![]() ![]() I took the Stock Prusa 0.20 Quality profile and altered the printing speeds to all be 20mm/s. Print Speed override Max volumetric speed - 1.2.Slowdown if layer print time is below - 15.Enable fan if layer print time is below - 60.The guide is over here and it has a very scientific approach. Fan Settings Fan Speed Min - 70 Max - 90 (conflag) New Member TPU Printing with Prusa Mini - share your experiences Hello everyone, I wanted to share with everyone a cool video that helped me calibrate my Prusa Mini+ slicer settings well enough to print TPU with it.The filament settings I am using at the moment: I need to add a vent! Drying time might be longer than needed - it fits my schedule. In my Solvol Drier 50Deg for 12 hours with regular opening of the lid to exchange the wetter air inside for drier air from outside the box. Most important use dry filament - mine sits at about 25/28%rh. Dry your filament, even if freshly opened. Print cooler, slower with more retraction. I still get some stringing but the blobs seem to have been tamed. Printing with a stock MK3S+ 0.4mm nozzle - textured build plate. Thanks for the push in a really helpful direction. for the idler advice - made a good improvement and the advice about cooler temperatures and their risks. I have been experimenting with settings and the following have helped me get better results printing with eSun eTPU 95A flexible filament: Keep in mind that I’m using a Mosquito hotend and some of these settings, specially retractions, may be not optimal with a stock Prusa hotend. It helps a bit to improve the ‘cosmetics’ of the model. This article is free for you and free from outside influence. I tend to set lower values when there’re overhangs in the print. The Best Cura & PrusaSlicer Settings/Profiles All3DP. Extrusion multiplier : from 1.04 to 1.10, Hello everyone, I wanted to share with everyone a cool video that helped me calibrate my Prusa Mini+ slicer settings well enough to print TPU with it. volumetric speed : 2.4 mm3/s (for a nozzle of 0.4mm, that’s around 25mm/s of max. ( for layers taking less than 60’ to print, the fan runs at 90% ) Print fan: disabled the first 3 layers. (Use glue stick or similar if you print on a smooth PEI plate. If it serves of rough guide, those are my settings for the eSun TPU95 on a MK3S+ : You can use pliers to get a better grip in otherwise hard-to-reach places. When the print finishes, depending on the model geometry and material used, the support structure is often easily removable with bare hands. Drying the filament helps, but TPU will never be stringing-free like PLA. Supports can be turned on from the right panel or in the Print settings - Support material - Generate support material. Using supports would help but they’re very difficult to remove without damaging the surface of the model, so IMHO it’s no worth to employ supports in most TPU printing jobs. Maybe I should lower a bit the temperature and/or decrease the max. Even on angles relatively low they look rough. I’m currently using this filament on my Prusa and the results are good in general, except for overhangs. ![]()
