First top layer/printing over infill

Recommended Posts

Posted · First top layer/printing over infill

Hello all,


I'm tuning a 3d printer and trying to get my print times down as I have quite a few things to print,  a problem I have run into is top/bottom print speed.

I think I have sorted out the problem as to why my top surface looks cruddy and it seems to be due to the first layer to be printed over infill.  If I print anything faster then 50mm/s the lines being laid over the infill end up broken and cause the following layers to be far from perfect.  I understand that I could probably fix this buy having more infill but at 25% it is already a big portion of the time spent printing and I do not want to add more time or more material for little gain in strength.

My thought is,  If there was a speed setting for that initial layer that is printed over the infill I could set that to 45 or 50mm/s and then bump up the speed for the rest of the tops to be 70-90mm's no problem.    If there is such a setting, or a way to effect the speed of the layers to be printed over infill separate from the printing of the other top layers please let me know.

I'm printing parts for a printer so 4-5 top layers are going to happen, and running them all at turtle speed is going to kill me on time.  The main issue is power is not totally solid where I am and I would love to be able to print more in one go, but Any print time over say 10 hours is asking for it... 

Thank you for reading ^_^

    Hey @Al_Capwn,


    Welcome to the Ultimaker Community 🎉

    There are a number of settings that you can tune to help with your situation. 

    Have you taken a look at any of the following settings?
    - Skin Edge Support Layers, are extra infill but only in the top most layers to help with a low infill percentage
    - Bridge Skin Support Threshold, will help with determining which parts of your model is printed as a bridge, improving your tuning options because than you can define Bridge Skin Speed
    - Infill Layer Thickness, really depends on your printjob, but will help you skip a number of layers where infill needs to be printed, it just prints thicker infill. 
    - Infill Travel Optimization, will help with finding the most efficient way to print infill
    - Lightning Infill Pattern, one of the fastest infill patterns around, I use it often to speed up my printjob. 
    - Shortest Zseam Alignment, This option simply minimises the length of travel moves leading towards the seam, making no effort to place it anywhere in particular. Because the travel path is shorter, you'll save a small measure of time on travel moves. 

    Is this the kind of information you are looking for?

      • 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.
