Tempeture Tower - Unexpected Result

Posted · Tempeture Tower - Unexpected Result

I'm running the Ender 3 S1 with std hot end and a 0.8mm nozzle.  I've printed  a number of temperature towers with PLA and PETG, different filament manufactures. 


In both cases the results point to a lower optimized print temperature than the filament minimum recommendation.  My understanding from what i read was typically with larger nozzles you usually increase temp 5-10%, not decrease. 


Anyone else experience this?

    When there is a lot of flow through the hot end then the stream of plastic is quickly removing heat and in that case most people find that higher print temperatures are necessary.  If you are printing fairly slow (which I find necessary with PETG) then a higher print temperature may not be required.

    Each printer is going to be at least slightly different.  The accuracy of the thermocouple comes into play as well.  At room temperature my build plate and hot end are always 2 to 3 degrees different.  It's quite likely that they are both wrong.


    I see a lot of project files and gcode files and people are printing PLA from 190 to 220.  That's a pretty fair spread but on an individual basis it must be working for them or they would change it.


    At higher temperatures PETG can be gooey and stringy but at lower temperatures the layer adhesion can suffer.

    I print white PLA at 200 and almost all others at 205, but I print silkies at 215 because they have really poor layer adhesion and I try to make up for it by putting them down hotter.  They require more benchwork to clean up because at the higher temp I get more stringing.


    If you are happy with the print quality you are getting from the temperatures you decide on then those are the temperature you want to print at regardless of what it says on the side of the spool.

      • 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!

      • 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.
