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.

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
         
         
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
         
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
         
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
         

         
        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura 5.3.0-Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
         
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
