Flow Rate vs Speed Calc


Recommended Posts

Posted · Flow Rate vs Speed Calc

After doing the 10mm3 flow test, I have been verifying the flow relative to speed on some of my prints. To ensure that I am not pushing the limits of my machine. This allows me to effectively print somethings quick as possible if need be.

Set the nozzle Size, then Set the limit acquired by your machine in the right corner in the max flow box. It will state the speed limits. I have set a safety factor option. A number of 1.3 works rather or just leave as 1.0. From here you can set the speeds and layer height you would like to see the total flow.

Click here for the calc sheet.


Note I made this nicer and simplified my other sheet I used. Hopefully there isn't a mistake. This is for reference only.

    I thought about it, but each printer is different and two points at least would need to be determined.

    Example: do the flow test at 185, 210, and 230. Then generate a linear equation. Then you could set the temperature which would set your max flow.

    Now each user would have to do this and input their data to generate the equation. So to avoid this I just added a SF to the equation if needed, and or they know the max value they can achieve at said temperature and simply change the value manually :)


    Nice job Cleven. I am thinking that if you could relate the flow to extruder temp. required you could display the proposed extruder temp. for the job :)

      • 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.
