Printing on supports

Recommended Posts

Posted · Printing on supports

Hey guys,

I've been doing some printing and my model has some overhanging parts that require supports to be built first, but when its starts printing the overhanging parts on the supports, the plastic starts to sag into the support holes and the layers don't stick together well. It causes rough surfaces where you can see each individual layer and none of the layers are in a straight line. Is there any way to avoid this? Thanks

    Please post a photo. Also please specify country in your location profile setting and specify which printer(s) you have.

    I'm guessing you are talking about sagging between bridging.  If so you will get much better results with faster fan.  For example with PLA make sure fan is at 100% and if you already do that then consider lowering the temperature to 210 or 200 or even 190C (but you might have to also print slower.  With ABS you may have had the fan off to get good layer adhesion and you would want to up it to 30% fan speed (about the minimum where it will spin) for bridging layers.

    tick the white box behind the support setting and you will get the expert settings for this. There you can increase the % of support (and the angle for when support is generated..) This way the lines can be closer with smaller gaps. You can also rotate your model to change the orientation of the support (support is always generated in the same direction).

    If supports and surface quality are a major issue I tend to split model into two or more parts and assemble them with superglue. In this way I can print support-free.

      • 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.
