High temperature needed to print with PLA


Recommended Posts

Posted · High temperature needed to print with PLA

I'm new in 3d printing tecnology. I bought an ultimaker printer a month ago and every thing was fine. But suddenly the PLA stopped comming out from nozzle.

Yesterday i was trying to figure out what was happening i found that if i get the hot end at 230 or higher temperature i can print, but with 217, which was the temperature i have been printing before , tha PLA just doesn't come out !

I need tips to resolve it !!!

Thanks every body !

    Is this change in behavior permanent? Its possible that you had something stuck in the hot end, and once you heated the head up a bit, it flushed through. You may now be able to print at lower temps again. What happens at 217, if you turn the extruder gear by hand? Does any plastic come out?

    If not you could even try heating it up even more - to 250 - and then turn the gear wheel by hand to drive more plastic through.

    Also, make sure that the extruder is properly clamped shut, with the bolt all the way to the bottom of the slot, and that the spring is about 11 or 12mm long - it should be tightly compressed, but still have some room to compress even more.

     

    One possibility is that the temperature readings are off. Did you move the head or disassemble it recently? Check that the wires on the thermocouple going into the hot end look undamaged, and make sure they are well screwed into the little circuit board on the head, as well. if you have an external thermometer, you could check the temperature with that - but bear in mind that most IR ones do a poor job of reading the temperature of the shiny aluminum block.

    Have you been in the need to re-assemble your hot end, and take the cartridge heater / thermocouple sensor out?

    Maybe the iron covering of the thermocouple has moved, and now a part of the wires are exposed.

    Is your feeder giving you enough pressure?

    When your hot end is hot, 180/200/230°C, are you able to pull your filament back out?

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!
          • Thanks

      • 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 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.
