Waves and warping 3d print ABS

Posted · Waves and warping 3d print ABS

Hi All, 

 

Thanks for reading and helping, have a few nightmares with a 3D printer I bought secondhand. 

 

There's a few issues, 

There's a slight clicking noise, 

The ABS prints are warping

There's a Ghosting on the first layer

 

Any clues would be really appreciated. 

 

James

    Waves (ghosting?) on the bottom layer are mostly normal.  I wouldn't try to fix those as fixing those will cause your parts to warp even more.

     

    I strongly advise against ever using ABS.  It's an inferior material that is difficult to print.  If you need something that can handle higher temps I can recommend other materials - what is the max temp you need to go up to?  What is the part used for?

     

    Warping - yes this is common with ABS.  Are you talking mostly about the bottom layer?  Well firstly you need to add some brim.  A part that large with those square outer corners is a problem.  If you can't round the corners then add "brim" in cura settings.

     

    Much more detailed info about how to prevent warping in ABS here - by the way you really want the bed at 110C but that's hard to achieve without covering the front and top of the printer.  Your "squish" looks good though.

     

    Sorry my video is so long but it has a lot of critical information:

    Thanks ever so, will take a watch now. 

     

    The part is a case for a 5G Router for a maritime system. 

     

    The Tabs are my added "Brim" as I've got to use the whole print bed basically. 

     

    I've covered the door and sent the temp up, cheers for the tips!

    Oh.  Make those tabs rounded then.  You don't want all the lifting power to be able to be on one point (the tip of the corner).

    You lowered the fan speed as well?

     

    So even if you have zero splitting you probably still have weak layer adhesion.  A good test is to break a test part.  If it breaks along layer lines (it shouldn't) then you have weak layer adhesion.  It should break "randomly" and ignore layer lines for the most part.

     

    Most ABS prints are like this as users don't know how important layer adhesion is.  So the part looks strong.  It feels strong.  Until the moment it breaks.  Along the "grain".

    Yes got the fan lowered and it's worked a treat thank you.

      • 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 5.3.0-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.
