Anyone has some decent profile settings for TPU?


Recommended Posts

Posted · Anyone has some decent profile settings for TPU?

I currently have a couple of soft 3mm TPU filaments from Matterhackers and SainSmart.

I spent half a day trying to figure the one from Matterhackers. I was able to print some small 20mm domes that were somewhat acceptable although very fuzzy and also cloudy (it's a clear filament)

Then I tried to print a slightly larger model, and it failed spectacularly. Basically stopped extruding.

I don't know what's going on, but to save my sanity I thought I ask if any of you have been successful in printing with TPU. I'm using an UM3.



Also a side note: The default hardware profile for TPU on the printer is at 220 degrees extrusion, and the TPU I got recommends 240-260. So If I try to move some material on the printer to check the extrusion, it is not possible cause the temperature drops back to 220 degrees (from the printer profile)  when I move the menu choice from "printcore temperature" to "move material" option. I'm honestly irritated that these factory settings can't be overwritten as an option.

    I've good results using Ultimaker TPU (on an UM3, original feeders) and standard settings. Although it's a little bit stringy (especially at inner walls), the printing results are acceptable. So you could try duplicating the TPU profile and eventually change the temperature settings in that new profile.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
