3d pen for TPU95?


Recommended Posts

Posted · 3d pen for TPU95?

I've read some of the threads here on 3D pens.  In my region, it seems everything offered is more toy than tool, so my hope is that within this group someone can help get me sorted.

 

I've seen plenty of options that handle PLA, or PLA and ABS.  Most of these also have reviews that include things like 'broke on the third try'.  I don't know if any options handle semi-rigid options like TPU, perhaps that is a function of the 1.75mm filaments used (I find 2.85 plenty robust in the Cheetah line).

 

My application is a custom retaining ring for a clear acrylic face 'crystal' within a 3d printed bezel that has an undercut groove to hold the crystal and then a ring.  It would be so easy just to lay in a ring of hot filament.  Printing it in advance and trying to wedge it in there is not working too well, the gap is so small that a printed wall thickness that fits is too weak to take off the bed or push into the gap without deformation or tearing.

 

Thanks for your thoughts!

John

    I would have to dig mine out to tell you the brands I tried and liked. I wonder about some of those reviews because I feel like there is a huge user error thing going on there.

     

    The names may not be correct, but off the top of my head:

     

    3Doodler I did not care for because it uses only straight filament from them. I tried to put regular filament (coiled) and it was a mess because it would spin due to the mechanism of the pen itself.

     

    MYNT3D  I liked because it would use any generic filament, coiled or straight, and was comfortable in the hand.

     

    This is a new name, but looks like the one I got: SCRIB3D. Liked it for the same reasons I liked the Mynt3d.

     

    I never tried anything but PLA in it though so cannot advise on the flexible filaments though. Sorry.

     

    Edit: They all had a temp adjuster so that you would not be stuck with preset temps for filaments.

    It might also be a good idea to search on internet for demo-videos. Then you get an idea of how smooth the extruded sausage is, and if it fits your application. Most models that I saw gave a quite irregular extrusion, or maybe seemed irregular due to our hands moving irregularly? It would work very well for creating trees in miniature railroad landscapes, but not for smooth geometric objects.

    Absolutely. Great for rougher, organic types of things, but in no way for anything really functional. I have never seen a smooth print made from them, no matter the brand or artist.

      • 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
