), retraction off. Reduce filament pinch pressure in the extruder. You can clean up the hairs after the print is finished. It sticks well to a 60-70C PEI bed surface. I don't use a cooling fan with it at all.

              O.K try again .

              First I'll try it Hot 80c , must hotter than my 50c I set it too like PLA .
              Than try tape or a covering if that doesn't work all at 50mm/s , which is 13mm/s first layer .

                @egon-net What about blue painter's tape ? , not used that for a long time on my printer

                Nope. It didn't work. It had to be polypropyplene tape, like the typical transparent packaging tape.

                    Yes, that tape! That worked for me. All the other materials I tried were like printing eggs on a teflon pan.

                      @egon-net i am using the Zimple Ziflex PEI powder coated sheet.
                      it sticks relatively good with a brim.

                        @danielkrah I already use a PEI sheet, but there's no adherence at all. I end up with the adhesive tape, and it kinda works.

                          I've only done a few bits for experimentation.

                          I just used Pritt (white glue stick for paper) and that worked fine, temperatures 70 & 240.

                            I print Ninjaflex TPU without any problems on glass and carbon.
                            Never had a problem with sticking. Mostly it sticks to much!

                              This has been my problem as well. Little bit of glue stick to act as a release agent.

                                I was originally using buildtak sheets, printing the same item repeatedly in the same location on the bed, got about 20-30 parts. Each part takes 9 hrs to print.
                                I then switched to garalite G11 3mm sheet 16months ago and still haven’t had to touch up the G11 surface. Best money spent
