um3 issues - Adhesion problems with ABS

Posted (edited) · um3 issues - Adhesion problems with ABS

For the life of me, I cannot get ABS to stick on the bed of my UM3.  I've tried blue tape, ABS juice, glue stick, cleaning all the oil off the glass, etc.  It always lifts off the glass.  Temps are Cura defaults for ABS.  Using auto bed level.

Compared to the UM2+ that I had, the UM2+ printed flawlessly and consistently.  Is anyone else having this is issue or can give some insight?

The UM2+ had an enclosure over the top and a front door.  The UM3 has a front door and a 3 sided top cover--not sure if this is whats causing it but my room isn't drafty.

    The default build plate temperature is pretty low in Cura (80c), which is probably based on Ultimaker ABS, but most likely a higher temp will help with most other ABS'es. I usually go for 95-100c. The printing temperature default can also be a bit low if you use non-ultimaker ABS.

    If you use the same adhesion material as on the UM2 that should not be the issue. The only other thing I can think of is the bed leveling. Is you first layer ok?

    I printed ABS on the UM3 with no issues, I do enclose the front and top of the machine.

    I'm using the same material as I did--in fact, it's the same roll I had pulled out of the UM2+. I agree that 80c is a bit low, but with the same abs juice, I had no problem with it sticking in the um2+.

    In terms of bed leveling, I had not even bothered with it since the 3 does auto leveling right? I hear the knocking sound (discussed in another thread--took me a while to discover what that sound was), which is the Z axis going up and down to compensate.

    The only difference in enclosing the machine is that in my um2+ I have a full plexiglass enclosure whereas in the 3, the top is partially enclosed (front and sides). I also have a door on the 3. I'm not sure if it'll affect it that much by letting some of the air vent out the top back of the printer

    My guess would be on the bed level then, did you do the bed calibration manually?

    It might be a bit off maybe and the automatic levelling is not able to compensate enough?

    I've printed a few ABS prints on my Ultimaker 3 and had no issues with that, i also used a door for UM2 and a top enclosure opened at the back for the bowden tubes and i had no issues (using 3dlac for adhesion and a brim also).

    BTW i changed the title of the topic to be more relevant to others (UM3 issues is not really relevant ;) )

    Thanks for fixing my vague title--I realized it was super vague after posting it and never got around to fix it.

    Did you do any large prints on your 3? My z axis hardly moves while printing, so I don't think the bed is that off--besides it prints PLA perfectly. I suppose my next step would be to try some Ultimaker NFC ABS.

      • 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.
