ABS inter-layer adhesion

Hi,

 

I have previously used Stratasys ABS material with great success on there machines but have, until recently, not attempted to use ABS on Ultimakers. I now have a project where the client has request ABS as the material and have ran some samples parts in UM ABS on our S5 Pro Bundle. The parts look fantastic however, the inter-layer adhesion is terrible. Any force in the z-direction and the part will cleave quite cleanly along a layer. Parts printed so far have been with a variety of the UM recommended profiles from Cura and have also tried to increase the printing temperature. Nothing appears to make a difference.

 

Any suggestions?

 

Carl

    Hi @CarlGregg,

     

    Unfortunately your observations is also what we've seen internally. For ABS to have proper layer adhesion, it simply helps to have a heated chamber around 80-90C to relieve stresses during printing.

     

    To give you some data:

    Tensile strength in XY (ASTM D3039) = 38 MPa

    Tensile strength in Z   (ASTM D3039) = 19 MPa  


    So basically we have half of the tensile strength in the Z direction, using an AA0.4 printcore with 0.15 layer height and engineering profiles using Ultimaker ABS.

     

    Another option could be to look into the requirements from your customers and find a different material (if that's acceptable). For example, Tough PLA has exceptional Z strength of 33 MPa (if that's of importance to you). If thermal resistance of 75C is needed, PETG or CPE could be another good option.

     

    Hope this helps

    Hi,

     

    Thanks for the info. I will up the heated chamber temp as recommended. I increased the printing temp to 270 and this has massively improved adhesion. 

     

    I looked through the material TDS and was going to suggest Tough PLA to the client.

     

    Thanks,

     

    Carl

      • 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.
